Common dolphins face many obstacles at the hands of human beings. They face exploitation by man, entanglements in fishing nets, hunting, as well as other human disturbances. These, however, can be avoided if the dolphin is lucky. Unfortunately, common dolphins, as well as other aquatic life, cannot avoid the pollution that is overtaking their habitats. Many laws have been enacted to protect the dolphins and other marine life.
