Environmental Impact of our Hobby.

Good Day:

I haven't thoroughly weighed out the evidence whether we have a negative effect of the reef environment but I believe we affect the environment.

I believe the biggest effects to the reef environment are overfishing, pollution (including agricultural runoff) and climate change.

For a look at the change of the ocean environment and tropical reefs the Netflix documentary "Mission Blue" documents the change of several reefs over 40 years.
