I am 15 doing GCSE biology. Recently we have studied global warming and the environment. Before, I did not really think about the consequences of our actions as humans on the Earth. But now i know we are facing a huge catastrophe if we don't start taking action. In the last few months I have done so much for the environment. Not just by myself, but by encouraging my school and family to take action too. I have done talks and put suggestions through to my headmaster to start a huge recycling scheme at our school. If everyone did small things and encouraged other people to we would not be facing such doom. These things don't take much thought or time and everyone can do them, so I wish they would!
