Need to learn about the negative effects of recreational activities on the coral reefs ecosystems especially in resort filled areas. Activities such as snorkeling, diving, surfing, driving motoring jet skis etc. obviously coral bleaching but what else happens? please cite your information doesn\'t have to be peer reviews can be from any website

Solution

various human activities effect the recreation process of coral reefs. Like overfishing at the site of corals (especially herbivore fishes) affect the reef\'s ecological balance and biodiversity.

other than coral bleaching rise in the sea level is also a threat of coral damage. beacuse of coral damaging the sea temperature rises and increases the waterlevel of the sea. Decrease in the sea pH (acidification of sea water) have very negative impact on oceanic calcifying organisms such as coral reefs.there are some coral diseases occur and are response to the onset of bacteria, fungi, and viruses on the coral.
