"Dead zones" off western US coast ...

[highdesert]

Greetings -

As I'm not a regular in this area of Scubaboard, I suspect this issue is already posted ... just a link here to a follow-up report trying to determine the impact of increasing areas of hypoxic ocean. As more people require more and more food, where is it going to come from? Will it cause total ecosystem collapse? No answers from me, just concern ...

Here's a short video, then scroll down for the article ...

Interesting.

We get these dead zone here in the Chesapeake Bay, but we can usually link them to algae blooms that get a boost from agricultural runoff.

I don't know if it was mentioned, but right now these appear to not have had human contribution. Did I understand that right?
