During our planet's history, there have been 5 events that wiped out the majority of the life on Earth. The last one was the extinction of Dinosaurs about 60 million years ago. I want to answer to following questions. First of all, when will the next one be? I also want to know what the cause of it will be. In addition, I want to know if humans are helping to speed up the process. The most important question however, is whether or not we will be included in this extinction.
