Write the harmful effects of acid rain on Coral reef

OCEAN ACIDIFICATION
As more carbon dioxide (CO2) is released into the atmosphere, it also has adverse effects on the oceans. Recently, ocean acidification has emerged as another potentially serious threat to coral reefs. Seawater absorbs some of the excess CO2 from the atmosphere, causing the oceans to become more acidic. As a result, the oceans’ acidity has increased by 25 percent over the past 200 years. These acidic conditions dissolve coral skeletons, which make up the structure of the reef, and make it more difficult for corals to grow. If left unchecked, scientists estimate that the oceans could become 150 percent more acidic by the end of this century, making it very hard for corals to grow at all.
OTHER THREATS
Coral reefs are also being degraded by many other factors. The list of problems can seem endless: overfishing, fishing using cyanide and dynamite, pollution from sewage and agriculture, massive outbreaks of predatory starfish, invasive species, and sedimentation from poor land use practices. Reefs and their wildlife across the world are also affected by destructive fishing and exploitation to supply the coral reef wildlife trade. Fish, corals, and various invertebrates are all taken from reef habitats to serve as aquarium pets or decorative items. Although this trade can be conducted sustainably, wildlife populations are often overexploited to feed the demand for these animals. Sometimes poisons like cyanide are dumped into the water to stun fish and make them easier to capture. Sadly, fishing with cyanide often kills fish, corals, and other forms of wildlife, while degrading the reef habitat itself
