Step 1: Try
You definitely won’t save the world if you don’t try.
We each have to try. Each individual has to understand that if she is not part of the solution, then she is part of the problem. How can an individual fight global warming? That individual has to try. Do something. Anything. If that doesn’t work, then try something else. Even if it does work, do something in addition to the first thing. We won’t be able to stop climate change if we don’t try. This philosophy is true for all of the problems that face individuals/ society, not just climate change. So if you are trying to save the world, remember step 1: Try.
