The dinosaurs lasted 200 million years on this planet and were wiped out by a fluke natural disaster. Humanity has only been around for a few hundred thousand years and we are already on the brink of destroying ourselves and every living thing on the planet. The earth is now entering its sixth mass extinction and the largest since the dinosaurs. We have effectively diminished the populations of some of our most majestic species without realizing that we could ruin our biodiversity within three lifetimes. If that were to happen it would take millions of years for life to recover and humanity would most likely be one of the first species to disappear.
