How can I change the world?

It is not like your trying to push a mountain but by changing your every day activities or actions, you contribute to global warming. For instances your room light, when you leave your room don’t forget to turn it off. In the UAE we don’t actually pay for electricity most of the time companies do. So we living in houses don’t realize that for every second we put the light on in our rooms we add misery to the world with pollution and the may cause and effects mentioned in posts above. So people try, it’s not too much. Myself I have changed a little on how I behave. For example, I have reduced the use of paper by using my laptop to type with instead of writing on paper. I have a program which acts like a binder where I can store all my files in, its like a note book actually, for each and every subject. I would like to conclude by saying that small changes may change the world where our future kids will live in. I hope we over come global warming and God save us all inshallah.
