When was noise pollution first recognized as a problem?
When we first started to use artificial lighting, we didn't know how damaging it could be for astronomers are for us. Many street light in urban areas were built before we knew what the consequences of light pollution were.
How is air pollution caused by litter?
As the litter decomposes the chemicals start to vaporize into the atmosphere.
How is the Chinese government stopping pollution?
the government doesn't do anything except tell people to stop pollution. i know its stupid, though there the government so let them deal with it. BUT STOP POLLUTION NOW BEFORE IT BECOMES TO LATE!
secondary pollutant because of the it extracts a gas / smoke that contributed to global warming .
Is overpopulation a world problem Why or why not?
This is a problem for a couple of reasons. One is the prevalence of polygamy of amongst people, particularly Animists and Muslims. There was one man, if my memory serves me properly, with ten wives and over seventy children. That alone is seven children per wife. Another is the lack of birth control. The people are simply not able to prevent conception, and abortion is considered so abhorrent that it simply isn't even considered. Lastly, people have many children so that in old age, they can support them. For example, my grandparents had seven children, my mother included. Unsurprising, they own a modern house with a nice garden. All but one of my maternal aunts and uncles live in the United States, and the aunt remaining in Ethiopia owns a string of gyms and real estate in the capital.
Ideally, polygamy would be curbed, birth control's availability improved, and some kind of pension or social security introduced for seniors; in order to reduce overpopulation. Perhaps it is too high, and maybe a one-child law introduced to reduce a too-high population.
Why do pillbugs prefer moist environments over dry environments?
pillbugs respire efficiently in moist environments with their gills.
What two laws did the U.S pass in the 1970s in effort to reduce water pollutants?
One law that was passed to prevent water pollution was the Clean Water Act of 1972. This Act puts regulations on what can not be dumped in the water. There was also a pollution Prevention Act that was passed to help aid in the clean up of water.
Is the gulf oil spill still leaking?
This is a very difficult question. The answer is probably yes, because there have been so many spills. Once the oil spill is dispersed into the ocean, after a long period of time, it may be hard to distinguish from oil from a natural oil seep.
New techniques to prevent vehicular pollution?
as we know that in today's age there is much use of vehical, there is problem of fuel in developing countries like India.we should stop using vehicals. we should move by walking or by cycles.to stop this pollution we should use electric vehicals as yo bikes. ok
if any body have quotions he or she can ask
How can factories reduce thermal pollution?
Thermal means 'temperature' and 'environment' means that which surrounds you. Temperature would include the ambient heat of the air, hot/cold surfaces and sources of thermal radiation.
Thermal pollution is usually caused by Man's production and use of energy or by Man's urban conurbations. There is little that can be done to reduce this form of pollution. However, thermal energy radiates away very quickly and Man's direct contribution to the heat/cold of the environment is minimal. It is greenhouse gasses that are causing the biggest thermal pollution but this is an indirect means of thermal pollution of the planet.
Example of point source pollution?
Two examples of point source pollution would be:
Factory smoke
Waste being directly dumped into rivers and/or oceans
Overflow of raw sewage
What was the name of the oil tanker in Alaska that was one of the most harmful spills in the US?
Exxon Valdez.
A conventional bomb enclosed in a jacket of highly radioactive isotopes. However it will probably kill the builders before they can use it. This is called a "radiological weapon", a radiation dispersal device or a "dirty bomb".
Such a radiation dispersal device could be a "dirty bomb" but since the question does not include phrases like harmful, or detrimental and no limit is placed on "device" it is necessary to include alternate answers.
These would be:
- Hardware stores and similar hat sell ionizing radiation smoke detectors which contain Americium
- Jewelry shops that sell tritium powered luminescent watches
- Bone density examinations which infuse a persons body with short lived radioisotopes
- Sellers of radioactive sources to labs and inspection firms
- Antique shops with old radium dialed watches and clocks
- Earth satellite programs with nuclear power sources which burn up on reentry
- Manufacturers of granite counter tops which contain uranium
- US forces using depleted uranium shell and bullets
- Coal fired power plants which have uranium in their stack gases
- Drywall manufacturers whose products emit radon
One instance of this was in the 1950s Hanford site Green Run, where they took material direct from the reactors and processed it, allowing Iodine-131 and other radioisotopes to go out the processing plant stack and travel east over the rest of the country in the wind. Normally they allowed the material from the reactors to decay in cooling ponds for several weeks to remove these isotopes before processing. They tracked the radioactive plume from the Green Run to develop a model of dispersal, because it was believed the USSR was operating their plants this way to accelerate Plutonium production. If the USSR was doing this, it was hoped that the model developed from the Green Run data would allow accurate estimations of the size of the USSR's stockpile.
What are the environmental impacts of mining titanium?
When you are mining you could cut yourself in the process and die.
How can humans minimize ways of water pollution?
Some pollution will always result from man's and nature's activities. The secret is to get the levels down to the natural assimilative capacity of the Earth's ecosystems.
To this end people should follow all the rules from kindergarten:
- Pick up after themselves
- Don't take more than you need
- Clean-up the messes you make
- Don't wait for someone else to tell you to do the right thing
- Keep your neighbor's stuff as neatly as you want to have yours kept
- Don't make promises you can't keep
And the rule from camping:
- Leave the campground a little cleaner than you found it
Reduce, reuse, and recycle + Rethink, Revise.
Reduce: Decide what you really need, not just what you want. Think carefully before you buy, plan ahead. Does it really need to be made out of plastic, are there no other options?
Reuse: Is there another use for this when you've finished its original use; if not, perhaps you can find a choice that can be reused or at least be sure that it can be recycled.
Recycle: Use as many commodities that can be recycled in some way; either you will reuse it yourself or it is appropriate for public recycling. Don't be lazy, especially when you find plastic object (bags, bottles, etc) as litter. Pick it up and dispose of it in the most environmentally responsible way you have available. Plastics left in the environment do not decompose, they eventually find their way into the watershed, streams and rivers, then eventually into the ocean (Ref: The Great Pacific Garbage Patch, and the new one forming in the Atlantic).
Rethink and Revise: Do many aspects of your lifestyle lend themselves or create the need to use plastics unnecessarily? Do you really need to take a new bottle of water or juice to the little league game? Do you really need to buy a new bottle for window cleaner or drain cleaner? Most window cleaning products are a mixture of water, ammonia, and a non-sudsing detergent; perhaps you can make your own and reuse that spray bottle for years to come. Have you ever learned how to use a plunger or a snake; trust me, they're not that hard. If you use them regularly as needed you should never need to buy a bottle of chemicals to pour down the drain. If it needs more than these, you probably need a plumberl. There are at least a hundred different things the average family depends on plastic to do; I guarantee that if you think about it, your really don't need that or there is an alternate.
What can you do to eliminate ocean pollution?
You fight to have your voice heard. Earth and water are very closely linked and even animals such as the beaver, etc., are necessary for the good of rivers and oceans. You can form groups of people or even join groups such as "Greenpeace" to fight big corporations and our governments. The bottom line to pollution is air quality (too many cars, industrial waste and humans that cause garbage and abandon it as if the earth is a free garbage dump.)
Many species of animals are near extinct and some is caused from chemicals in the ocean, rivers, etc., and most is simply caused by humans. Trees filter our air, so it makes sense to keep as many trees up as possible (or "new growth" which means replacing the trees lumber companies take. Canada does this, but, we also have the Pine Beetle which is annihilating our forests by the hector as we speak.)
Different fuel for cars so we don't need to rely on oil companies to pollute our oceans and air quality. In fact, there have been cars around for many years (best kept secret for all those years) that are capable of running without gas. I just saw a program on TV where they are using corn (sort of like the method of an old still) and a company is actually putting this product out now. However, there needs to be more places to get the source for the car and that's coming up hot and heavy. The great thing about this product is you can use this fuel in most cars with a device added to your motor and there are people that are out there that know how to do it and are waiting to do so as soon as this product becomes more available.
There are so many ways all of us can contribute to making this a better world and we do owe it to future generations.
If you don't think you can't win against big corporations then think again. Many people have worked hard and beat corporations and Erin Brockovich was one of them (water pollution). I read all the time where someone has found loopholes in the law to nail a corporation's butt or brought corporations to their knees through the media and now people are going after the oil companies themselves.
You have the choice of joining a group to make this a better world, or, you can contribute money to help those groups out. You could write the odd article in a newspaper or magazine or form your opinion on the web or on radio talk shows. Knowledge is the key!
Let your government know you don't like it and send a message to some oil companies and other greedy corporations that you don't like it and are prepared to fight. Once you bring the reason to the front of the line it can cause a lot of media. Corporations of any sort don't like it!
With all the plastic garbage thrown in our ocean maybe cut down on your plastic consumption, recycle what you do use, and if possible maybe try volunteering for clean up. I know there are other ways just keep researching it and the more you know... WAY TO GO!
The best way to stop marine pollution is to educate the people as to the cause and effects of pollution. What ever goes down the drain will eventually go into the water. Everything that goes into the ground has to eventually make its way to the water because the earth is porous. its like a big sponge. What doesn't evaporate soaks in. What does evaporate eventually comes down with the rain. Acid rain is where chemicals and pollutants are released into the sky and when it rains, down it comes onto the mountains, into the streams, into the rivers and into the oceans. The only way to not pollute is to contain the pollutants. Since this is not totally possible we have to learn how to properly discard what we throw away. Also the oils from cars and machinery that leaks onto the roads stays on the roadway until it rains. Then it washes into the creeks, rivers and storm sewers and eventually winds up in the oceans. There are many precautions put into place to help keep this from happening and every day there are more being used, but we have to keep trying. The next time you wash your car, see where the soapy water goes. It doesn't just disappear .
Build a house that filters the ocean soaking up garbage and letting water back out
I'm not really smart but i think we should put sump pumps or somthing with the same effect that will suck up the water and run it throw a filter and then return it back to the ocean so all the little fishes can swim again and we should lock ever little dirt bag that litters i our water for life and we can come up with our own group and name it water is in us foundation were we send out mags
Ocean pollution is caused by chemicals and other debris contaminating ocean waters. Oil spills, factory run off, and litter all contribute to the issue. Although some natural events, such as volcanoes, can cause some pollution, the majority come from human activities. Fortunately, there are many things that can be done to prevent this problem.
Water is one of the most valuable natural resources on Earth, and it needs to be protected. One of the best ways to do this is to learn about proper waste removal practices. Automobile oil, paint, and leftover cleaning chemicals should all be properly disposed of, and not just dumped down the drain, thrown away, or spilled on the ground. Any of these methods can affect the local water supply, and possibly lead to more pollution in the ocean.

How is fridge harmful to environment?
To keep the food in the refrigerator cool, there is a thermally-insulated layer to keep the heat out as well as an in-built heat pump (chemical or mechanical) to transfer the heat from within the fridge to it's external environment, increasing the temperature of the surrounding air.
Which indoor air pollutant is radioactive?
Radon
Radon is a naturally occurring radioactive gas that is given off by some types of rock and soil. Radon has no color or odor. It can seep into basements and the lower floors of buildings. Radon exposure is the second leading cause of lung cancer in this country. A radon detector sounds an alarm when levels of the gas in indoor air become to high. If radon is present, increasing a building's ventilation can eliminate any damaging effects. This requires the attention of experts.
What is the effect of pollution in Antarctica?
got this from google, anyway heres your answer:This article follows on from our previous article on global warming in Antarctica. Here are some facts and figures regarding the consequences of global warming in Antarctica.
1) In the last 30 years, no less than seven gigantic ice shelves have reduced in area by 14,500 square kilometers.
2) The global warming effect on Antarctica is five times as strong as anywhere else. In the last fifty years, the continent has experienced a warming of around 4.5F, or 2.5C.
3) The Southern Ocean is warming fast. Measurements from the Southern Ocean waters around Antarctica showed an increase of 0.3F, or 0.17C in the average ocean temperature between the 50s and the 80s.
4) The global warming effect on Antarctica is rapidly decreasing its ice-thickness. For example, on one of the islands of Antarctica, called Signey, the permanent ice cover of its lakes has decreased by more than 45% in the last 60 years.
5) The famous Larsen B ice shelf has lost 3,250 square kilometers in the last 50 years. In 1995, 1995 km squared disintegrated suddenly, and in January to February 2002, the northern section of the shelf disintegrated. Nothing like this had been observed since scientists started studying Antarctica.
6) A large number of Antarctic penguins have suffered due to these changes. The population of the ubiquitous Antarctic penguin, the Adelie Penguin, has reduced by more than 33% in the last 25 years.
7) Scientists are very concerned about the fate of the massive West Antarctic ice sheet. If it collapses, it could raise sea levels by as much as an incredible 5.8 meters, which would be catastrophic for many islands and coastal areas around the world.
Antarctica remains the best guide scientists have to the impact of global warming. Many predictions that they make regarding the rest of the world comes from what they witness in Antarctica. For a variety of complex reasons, this part of the world is abnormally effected by global warming, and whilst the globe as a whole has not heated up that severly in recent decades, this region has got a lot hotter.
One of the most worrying aspects of global warming is rising sea levels, especially as most of the world's great cities are located on the coast. Antarctica is the main reason that sea levels are rising, as that is where the majority of the worlds water is locked up in ice (thousands times more than, say, the north pole). Hundreds of scientists are stationed on Antarctica as you read this article, systematically recoding the breakup of ice sheets and reduction of ice cover.
The effects of global warming in Antarctica will eventually touch all of our lives. Let's hope that society can move towards a sustainable future as quickly as possible, so that the impacts of the climate change will be kept to a minimum.
Lots of the pollution caused by plastic is from the oil and other materials that it takes to make it. Oil, which is used to make plastic, pollutes the air.
Also, this might not relate to the air in particular, but lots of plastic products are eventually thrown away after human use and put into landfills, which kills animals from choking on it, and looks terrible. Plastics take up to thousands of years to break down.
How does water pollution affect the oceans?
pollution affects the earth in many different ways. the most important way it affects the earth is that as living creatures OF THE EARTH when people inhale what is that i just call POLLUTE it can cause LUNG DECEASE. and with lung disease being a problem the government will use as much money they have on their budget to fix it and they will use anything. by those means the chances of those people living is about 40/60 and there will be no one to take care of the earth. at least until god puts something else on this earth
