This is such a cruel thing to the animal especially when the animal has done no harm what so ever. Many things contribute to the killing of these innocent animals. The two main causes of these animals to die is the fisherman, and pollution. We should not let these animals become exticnt but in order to make this happen we must help the innocent creatures out. Tens of thousands die because of fishing nets.
Dolphins are very intelligent animals but are also very curious.
There are many ways that these animals can get caught up in the nets. One way is trying to get food. They see the fish in there and then eventually get caught up in them. This causes them to suffocate and can't break away from the nets. The fisherman of course have no idea that the dolphin is caught up in the net until he pulls the net out of the water.
