endangered animals

Why are penguins endangered?
1.Increasing in commercial fishing off the coast e.g. South Africa. Ten years ago the largest populations were on Dassen and Dyer Islands off the Cape. However, the populations on both these islands have been falling rapidly over the last few years, so much so that some fear that they may soon become unviable.
2. Penguin is extremely susceptible to the risk of oil spills. Indeed, in recent years there have been two major spills that have claimed many penguins, despite the excellent work of the volunteers at SANCCOB to rescue and rehabilitate these birds.
3. Man has introduced several animals (rats, stoats, cats, dogs, etc.) that attack penguins in their nests and take chicks and eggs. e.g. West coast of South Island and Stewart Island of New Zealand.
4. Human population grows, so people are starting to move in to the remote areas where these birds breed.
5. Global warming, all penguins live in and around the fertile cold seas. As the Earth heats up so penguins will need to move to breeding grounds further south.
