What we as ordinary people can do to prevent coral reefs to be extinct

Well, the most basic thing that anyone can do to save the coral reefs is to recycle. Recycle plastic bottles, drink cans, paper or anything that comes to your mind about recycling! Next thing that all of us can do is to reuse things that can be reused, such as paper or even cardboard! For paper you can actually use it to make origami instead of throwing it away! The same thing goes for the cardboard as well! Next is to reduce things, so that we will not waste anything. You can reduce the use of paper by using both sides of the paper instead of just one.
A harder thing to do is to start a recycling committee in the school. This can be done by giving a enviromentally friendly bag to each class to use it as a recycling bag. After the end of each term, weigh the bags and see which class colldected the most amount of paper which is to be recycled. The class which has the heaviest bag wins a prize(Per level, 1 champion and one overall champion)
