Zoos today play a huge role in the survival of wild animals. The extinction of wildlife is taking on more and more dramatic proportions, and it seems very difficult to stop these processes, but zoos can also play a key role in this fight. In the old days of course, everything was better, the animals could live freely in untouched natural conditions. Compared to Earth’s state many thousands years ago (but even a hundred years ago), the change caused by humanity is dramatic. We have to re-learn our the role on Earth because the ancient state of paradise can no longer be restored.
