All around the world, there are many endangered animals, largely because of human progress. As the world’s population grows, humans move into new areas, create more pollution, and use more natural resources. This all puts pressure on animals, which cannot really compete with humans. An excellent example of this would be the case of the leatherback sea turtle.At 6.5 meters long, and up to 600 kilograms, the leatherback is the largest turtle on earth. It is also one of the most endangered. Scientists do not know the exact number of leatherback because they spend their entire lives at sea. This makes them very difficult to cont. but female leatherback come on land to lay their eggs. From the number of nests that scientists find, they can estimate the number of turtle. The number do not show a good future for the leatherback. At one beach, scientists counted over 1,000 egg nests in 1954. in 1933, there were on only 50 nests at the same beach. Scientists think that the leatherback population is perhaps only 1 % of what it was just 50 year ago. Human development over the last 50 years is undoubtedly the reason for this.
