If you want to see a coral reef, I recommend booking your tickets soon since they’re dying quickly from natural causes (made worse by people) and human causes.
Overfishing removes too many of the fish that eat seaweed, which then starts growing like crazy and poisons the corals. Since coral reefs are important nurseries for many of the fish we like to eat, overfishing creates a nasty situation: not only are stocks suffering from too much fishing, it’s even harder to replace stocks because by removing the fish, we destroy their nurseries.
Does anyone know what fish are ok to eat from a sustainability perspective? I would really rather not give up sushi.
To cheer you up, I recommend reading about how baby corals find a reef.
