The History of Non-Human Animals

The number of species is declining faster than it's declined for 65 million years since an asteroid wiped out the dinosaur. We actually have to care about all the other organisms we share the biosphere with partly because we're in charge. Eventually, if we mess up, we humans, we humans will really pay the price. A lot of other organisms will pay the price, but the biosphere will survive without us. Cockroaches will love it.
