Imagine a planet without Elephants? They are the gardeners of the ecosystem. Tsavo, Kenya is an ecosystem in itself, the park covers 22,000 square kilometers. and if the mega herbivore was not there, then there it would get covered in wooded vegetation very quickly. This allows other animal species to thrive as a direct result of their natural work. Poachers however have killed many of these wonderful and one very famous Elephant.
