Oceans:
So I watched a documentary about the ocean's wildlife. Fish are animals, they're also going extinct. Cod is the biggest population that is depleting. Hi-tech fishing is the new norm which people are no able to catch a crap load of fish. In just ten years, the population of cod is going down. Jobs were going bye-bye because there was no cod left to really fish (40,000 jobs) in 1950's or so. Not just overfishing, trash is everywhere. There is so much trash in the ocean that the fish are in danger. Turtles, doliphins, every single animal is getting caught. Also when ever you buy fish, find out where it comes from. Some fish do carry toxins and diseases ( I never knew about this ). Especially if you're pregnant, some can hurt the fetus.
To know where fish come from and/or find what areas that fish were from are good, go to this site
