Since I do not know what on earth to write about I will just do a green tip.
Green tip: Turn the water of while you are brushing your teeth.
So, now you're going yeah every body says to do it and I already do. It's the truth and I'm with you on that but listen to this: All the clean water that you put down the drain could be going to people who have less water that isn't clean. In my opinion, it's easier to do something if you know why you're doing it.
