Assessing The Impacts Of Anthropogenic Activities On Coral Reef Health In Ushongo, Tanzania Using Coral Diversity And Parrotfish Abundance As Indicators, Thao Mai

Independent Study Project (ISP) Collection

Coral reefs, covering two-thirds of our oceans, are vital and diverse ecosystems, earning them the nickname of “rainforests of the sea”. Despite occupying only 1% of the ocean’s floor, they support 25% of all marine species, providing shelter, nursery ground and food, all the while also protecting the coast and providing job opportunities for local communities. Considered keystone species, coral reefs are highly sensitive to disturbances caused by pollution, climate change, but also anthropogenic activities such as coastal development, destructive fishing practices and tourism, endangering their existence and the entire marine ecosystem. Parrotfish, a crucial resident of these ecosystems, often …
