Question

Explain why fishing practices that affect deep sea corals are such a significant problem for deep sea ecosystems.

Answer 1

Coral can be a good food source, which it is fished for people all over. But too much of it can be bad for coral reefs. 
Using nets instead of bad fishing devices can lead to fish eating algae which is good for the ecosystem.
Traps that are too close to coral reefs can damage them, leading to death or a long time to recover.
