I think that the global economy should be put ahead of environment because I feel that the economy could effect more people in the now. However the environment has been tried and tested and proven to repair even when it is at its worst. I think we should change nothing and just let technology do the rest.
It takes years for fossil fuels to be created in such a large scale as oil or cole.Also, rain forests aren't going to grow back fast and easily. People who are now 2 years old are going to experience shortages in fuel and maybe even water.
Well really we need it, the world is too overpopulated. It would be better for the economy if roughly 5 billion people were killed.
