I feel that whether global warming is true or not, there is still a necessity for us to change our lifestyles. Lets face it, everyone knows that coal and oil are not unlimited and when these resources do run out, we are in a lot of trouble.
It is because of this that we must see that the concept of global warming is like a signal that our current life is not practical and should be changed before its too late. Even if more coal and oil is found, we need to see the wider implications such as petrodictatorship and general public health in particulalry polluted places like beijing.
This is why we should not underestimate the power of global warming true or not.
