Do a little research before you decide that throwing our waste into the environment, in any form, isn't hurting the Earth.
It's akin to saying that because we don't acknowledge or have black and white proof that these ill-effects are happening, that they don't exist. We have a lot of information, before or after you want to call it tampered with, that suggests we are seriously damaging our environment. Visit any of the "Superfund" environmental disaster areas in the United States, or any developing country and then come back and tell me everything is fine.
Air pollution is just the same. Please do some research, and please learn to spell a few words correctly with correct grammar before replying.
