Species on Earth are disappearing at an alarming rate. The Earth has already experienced five major mass-extinctions caused by such things like climate change, volcanic eruptions, and an asteroid crashing onto Earth. Signs show that the sixth extinction has already begun and it’s predicted to be the most devastating since the asteroid eradicated the dinosaurs. The Sixth Extinction opens our eyes to how human behaviour has altered (and continues to alter) life on the planet and how it is causing (or may have already caused) the next mass-extinction.
