I assume you are speaking of the giant coagulation of plastic waste in the Pacific Ocean nearly twice the size of Texas. Yes. it is still there. It probably will be for some time. Cleaning it would require a cleanup effort that would make the efforts on the bp spill look small.

When the countries elected new leaders for their countries, the new leaders didn't necessarily follow the rules and other things that the previous leader believed and followed. So when new leaders came into office, they had their own thoughts and ideas about how the country should be run.

What are natural calamities?

User Avatar
Earthquakes, floods, volcanic eruptions, landslides, fires, spontaneous tree limbs falling, winds, hurricanes, tornadoes, ice storms... Natural calamities are occurences, events or phenomenon that happen in nature of their own accord.or because of man(the use of celltowers,vehicles also cause damage to air)so these may occur NEXT ANSWER A- natural- disaster- is the effect of a natural hazard- (e.g. flood, tornado, hurricane, volcanic eruption, earthquake, or landslide) that affects the environment, and leads to financial, environmental and/or human losses. The resulting loss depends on the capacity of the population to support or resist the disaster, and their resilience.This understanding is - concentrated in the formulation: "disasters occur when hazards meet vulnerability." A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement.

What do the recycling symbols on plastic bottles mean?

User Avatar
These are not 'recycling' codes. They are "Resin Identification Codes" that tell what kind of plastic it is. The number inside the triangle which is embossed on the bottom of plastic containers identifies the type of plastic from which the container is made. The purpose for this is to make it easier for folks to sort and recycle. The lower the number the easier it is to recycle as well. They do have a triangle with arrows, but that doesn't necessarily mean you can recycle them. It depends on your local area what plastics can be recycled. #1 PET(E) Polyethylene Terephthalate. This is most common of the disposable water bottles. #2 PE-HD High-Density Polyethylene (HDPE), example milk jugs #3 PVC Polyvinyl Chloride #4 LD-PE Low-Density Polyethylene #5 PP Polypropylene #6 PS Polystyrene #7 O(ther) plastic All other plastics. One popular example are the hard (usually Nalgene) coloured bottles, made with bisphenol-A (BPA). More than ever people are concerned about the products in their lives, especially when it comes to plastic. There are concerns over the safety of some of the ingredients used in plastics, particularly bisphenol A. Fortunately there are codes on the bottom of all plastics which can help the health conscientious consumer stay informed. See the link below for more information on what the codes mean and a guide to which plastics should be avoided due to potential toxicity.

Are oxo-biodegradable plastics harmful?

User Avatar
Plastics in general are harmful to the environment because they are here for 500-1000 years, and if left to be in the sun and oxygen, will fragment into smaller pieces. These smaller pieces are then mistaken by wildlife as food, and ultimately humankind eats this wildlife to complete a full, unhealthy circle. With plastic fragmentation being the enemy, OXO-degradable plastics are not eliminating the problem, but rather adding to it by accelerating this process. Also, OXO-degradable plastics add heavy metals and salts into the plastic to make it oxidize, thus leaving behind possibly toxic contaminates. In addition, there is no scientific data showing OXO-degradable plastic to be considered biodegradable (meaning that is is edible like other carbon based material) so it should not be considered biodegradable, but rather only fragmentable or degradable. Plastics are a wonderful invention that are obviously too convenient and entrenched in our human life-style to discontinue using. What we need is new plastic materials that can work in harmony with the environment rather than be a scourge to the environment. Like truly biodegradable plastics -making plastics earth friendly (like Enso Plastics) because nature, through microbial activity, can take care of the problem for us if we let it. -Del Andrus

There is NO antonym for ecology! but a synonym for it is environment Actually, "Ecology" is from two Greek words meaning "house" and "the study of." In modern usage, ecology is broadly defined as "the study of the environment and life within it (ecosystems)," and more narrowly as "the study of relationships between various forms of life (between and within species and communities)." First answerer was correct in saying there is no antonym, just as there is none for mathematics, or medicine, ...

The Antarctic environment is unique on the planet. It is not only the coldest, driest, windiest, highest and most uninhabited continent on earth, but it is also home to some of the most amazing animals. It is exactly this fascinating environment that allows these creatures to thrive. Without this fragile environment the entire food chain from plankton and krill to whales would be affected.

Asked in Environmental Issues, Botany or Plant Biology, The Difference Between

What is the difference between xylem and phloem?

User Avatar
Both xylem and phloem are vascular tissues found in a plant. Xylem is a tubular structure which is responsible for water transport from the roots towards all of the parts of the plant. Phloem is also a tubular structure but is responsible for the transportation of food and other nutrients needed by plant. Xylem imports water and minerals while Phloem transports water and food. Xylem exists as non-living tissue at maturity, but phloem is living cells. Xylem: Hard wall cells transport water and mineral nutrients Phloem: Relatively soft -walled cells transport organic nutrients "Hardness and softness" is a function of the amount of lignification and extractive content of the individual cell walls not there location in the tree. Xylem: It is a dead complex permanent tissue. Sapwood is xylem and mostly alive It is the principal water conducting tissue of vascular plants. Xylem consists of tracheids , vessels , xylem parenchyma and xylem fibres. Also ray parenchyma Also the xylem of softwoods (Gymnospermae) do NOT contain vessels. Phloem: It is a living complex permanent tissue. Inner phloem is alive. Outer phloem is dead. It is the principal food conducting tissue found in vascular plants. Actually only the first .2-.7mm of the phloem is functional in food transport. The rest is non-functioning (ref. Esau's Plant Anatomy, 3rd ed. 2006, Chap.14) also (ALFIERI, F. J., and R. F. EVERT. 1968. Seasonal development of the secondary phloem in Pinus. Am. J. Bot. 55, 518-528.) It consists of sieve cells , sieve tube elements , phloem parenchyma and phloem fibres. There are also phloem ray cells. --- Xylem consists of the inner heartwood (the dead part) and the outer portion called the sapwood (the mostly living part.) Xylem "wood" from the Greek xylon. The actual transport of the water and minerals from the roots (sap) is carried out by the outer portion of the sapwood (nearest the bark).The largest percentage of the sap is transported in the first few growth rings.

How can we slow or stop global warming?

User Avatar
The best thing that individuals can do is to get governments and big business to change. If businesses are obliged to pay the true cost of their carbon emissions, then they will adopt better practices, use renewable energy and electric vehicles powered by renewable sources and global warming will slow. Individuals can do great things in their own lives and be a great example to others, as detailed below, but we should elect and persuade and educate our governments to legislate to stop carbon emissions. That is the only way. Global warming is happening because: We are putting too much greenhouse gas (CO2 and methane) into the atmosphere. We release carbon dioxide (CO2) by burning too much fossil fuel (driving vehicles and generating electricity) We release methane by eating meat (cows and sheep belch methane) and putting organic garbage into landfills and by melting the permafrost. But there are a lot of simple things that YOU can do to stop global warming. Here are just a few. You reduce emissions of greenhouse gases through efficiency in your home, use alternative fuels and energy sources. Stop burning down forests to create farmland, Use energy sources that do not produce large amounts of greenhouse gases. ride bikes to school or walk Reduce reuse and recycle All people can slow down global warming by cutting down on their electricity use, gas, and other things that produce carbon dioxide. Buy energy efficient bulbs Trees absorb carbon dioxide, so plant trees (planting four is the equivalent of taking 100,000 cars' carbon dioxide out of the atmosphere for a year!) drive energy efficient cars such as electric, hybrid, and flex-fuel cars. Drive less per week by using public transport, carpools, bicycles or walking. Eat less meat, especially "red" meat from cows and sheep. In addition, Governments and countries have to get together and agree on a common solution. They have to legislate to put a cap on carbon emissions (to stop factories producing carbon dioxide), they have to stop deforestation and takes steps to promote new forest growth, they have to deal with waste and anaerobic decomposition that produces methane, and they have to promote recycling. They have to cut the use of chemical fertilizers whose run-off pollutes our waterways, and promote organic farming, worm farms and composting. And we can all play a part. We have to demand that our governments act now. Carbon Dioxide is produced whenever oil, gas and coal are burned (Most electricity comes from coal-fired power stations). So if we all did a little more of some of these it would help slow global warming: Stop using so much electricity. Turn off the lights when you leave a room. Turn off TVs etc at the wall instead of with the remote. Hang your clothes out to dry. Use public transport or bicycle. Recycle all those cans and plastic bottles. Buy local food and eat it all. Wear warmer clothes instead of turning up the heating. Plant more trees. and many more... Methane is produced when organic matter decomposes anaerobically (without air). This happens in the intestines of some animals (humans too), and in landfill (garbage dumps). There are millions of cattle, pigs and sheep all over the world being raised for us to eat. So every time we eat meat some farmer has to buy an extra animal just to make up for it. So, to cut down on the amount of methane being added to the atmosphere we should: Eat vegetarian meals more often Eat white meat (chicken) instead of red meat (beef, pig, sheep) Put food scraps into a worm farm or a compost bin More ways to slow down global warming: You could start by not eating as much junk food. The more you eat, the more you waste, the more you spend, and it also damages your health. Also, don't buy tons and tons of clothes. This was one of the hardest things for me to do, stating that I'm a teenager who loves to shop! Changing to incandescent light bulbs helps a ton too. It also saves you a lot of money! Another great way to help as a student is to get others involved in the Global Warming issue too. After hearing about how bad Global Warming is, they might take action too. Hey, why not get your whole school involved! You can always search the internet for ways to help if my advice wasn't good enough! Stay cool and take action! Save electricity by - turning off appliances when not used using energy-efficient light bulbs to save money and electricity hanging your clothes out during sunny days instead of using the dryer turning the hot water thermostat down wearing a jumper / jacket when it's cold instead of turning on the heater Reducing greenhouse gases Walk instead of taking the car Bike instead of taking the car Take public transport (e.g. bus) instead of the car Carpool with others going to the same location Use "Green" energy. Switch your electricity supplier to a renewable energy supplier. Renewable energy is energy that can replenish (be made again) in a short period of time. Non-renewable energy is the opposite. Non-renewable examples are coal, petrol and natural gas. To get electricity from non-renewable energy, we usually have to burn them which releases CO2 (carbon dioxide). Global Warming is the product of the industrial revolution. Goods became manufactured in energy intensive procedures that released things known as greenhouse gases into the atmosphere. They act to limit the ability of heat energy to escape the earth, causing average global temperatures to increase. The answer is simple enough, but how you can go about answering it is very complex. we close down all power plants and nuclear power plants and replace them with renewable energy sources such as wind and solar.Ban gas powered cars and replace them with electric cars,hybrid cars,h20 powered cars or a air powered cars.Close factory's and replace them with one powered by wind and solar powered ones.Recycle A lot.The answer is simple and can be done today. recycle, turn off electrical things when they're not in use, you can drive an environmentally friendly car or just drive less, these are just a few things out of many to help save earth By using your car less and maybe cycling or walking to your destination. by cycling you would cut down on petrol costs and pollution and your health would improve pleasing the NHS and you for not having to pay so much. and if people where given jobs closer to home they could walk or pedal. You can stop wasting paper to pass notes or to just draw on when you do that u are taking away a bird, squirrel, or other animals home and with all these factories up it causes the ice to melt which makes all the polar bears go instinct and we all love polar bears and penguins right. Also GREEN HOUSE GAS' is a cause of global warming and is the biggest one yet we should all protest against this its not right and need to stop it or our whole world is in even more danger and we could all die. so help save the earth and its creatures and stop global warming all you have to do is reduce, reuse, and, recycle! follow those simple steps and we will have a cleaner, brighter earth to live in thanks for all your good work! You could also do this: 1. Replace a regular incandescent light bulb with a compact fluorescent light bulb. 2. Don't let heat escape from your house over a long period 3. Cover your pots while cooking 4. Take a shower instead of a bath 5. Use less hot water 6. Insulate and weatherize your home 7. Be sure you're recycling at home 8. Recycle your organic waste 9. Choose products that come with little packaging and buy refills when you can 10. Reuse your shopping bag 11. Reduce waste 12. Plant a tree 13. Switch to green power 14. Buy fresh foods instead of frozen 15. Reduce the number of miles you drive by walking, biking, carpooling or taking mass transit wherever possible. 16. When it is time for a new car, choose a more fuel efficient vehicle 17. Fly less. 18. Protect and conserve forest worldwide By carpooling with people it saves multiple cars burning more fuel Turning off lights, tv, computer, radio etc will save electricity therefore save fossil fuels from being burnt Plant trees Recycling cans, bottles, plastic bags and newspaper Compost left over food and use on the garden Reuse house hold items that well... can be reused eg water bottles, Chinese take away containers etc By recycling you send less rubbish to landfill and you help save natural resources like trees, oil and elements such as aluminium for being lost forever. If access to urban public transit were funded by an automotive fuel tax, and bus riders didn't have to pay a fare, that would cut carbon dioxide emissions considerably. to fight climate change you can walk or ride a bike instead of using a car or bus and you can also stop cutting down trees People can slow the range of Global Warming, by simply recycling our plastic items, reduce littering, and turning off lights when we are not using them (or any electricity-based thing). Re-use, reduce, recycle. Ride a bike and/or take the bus. Walk to school or work or well, wherever possible and only drive when its a long journey! one way is to don't use your car that much A Pessimistic View: All of the above are good suggestions to reduce the emissions footprint of humankind on the planet. Unfortunately, humans have become accustomed to certain levels of civilization (and conveniences), and will not willingly significantly change their comfort level. The problem is twofold: Existing "advanced" societies consume an extremely large amount of power and require enormous amounts of raw materials and manufacturing to sustain that lifestyle. "Developing" countries look at the "advanced" countries lifestyles with envy, and feel that they should be entitled to those type of lifestyles. This is both natural and perfectly reasonable. Thus, they are rapidly ramping up their production levels, consuming ever increasing amounts of power and resources in their attempts to gain a better life. Presuming no significant change in technology, there is absolutely no way the advanced nations can cut more than 20-25% off their current emissions profiles without having a very noticeable impact on their quality of life. Likewise, it is unreasonable to ask the developing nations to significantly slow their attempts to industrialize (think about it: that's effectively asking the poorer countries to stop trying to be wealthy, and this coming from the wealthy countries?). The end result is that it is unrealistic to expect the current total emissions from the advanced countries to be reduced more than 25% per capita, and the best case scenario for the developing nations is to reduce the rate of increase of their per capita emissions by 25%. Mathematically, with a significantly growing worldwide population (the vast majority of that being in the developing world), that means that the best we can hope for is to reduce the rate of increase in our total worldwide emissions. That's right - we can't expect to stop or reduce our total emissions, the best we can do is slow down the amount we're adding more. Scientists are pretty sure we're either already at the tipping point, or will be very shortly (well within a decade). Once we hit the tipping point, that means that even if we stopped ALL emissions, there has been enough damage done that the natural feedback cycles will continue anyway for quite some time, and result in permanent Climate Change. Basically, we've missed our opportunity to avoid Climate Change - it's going to happen, and we can't stop it now. The question now boils down to: what can we do to mitigate the effects, stop it from getting much, much worse, and how do we go about planning for the long-term to slowly undo the damage that has happened. In the near term, the best solutions seem to be around stopping large-scale CO2 and methane emissions; the vast majority of the former come from power generation, and the later from agriculture. Here are some possible ideas to significantly reduce those two: Stop burning coal to generate electricity. Coal is massively polluting, and far worse than any other fossil fuel. Replace as many fossil fuel power plants with Nuclear fission as possible; nuclear fission plants have a radically smaller pollution profile. Use wind and wave power to supplement the baseline power from nuclear; to do this, most countries will have to significantly upgrade their power distribution network. Consider the use of small-scale solar by individuals (rather than set up massive solar solar fields). This can significantly reduce total power generation needs, without the massive environmental impact that large-scale solar fields can have. Develop better cooking stoves for the poorest people in the world. A very significant amount of soot and CO2 comes from wood or charcoal-burning stoves used by the poorest 2 billion people on the planet. There are several proposals to help replace them with stoves which either rely on solar heat, or are radically more efficient, yet still are both simple to use and very, very cheap. Reconsider how we do animal husbandry, both in the developing and advanced countries. Move away from sheep and cows (which are the major producer of methane) and towards goats or pigs for both meat and milk production. Redesign dairy farms to allow for the indoor housing of most milk-producing cows, so that escaped methane can be contained and captured. Look at new farming techniques, ones which significantly reduce the amount of fertilizer required (which is primarily produced via fossil fuels), and also the amount of mechanical power needed. In addition, there are several large-scale projects which we (as a global community) can undertake which will eventually lead to the ability to fix the planet's climate; these projects are extremely expensive and very long term in their effects - many of them will require decades of use before they begin to produce noticeable effects. In most cases, they're really not "fix" technologies (i.e. they can't stop Climate Change), but they can help stop it from getting worse. Nuclear Fusion as a baseline power source, to replace everything else. Fusion is completely pollution-free, but it has proven difficult to develop, and will be enormously expensive to get to a useful level (on the other of hundreds of billions of dollars). Orbital solar collectors - these are in the advanced concept stage, and could potentially be as large a breakthrough for power generation as fusion. The primary difficulty right now is not the orbital solar arrays, but developing a method to transmit the power safely back down to the surface. Large-scale carbon fixing - this involves a variety of schemes to pull CO2 out of the atmosphere, and fix it in some sort of chemical solid substance, in most cases, a form of carbonate. This can help radically reduce the CO2 concentration in the atmosphere. Currently, these methods are eminently possible, but doing them on the massive scale needed to have any impact would require a huge investment of money, and some non-trivial additional engineering work. Resalinization of the oceans - this may seem weird, but one of the major problems that Climate Change will have is a very significant drop in the salt concentration of the oceans, due to all the freshwater ice melting from the Artic/Greenland/Antarctic ice caps. Reducing the salinity levels of the oceans has a large number of very negative impacts. To re-salinate the oceans, one of two things would have to be done: massive amounts of salt would have to be mined and dumped into the oceans (on the order of millions of tons), or we would have convert a massive amount of seawater into freshwater (leaving the salt back in the oceans). There are several projects proposing to do either approach, but they're not beyond the conceptual state now. The possible benefit of the second approach is that humanity will be having a freshwater availability crisis shortly, and desalinization plants producing usable freshwater for human consumption/agriculture would be a massive boon. Of course, we can also adopt a large number of small-scale efficiency tactics to reduce our power consumption. Many scientists consider that taking individual-level basic steps (such as improving building codes to reduce the amount of power the standard house requires to light/heat/cool it) will cut emissions just as much as phasing out coal power plants - that is, the amount of reductions that an educated populace can make without noticeably changing their standard of living is very significant, but does require educating everyone about these efficiencies, and changing out laws to encourage/enforce these new ideas.

What is Global Warming?

User Avatar
Global Warming is the recent sudden (over 200 years) way the Earth is getting warmer. The word 'global' means 'worldwide' and the warming is of the atmosphere, the oceans and the surface of the earth. The earth has always warmed and cooled in the past, but this has always taken thousands of years to occur. When we talk about Global Warming now, we are referring to the unprecedented changes in temperature since the Industrial Revolution. According to the Intergovernmental Panel on Climate Change (IPCC), temperatures, averaged over all land and ocean surfaces, have warmed roughly 1.33 degrees F (0.74C) over the last century, (see page 2 of the IPCC's Climate Change 2007: Synthesis Report Summary for Policymakers Link below.). More than half of this warming, about 0.72F (0.4C), has occurred since 1979. Answer: Global Warming, Global Climate Change and other terms are used to describe the observed and scientifically verified changes in the Earth's temperature, climate and weather patterns over the past several decades. The cause of this change is attributed to the manmade increases in several heat retaining gases collectively referred to as Greenhouse gases which include carbon dioxide and methane which result from human activities and emissions which include the use of fossil fuels, agricultural practices and deforestation. Answer: Global warming: Global means all over the world. Warming means getting hotter. It is the way the earth is getting warmer, because of extra greenhouse gases that man is adding to the atmosphere. These extra gases (carbon dioxide and methane, mostly) are making the earth warmer. This warming is causing the climate to change. The early signs of climate change are showing up across vastly differing landscapes: from melting outposts near the Arctic Circle to disappearing glaciers high in the Andes; from the rising water in the deltas of Bangladesh to the "sinking" atolls of the Pacific. Reports from a Warming Planet takes you to parts of the planet where global warming is already making changes to life and landscape, and demonstrates how climate change is no longer restricted to scientific modeling about the future. It's happening now.

What are some examples of non-renewable sources of energy?

User Avatar
A non-renewable source of energy once depleted can never be renewed or replaced (or may take millions of years to be replenished). Coal Lignite Oil Natural gas Shale oil Uranium (Uranium235) They are all fossil fuels (except uranium) and non-renewable. When you use them, they're gone. Fossil fuels were formed from organic matter (plants and animals) which were buried millions of years ago. In time, the pressure of the massive weight of rock and mud which covered the organic matter created heat, which changed this matter over a period of several hundred million years to oil (remains of ancient marine organisms), coal (remains of ancient swamps and forests), and natural gas. We use these energy sources as fuel; therefore, they are called fossil fuels. A: An example of non-renewable energy is petroleum. Once it has been refined into gasoline and consumed by a vehicle it can no longer be used. Another example of non-renewable energy is coal, which, once you take out of the ground and burn, is simply gone.

How does cutting down trees affect us and our environment?

User Avatar
Trees give out oxygen. even because of them we have the rains. in short they maintain the ecological balance. If we would cut trees what is going to happen is that population won't stop growing but oxygen in the atmosphere will reduce. Another effect can be scarcity of food. and many other problems are attached to it such as less of rains will result in less water for irrigation. Less water for irrigation would result in less harvest which would again lead to less food and if this continues to happen for a long period of time then it might lead to famine type situations. Trees have to breathe to live, same as us and every living thing on the planet. They breathe in carbon dioxide and breathe out oxygen. We breathe out carbon dioxide and breathe in oxygen. We've evolved around trees; they are the main things that give off oxygen. Without trees, we're not here. Cutting down trees takes away that oxygen. If you cut down a tree but plant two new ones that is fine. Trees are living things too. The most important is, tree are necessary for rain. trees creates cold and humid atmosphere required for rain. Second, when it rains, trees hold the water and and does not allow to pass over soil which avoids floods. Third, they provide food to all of livings. If we continue to cut tree at larger extent then, it will definitely affect the rainfall and also will create a unstable atmosphere which will lend to destruction on/of earth. When we cut down trees, we are taking a home away from animals. We loosen the ground which mostly causes landslides. Trees cause shade and without that shade the ground dries up faster and there is not as much nutrients.

What are the advantages and disadvantages of natural gas for our planet?

User Avatar
Advantages: Natural gas (largely methane) burns more cleanly than the other fossil fuels (45% less carbon dioxide emitted than coal and 30% less than oil) It is easily transported via pipelines and fairly easily using tankers (land and sea) It can be piped into homes to provide heating and cooking and to run a variety of appliances. Where homes are not piped, it can be supplied in small tanks. It can be used as a fuel for vehicles (cars, trucks and jet engines) where it is cleaner than gasoline or diesel. It is used to produce ammonia for fertilizers, and hydrogen, as well as in the production of some plastics and paints. It's relatively abundant, clean burning and seems easy to distribute. It's also lighter than air, so if there is a leak it will tend to dissipate, unlike propane, which is heavier than air and pools into explosive pockets. It can be used for heating, cooking, hot water, clothes dryer, backup generator power, and so forth. Some places will supply it to your house by way of underground pipes. Natural gas is more economical than electricity, it is faster when used in cooking and water heating and most gas appliances are cheaper than electrical ones. Gas appliances also do not create unhealthy electrical fields in your house. Disadvantages: Even though it is cleaner than coal and oil, it still contributes a large amount of carbon dioxide to greenhouse gases. By itself natural gas is mostly methane, which is 21 times more dangerous for greenhouse warming than carbon dioxide so any leakage of the gas (from animals, landfills, melting tundra, etc) contributes strongly to greenhouse emissions. If your house is not properly insulated it can be very expensive. It can leak, potentially causing an explosion. A: 1. Natural gas use requires a separate and special plumbing system inside structures. 2. Natural gas is colorless, tasteless, AND IS ODORLESS IF IT IS NATURAL, requiring the addition of an odorant [one or more of several "Mercaptans"] to allow olfactory detection [smell] of leaks. 3. When gas from an underground leak travels great distances [underground], the odorant can be "scrubbed out" of the gas, thereby rendering it again ODORLESS, and therefore a severe explosion and fire hazard. 4. Being a fossil fuel, it is carbon based, and its byproducts of combustion include carbon compounds [such as carbon dioxide and/or monoxide] which contribute to the environmentally damaging "greenhouse effect." A: One disadvantage is that burning it creates CO2 emissions (although not as much as oil or coal), and CO2 is a greenhouse gas. Natural gas itself is actually a very strong greenhouse gas also (much more than CO2 in fact). Another disadvantage is that it can leak and cause fires and/or explosions. A: As noted above, Natural Gas is a fossil fuel. I am skeptical of calculations that it produces less carbon dioxide than other fossil fuels, although it does burn cleanly and efficiently. In some places, Natural Gas is considered a waste gas, and excess methane is just burnt in the atmosphere without using any of the energy it carries. For efficiency, we should be utilizing all of our fossil fuel hydrocarbons. Some communities are now investing in recovering natural gas from garbage dumps and farming for energy production. There is more of this that we could be doing. As far as fueling automobiles with either Compressed Natural Gas (CNG) or Liquid Natural Gas (LNG), the refueling process is slow (slower than using propane), and high pressures are required. And there are dangers of carrying around CNG or LNG tanks in vehicles. A: If we are to believe scientists concerning global warming, we need to look at the two products here. Natural gas is mostly methane (as previously pointed out). Natural gas also escapes into our air naturally. Methane is many times more of a forcing agent in terms of green house effect. Converting methane into Carbon dioxide (a less substantial green house gas) would reduce our overall forcing in terms of real forcing. There are several advantages to using compressed natural gas (CNG) to power vehicles. First, it is the cleanest burning fuel available. This reduces harmful emissions, which helps air quality. Secondly, there is an abundance of natural gas right below our feet. Increasing the production of natural gas would make the US less reliant on foreign sources for its energy, which would also help its national security. Third, as a result of the abundance of natural gas, it is much cheaper than diesel or gasoline. There are many areas throughout the US where natural gas is close to or less than $2 per gallon. A: The gas orduces lots of energy and is easy to transport using pipelines. D: It produces more pollution than oil and if it leaks natural gas can cause a big explosion and/or fire Answer: Advantages of natural gas: - It is a very clean burning fuel - There is an abundance of it throughout the world - the U.S. has the 6th largest reserve of natural gas in the world - It is about half the price of gasoline - It can be used in vehicles and is very efficient - It is used to heat most homes - It is easy to recover it from shale Disadvantages of natural gas: - There are only about 1,000 fueling stations across the U.S. open to the public - There aren't very many cars that use it yet One advantage of natural gas is its abundance in the U.S. Our country has the 6th largest natural gas reserve in the world. Natural gas also has the advantage of being the cleanest burning fuel available. its renewable!! it can help keep other gases from the destroying the atmosphere(good for the enviornment) and it also made vampires decay in the caves back then so there arent any more alive...(or are there?) Also natural gas is used for fuel... and other things that have to use power Natural gas is a carbon fuel so burning it generates the greenhouse gas carbon dioxide. However this produces less carbon dioxide than the same amount of energy from burning oil or coal, so natural gas is slightly cleaner than other fossil fuels.
