Since dinosaurs extinct, mammals are the most species in the world. However, the extinction is happening again, called the 6th extinction. Each extinction would wiped out almost species, include human being. Species are varnishing quickly and faster than our estimate. The research show that larger animal even vanish faster than smaller animal, such as whales or sharks. Furthermore, we all live in this planet, Earth.
Our mother nature is dying now, but we don't seem to care about it. That's why I need to talk about this serious question. We should follow this important issue and next post will tell you more about the 6th extinction
