They support a huge amount of biodiversity and provide coastal protection from erosion. Many people mistakenly believe that the oceans may be turning to acid, and that it will no longer be safe for humans enter the water. As a result, they are particularly vulnerable to the effects of human activities, both through direct exploitation of reef resources, and through indirect impacts from adjacent human activities on land and in the coastal zone. Most coral reefs occur in shallow water near shore. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal … Tourism can also physically damage the reefs.

A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable. Coral is a miniscule animal called a polyp. Due to coral bleaching, the world has lost nearly half of its coral reefs just within the past 30 years and it’s predicted that 90% of it will be gone by 2050. T\൨e marine ecosystems most threatened by human activities are coral reefs. Coral bleaching impacts peoples’ livelihoods, food security, and safety. They also support organisms at the base of ocean food chains. Coral reefs have existed on Earth for 500 million years, providing shelter and food to many generations of ocean life.
