How are coral reef dying.
Most of coral reef all close to city and town so lot of wastes from city. In waste bin their lot of things like bottles, food waste, liquid waste and more. So they put the wasted in the water that goes to coral reef faster then it damage the coral reef. Also they is another way coral reef can be damage by fishing. People like money fishing around coral reef they caught over 1000 fishes in one day it is called over fishing. Also !!!!!!! people crossing over the reefs with boats so that damage the reef.
