Hello there
As u surely know, Our planet is in danger and WE are the problem! 
...but it is still time to fix this and u can do something!
GREENPEACE.org...they need your help!
We are the problem.. As long we're alive we'll end up destroying our closeby enviroment. The choice is to suicide.. lesser people results into lesser polution.
Sounds extreme, but amazingly enough the only solution.
Becoming a vega wouldn't do the trick either.
In comparison to killing animals, you either eat or cook plants alive. Sooooo.. If a plant would have a mouth, it would scream into agony, pretty much with animals.
So stop eating? A perfect solution, but we all need food, and somehow we end up gnawling if we get not much. So we end up eating everything.. unless someone becomes a fruitarian.
Last but not least: greenpeace might step up for the enviroment, but theres no real working solution that is both peaceful and effective to save the world.
