I don't think a lot of people read this. It is interesting information. I had to take a tree hugger science last year and one of the things the professor admitted to is that another one of the destructive gases to the ozone that they beleive is causing the global warming is ethanol, and uria, which are both caused by natural body occurances, the ethonal comes from Pooh, while the uria comes from Urine. Not just human but animal as well. I personally don't know, but am refreshed to see another prospective on the whole thing. Now they can prove all of it, inclucding the CFC part Maybe we can all use Aqua Net again.

Why the reversal of roles to begin with?\n\nAir would naturally be cleaner in a country setting with less industry and traffic... if out of the path of smog coming from any nearby city.\n\nNot a lot worthy of debate here.

It is important because of the enviroment. The animals, the air quality all need to be very clean. If an area doesnt stay clean, the enviroment will become nasty

The Water Pollutance is when the water is dirty for non naturals causes.\n\nFor example, in a stream, the water pollution could be affect this place and the people maybe can't note that ... Why? because, some pollution agents are unseen to the human eye ... for example ... NO2, NO3, S, P, etc, etc ... all this elements in excess in a stream, river, creek, lagoon,  wherever place whit ater ... could be contaminated ...\n\nBut, you could get more information in this link:\n\nhttp://www.dbmain.biz/4/water-pollution/epa%20water%20pollution\n\nIs a link from EPA .... Enviromental Protection Agency...\n\ngood luck !!!!\n\nPD: Please, excuse my english .. I'm learning to write in this Idiom.

Yees everyone should practice Ahimsa. Do no harm to anything. If more people did then the world would be a much better place. \n\nIf every person not only picked up their own trash but picked up a few extra pieces left by someone else each time it would do wonders.\n\nPeople are not taught to do these things. Integrity is a rare commodity these days. \n\nParents need to teach their children.\n\nAnd to the previous poster YES we can make a difference. We are after all the ones who created the mess so it only stands to reason that we can fix it as well. It is attitudes like that that perpetuate the problem. "Oh forget it we can't do anything so why try?" Thats crazy. You don't have to be a tree hugger to care. Just have some respect. Its not about the earth being able to eradicate the human race and take care of itself it is about quality of life and respect. If people cared more for others and the earth there would be more peace and a much better quality of life for everyone while we are here. Perhaps the earth wouldnt feel the need to eradicate us if we take better care of it and were not a negative influence.

For most muslim countries, only cleaning with water is sacred.  They must present themselves at least 5 times a day for worship and any form of uncleanliness is taboo.  Wiping clean with toilet paper is not clean enough.\n\nUnless the nation is very into the environmental friendliness policy.  Imagine how many trees they save!

I don't know about the other mammals, but in humans it has been suggested that the drive in human infants to eat dirt is an adaptation to train the undeveloped immune system. This may or may not be related to putting other things in the mouth.

It is a cause of soil erosion but not soil pollution. Soil pollution happens due to untreated water

Dirt is what gets tracked into the house on your shoes.  Soil is the provider of life on much of the Earth.  Soil is formed from weathered rock- I suppose humans could artificially do this, but not on a cost effective scale to, let's say, have a hundred thousand acre corn field.

if all the rivers and streams become polluted,certainly the balance of ecosystem will get disturbed.The only result will  be the perish of life from earth.

Equipment you use, materials you throw out.  Think of a bulldozer (equipment) pushing dirt (material).  You keep the bulldozer and get rid of the dirt.\n\nGood luck.
