Whales

Whales face many threats to their welfare, health, and their existence. The main cause is commercial hunting and pollution. Chemicals and pesticides can poison their internal systems, while discarded rubbish like nets, plastics or fishing lines can strangle the animals to death. Whales are, just like dolphins, highly acoustic mammals. Noise caused by coastal developments and industrial activities can disrupt whales. Tourism also effects whales. They can feel very harassed, especially when they are breeding and calving.

When chemicals pollute the oceans, the food of whales also gets polluted. Female whales then pass these pollutants directly on to their young through their milk, which can result in death or disability. These pollutants also cause the lowering of the whale's resistance to disease. This means they are more likely to die from diseases.

Commercial as well as scientific whaling by countries as Japan and others remains a huge threat to the survival of certain whale species.
