Because fisher hunt tuna but also hunt the dolphin and kill them.
Not all types of dolphins are becoming extinct. Most dolphins that die of an unnatural cause, die in tuna fishing nets.
they get endangered by people trying to catch them
When Japan killed like 20,000 dolphins ever year. Then then get caught in tuna nets and tuna is mostly dolphins meat.
some are being caught unintentionally and they die before somebody realizes about them, and some are caught in the intention of getting their blubber or skin.
Things like pollution, oil spills, fish dying out, Tuna fishing (the dolphins eat tuna, and sometimes the dolphin gets caught in the net) things like that.
If we keep on hunting on dolphins! And that's a bad idea!
because people are throwing things in the waters and fishing and swimming where they live
Human activity and pollution will probably be the greatest cause of elephant extinction.
