Would burning used plactic bags be better for the environment then dumping them in landfill?
Plastic bags are generally polypropylene or polyethylene. Use as a fuel would present no problems if they could be gathered for combustion. Alternately the bags could be recycled as plastic feed stock for low end uses.
It all depends on what happens to them. Say for instance someone is bothering them and they want them to know but with out words they'd groan loud enough so they can hear it. A groan is made low in the throat to show pain, sorrow, anger, or grief. When someone is in trouble or if they got grounded they'd groan or moan since they probably didn't do anything but got blammed anyway. Or if someone's in pain and it hurts so they won't cry they'd groan and say something like "Ow that hurts!". or just a simply OW would do it. Hoped I Helped Ya.
Why don't they use natural gas in cars?
They do, but the fuel is more dangerous to handle and the infrastructure is more expensive than with regular gasoline cars.
Do all atmospheric gases contribute to the greenhouse effect?
Not all atmospheric gases contribute to the greenhouse effect; only certain gases, known as greenhouse gases, have the ability to trap heat in the atmosphere. Key greenhouse gases include carbon dioxide, methane, nitrous oxide, and water vapor. While gases like oxygen and nitrogen make up a large portion of the atmosphere, they do not significantly contribute to the greenhouse effect because they do not absorb infrared radiation. Thus, only a subset of atmospheric gases plays a critical role in regulating Earth's temperature.
What are the causes of air pollution?
The combustion of fuels in automobiles, jet planes etc all cause the release of several primary pollutants into the air. The burning of fossil fuels in big cities which is seen at most factories, offices and even a large number of homes.
Furthermore is the release of other harmful gases all adds to the state that we see today. Although carbon dioxide plays an important role in various other processes like photosynthesis, breathing an excess of the same also causes harmful effects towards one's health.
A:The various causes of air pollution that releases harmful gases into the atmosphere are caused due to the increasing number of power plants and manufacturing units or industries that mostly have activities related to the burning of fuels. Besides, as mentioned earlier, most automobiles, marine vessels, activities that involve the burning of wood, fumes that are released from aerosol sprays, military activities that involve the use of nuclear weapons, all are the numerous causes of air pollution. A:Air pollution takes many different forms and arises from a variety of sources. In terms of overall range and extents of impacts, however, it is my opinion that burning of fossil fuels (coal, gasoline, etc..) is the single largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions, and dispersal of some heavy metal contaminants. Fossil fuels are widely used for heating, transportation, electricity generation, manufacturing and other industries. Thus, they are used pervasively in our society and their use is difficult (but not impossible) to curtail. Also, various measures can be taken to help make fossil fuel burning both cleaner and more efficiently but this comes at some monetary cost. Until we find cleaner alternatives to the present fossil fuels burning methods, most air pollutants plaguing the world today will continue to be a problem in the future. A:Stationary Sources include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices.Mobile Sources include motor vehicles, marine vessels, aircraft and the effect of sound etc. Chemicals, dust and controlled burn practices in agriculture and forestry management. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest. Fumes from paint, hair spray, varnish, aerosol sprays and other solvents Waste deposition in landfills, which generate methane. Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is reduced to below 19.5% by displacement. Military, such as nuclear weapons, toxic gases, germ warfare and rocketry.
Natural sources Dust from natural sources, usually large areas of land with little or no vegetation. Methane, emitted by the digestion of food by animals, for example cattle. Radon gas from radioactive decay within the Earth's crust. Radon is a colorless, odorless, naturally occurring, radioactive noble gas that is formed from the decay of radium. It is considered to be a health hazard. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as the basement and it is the second most frequent cause of lung cancer, after cigarette smoking. Smoke and carbon monoxide from wildfires. Volcanic activity, which produce sulfur, chlorine, and ash particulates.
A:Many things can cause pollution. Smokestacks from factories, trucks and cars (vehicles), and even smokers pollute the air. Some have a larger impact on the air than others, but CO2 and smoke, etc. are what most people are talking about when they refer to "pollutants."And, not only that, it can be caused also by cars, rubbish, factories, smoke, power stations are also some of the things.
Special note: We should stop air pollution by stop to do the things above. It is our responsibility to stop air pollution and our rights to breathe in clean air.
What questions should you ask about climate change?
- What is causing climate change? (Global Warming)
- What is causing global warming? (Burning fossil fuels, deforestation)
- How can we stop climate change? (Change to renewable energy instead of fossil fuels)
- What can we do at home? (Don't waste any electricity. Reduce private transport use)
- How can we change governments minds? (Vote for Carbon pricing and Green energy)
What type of mixtures are in polluted water?
A polluted water may be a homogeneous or a heterogeneous mixture.
What are the positive human impacts on the ocean?
nothing
people cant do anything right because we are very selfish =P
actually, humans can right their wrongs by setting up marsh clean ups for the dirty oceans, save the aquatic animals build in relief wells that could suck in the oil from the water. humans also have a positive impact on the oceans because it is beneficial to our health and resources :)
All landfills leak a certain amount over time and it is impossible to completely prevent all contaminates from doing so. There are government regulations on the allowable amount of leaked material and the proper location of a landfill in relation to water ways and residential areas such that the the risks associated with the leaks are minimal or negligable and site is monitored year round. All landfills incorporate geotextiles and other liquid tight fabrics to retain most of the material that could possibly leak from the landfill and technology is still developing to further reduce the amount of leakage.
What causes plastic particles in the toilet tank and faucet aerators?
actually these are oxidized minerals found in hard water you either need a water softener or a salting system
Why is it called global warming?
It is called global warming because of greenhouse effect.and greenhouse effect happens when there is too much greenhouse gas in the atmosphere. Greenhouse gas is used for trapping some of the sun's heat for the earth's warmth.And when there are too much Greenhouse gas, all of the sun's heat gets trapped inside the earth, causing the earth's temperature to rise. Greenhouse effect is normally caused by human activities such as burning fossil fuels.
It depends on the location. During the times that Azerbaijan was part of the Soviet Union (USSR) there were many chemical factories in Azerbaijan. The areas around some of these factories are polluted. but these days the government is cleaning up pretty fast.
However, overall Azerbaijan has very clean air, and the outdoors is very beautiful. Particularly since the country is very mountainous, many of the mountains are clean and great for hiking and visit.
Hiking along the Russian border is very nice.
because of the people who dump rubbish everywhere. also rivers are polluted because of waste, pesticides etc.
How you just spelled it.
You spell it like this: P-O-L-L-U-T-I-O-NHow do you protest against deforestation and harm on the environment?
There is no way to completely stop it but I urge you to try because we could not live without trees and plants. Making signs and tyingyourself to a tree are good examples if you don't die. You could also make a paper or document and send it to an important person so that you have a chance to get it to a council.
How much aluminum is put into landfills from gum wrappers each year?
850 metric tons. That is equal to 60 million soda cans.
the mixyute of smoke,fog and sullphure dioxide form the sulphurous smog.
How many liters are in the air?
The Wikipedia uses the value of 5.14×1018 kg (5 140 gigatonnes) for the mass of the Earth's atmosphere. Every 22. 4 liters will weigh about 30g (1 g-mol air = about 30 g = 22.4 liters)
There would be 22.4 x (5.14 ×1021/ 30) liters of air (about 4 x 1021 liters) at STP (Standard Temperature and Pressure).
However, the Earth's atmosphere varies in temperature and pressure as you travel from 0 miles to 60 miles above sea level. Pressure is noticeably different in the mountains (a few miles above sea level) so that cooking instructions must be changed. This is even more pronounced by the time one reaches the stratosphere at 5-10 miles altitude.
Moreover, the air we breathe does not circulate much above the tropopause. So a closer, though still incorrect, approximation to your question (using the same Wikipedia numbers) would be to assume the air we breathe goes up 11 km in altitude (tropopause varies from 7-17 km above sea level; using a lower than middle number to account for some of the drop in pressure and for mountains) over 197 million square miles of Earth's surface area. This makes a total of
1.3x10^9 mi^3 (cubic miles) [WolframAlpha.com]
of space, or
5.6 × 1021 litersup to the tropopause. Air has stopped acting as we understand air near the ground to act by this height; but let's compute the height at the exobase (the height at which air ceases to act like a fluid because the particles are so far apart). At 60 miles times 197 million square miles that would total4.9x10^22 liters.
Why is the effects on littering so bad at public places?
Littering is a nice word for throwing garbage in a public arena. It lowers the standard for civilized living, it is inconsiderate, it is unhealthy, it is aesthetically unpleasing. Littering stems from a sense of entitlement from being over-valued, or from a sense of hostility thinking that one needs to make one's presence known - kind of like a dog peeing to establish territory. Both ends of the spectrum are suggestive of narcissistic personalities, and imply a lack of willingness to get along with humans, as a human.
