Pollution can come in the form of oil and chemical spills, from human waste and from increasing noise levels in the water, all of which can have a terrible effect on whales and dolphins
A whale or dolphin hit by a vessel (boat or ship) is likely to die or be severely injured and these collisions now threaten the very survival of some endangered species
Climate change is a major threat to whales, dolphins and porpoises. The climate is changing fast: so fast that some whale and dolphin populations may be unable to adapt.
