And I hope Jill Tarter's wish to engage Earthlings includes dolphins and whales and other sea creatures in this quest to find intelligent life elsewh… - Sylvia A. Earle

The next time you dine on sushi -- or sashimi, or swordfish steak, or shrimp cocktail, whatever wildlife you happen to enjoy from the ocean -- think of the real cost. For every pound that goes to market, more than 10 pounds, even 100 pounds, may be thrown away as bycatch. This is the consequence of not knowing that there are limits to what we can take out of the sea.

(What is the biggest threat to the ocean right now?) Deep-sea mining. Some are buying into the lie that we should be taking minerals that are necessary for today’s generation of [EV] batteries, like lithium, cobalt and nickel, from the deep sea, because who cares what happens in the deep sea? These deep-sea systems are full of life and are part of the biogeochemical cycling systems that hold Earth steady. If Earth functions like a big computer system with all these little wires and lights that we don’t understand but we know it keeps us alive, would we want to get in there and take those little lights out because we don’t understand how they work?

Knowledge is the superpower of the 21st century. Even the smartest people alive when I was born did not know what 10-year-olds today have available to them. That’s truly cause for hope.
