Global Warming ...who is responsible for this situations?

i think that the countries that didn't sign or respect the Kyoto document are the responsible of part of the global warming.

We are responsible. We always thing and say that government must do something to take care of this. We ever think even what we can do. Do we move out a day with out our vehicle. No. do we live a day without electricity No do we ever oppose to someone who is cutting any tree.No think if all these things can be done some time by all the population what we can do in a long run what government cant do ever. What about our part of doing..
