:Your wild guess is right on the money. About one million species of animals have been described. (86% are insects, including about 300,000 species of beetles.) Some biologists estimate that up to 50 million more remain to be discovered. Most estimates put the number of plant species at somewhere between 10 million and 30 million, with tentative consensus around 14 million. I have no idea how many more plants they think have not been found yet. So your point is very well-made -- if humanity continues its current rate of eliminating species for another million years or so, we will be as bad as whatever clobbered Earth at the end of the Permian. |

I plan on filing this away in my cranium for future (currently vague) use. Probably "Want to know how bad the Permian extinction was" not "We humans aren't so bad", though. I removed * the Dodo * the Great Auk from the list of Holocene extinction victims only because they are already included under extinct birds. |
