I've learned about the coral reefs that they are stone like substance , their are one of the most beautiful attractions near sea side , but unfortunately , water pollution is a big risk for these natural creatures , they've been formed millions of years and it would be a waste losing them , as there are a thousand of species that were undiscovered . Helping cleaning the water can solve this problems that form due time and volunteering can really help a lot .
