About 600 aquatic species are raised in captivity in about 190 countries (there are currently 197 countries).

Pollution of the marine realm
- 5 times more garbage is dumped into the ocean than all the fish caught on a commercial basis
- 60 to 80% of marine litter: plastic
- 1975: World fishing fleet dumped approx. 135,000 tons of plastic fishing gear and 23,600 tons of synthetic packaging material (Cawthorn, 1989)
- Study in North Pacific: 8 out of 11 birds examined had plastic particles in them
- Plastic found in 86% of all sea turtles, 44% of all seabird species, and 43% of all marine mammals (Laist, 1997)
- Extinction rate increased between 1,000 and 10,000 times of the natural rate (Lovejoy, 1997)
