Despite extinctions the number of animal types in the world is at an all-time high. This is due to a proliferation over the last 200 million years. It seems as time goes on the number of species increases. This seems to be a law on this planet and maybe the universe.
There are indications that humans could be changing this by causing extinctions. However, it will be a long time before the variation of species declines significantly. With the poles melting a tipping point could be reached where even humans are under threat of disappearing. This is just a theory at this time. Perhaps, changing the way we live will make things better for all creatures.
Human knowledge is going on a pace. There are new discoveries minute to minute. Indeed, it is difficult for specialists to keep up with all the reading that is necessary. Even general practitioners say there are not enough hours in the day to keep abreast of the latest breakthroughs.
