First, Dolphin and Tuna follow the same ocean routes. When fishermen use nets to harvest tuna, dolphin can get caught in the nets and get fatally injured or drown.
Second, Dolphins are endangered due to the general demand of humans for sea food. Overfishing has contributed greatly to endangerment of dolphins. Lack of food is a major reason for many dolphins to swim into strange waters seeking new feeding grounds.

Lastly, dolphins are endangered due to water pollution. Materials are illegally dumped into rivers and washed to sea, and much is deposited straight in the seas. These materials poison the dolphins and cause health problems, which affect their reproduction, swimming speed and can even lead to death.
