Why Are Dolphins Becoming Extinct?

They are becoming extinct because they get wash on shore because of height tide and low ride and most of the time the get stuck there and they sometime get got in crab nets or in a boats propeller. People hunt for fun but it is not allowed by the law to any more for this reason but people still do it anyway for there meant and there blubber for the oil. 

The dolphins are getting extinct because there are lost of pollution in the water and sometimes korea or china as you all know go in the sea and catch-kill them for food!!!there are a lot of people who are killing these days!!!!so we need to help by not eating them any more!!!!!:)
