The facts : The CO 2 fertilization effect is by no means going to âsaveâ us from the devastating consequences of global warming. 1  While enhanced CO 2 allows plants to maximize their water efficiency (requiring less water to achieve photosynthesis) the levels of other nutrients still limit growth.
Other island animals that are found nowhere else in the world, include the lemurs found on the island of Madagascar, the kiwi found on New Zealand, the tree kangaroo found in Papua New Guinea and the orang-utan which is found on the Indonesian islands of Borneo and Sumatra.
Some groups are represented only by species very recently introduced by humans. Missing on the island are the many species of large mammals  antelopes, elephants, zebras, camels, giraffes, hyenas, lions and cheetahs  that roam continental Africa today. The only large African mammal that made it to Madagascar prior to the arrival of humans several thousand years ago was the hippopotamus.
