There has been a 44% decline over the last 20 years in the Florida Keys‚ and up to 80% in the Caribbean alone. Coral is very sensitive to changes in seawater. It requires the temperature is moderate but clean without sewage. As long as there is enough time‚ coral reefs can naturally recover a little natural damage‚ and sometimes even make the coral reef biological richer. Human activities on coral can

getting into the rivers that we get our drinking water from and it and the saltwater it is also intruding aquifers. The place where you can see the most change is in Florida because of the climate change. Because whenever it floods in Florida the seawater gets into the rivers and also seeps into the grounds. When it seeps into the ground it gets into the aquifers and that’s how Florida is losing its water. It is also pushing the freshwater more inland which is contributing to aquifer depletion. Also
