Pollution

Bears, polar bears, and coral reefs (although they aren't animals).

Nitrogen dioxide reacts with water to form nitric acid and NO:3NO2 + OH· → 2HNO3 +NO

Note: The NO can react with oxygen (2NO+O2-->NO2) to produce further nitric acid

yes yes it does

dull, boring, tedious, drab, tiresome, monotonous, humdrum, uneventful

Not a great deal because the main fuels are hydrogen and oxygen, so the exhaust is merely water-vapour. Solid propellants will produce other gases that may be polluting, but the number of launches world-wide, and the individual volumes of gas, are very small compared to anything else.

littering happens when people are careless and throw their trash anywhere

Shockwaves and thermal radiation are mainly emiited in a nuclear detonation. When the nuclear blasts hits the ground, kinetic energy from the impact will be released, similar to an earthquake, causing shockwaves. Thermal radiation, or electromagnetic radiation, a result of energy released from the nuclear reaction of two nitrogen atoms forming a carbon and an oxygen atom, causes fires, thermal burns and blindness.

fuel burning except in vehicles

Oil spills are very bad for Duckweed growth. This is because duckweed need oxygen and oil spills keep oxygen from reaching the plant.

Gun pollution is the proliferation, in the social sphere, of guns and rifles that cause and increase fear, pain, or death to humans and animals.

Definitely the burning of fossil fuels. Volcanoes emit around 100,000,000 tons of CO2 a year. Man-made emissions of CO2 comes to about 10,000,000,000 tons of CO2 per year. So volcanoes emit around 1/100th of CO2 that we do.

They didn't maintain the link well enough and also instead of getting right onto it they sat around waiting for someone else to come do it for them. They could have stopped it in just under 3 days using a method of setting concrete on top of the leak or of course the most simplest method (SWITCHING THE PUMPS OFF). But that would have cost them more money.

the results are going to come online on 22 nd January 2011

THere are places where water is abundant, and the people living there get to consume it. They don't have the money to create good enough infrastructure to pipe the water to places where it is less abundant.

Answer - Mostly humans cause pollution. Of course nature causes a certain amount of pollution naturally but not to the extent of being harmful to us at the moment.

All energy resources are pollution free. It is extracting some of the energy from those resources that causes pollution. Extracting energy, by any means, from any resource, will cause pollutions of some kind somewhere in that cycle.

There is no way to extract energy from anything without doing so in some way.

Plastics do not all behave the same as their composition and additive packages vary. Some have densities greater than water and would sink, others have densities less than water an float. many of the commonly encountered plastics (polyethylene,, polypropylene, etc.) fall into this latter classification. Higher density plastics include Silicones with densities ranging from 1.68 - 2.00 g/cm3

Because the excess steam is condensed into water and and goes back underwater where it is reheated for later use.

Improper sanitation or poor sanitation refers to the unhygienic condition that might affect the environment. The most common disease that poor sanitation may cause is diarrhea.

About 7 to 10 minutes per vehicle.

It depends on the amount driven. Every liter of gasoline burned releases about 2-3 kg of carbon dioxide and nitrogen oxides. That's 16 to 20 lb per gallon for Americans who aren't metrified.

Yes

It doesn't. Environmentalists just want us to believe it does.

Plankton are at the very very bottom of the food Chain. So, if they go extinct then whatever is the next up the food chain will become extinct and so on. If Plankton go extinct, life as we know it is over.
