You can be the change you dream of.
Some hints to start with:
you buy or plant some plants in your rooftop,
you can donate useless cloths to your poor friends or someone in need.
you can volunteer to assist your neighbors children when they have homework difficulties.
you can spend some time with a sad friend who need someone to listen to her and
advice her.
you can inspire your friends to do likewise.
the world won't get happier after that, but at least your surrounding will get better.
I am assuming what you wrote is not just an essay
