Oysters used to be so abundant they were a poor people's food. It's hard to understand how overfishing, overhunting, and habitat destruction have destroyed ecosystems.
Some people think we can just pretend we're not part of an ecosystem if we pour enough concrete. It doesn't work, it just makes everything worse. A damaged ecosystem is not just unpleasant but physically dangerous to us. A flooded coastal base will soon be the least of our concerns. We need to fix damaged ecosystems and replace destroyed ones
