Coral Reefs
How have estuaries been effected by humans?
They have been polluted and filled in to use as building sights in the past.
Why are coral reefs so sensitive to dying?
Must have a specific temperature, water clarity and amount of nutrients for it to survive

Many fishing vessels illegally discard old fishing nets that can strangle and kill animals
