As recent research further supports the theory that a Sixth Mass Extinction of life on Earth may be underway. I've posted an excerpt from my How Do We Know? collection that I wrote a couple of years back.
Quote:
Over 98% of known species are dead – gone, kaput, vamoosed, disappeared, extinct! We will be too someday by those odds, but for now let us enjoy our time under the sun. That 98% doesn’t count the unknown species; those that we could have no idea about, like the ones just getting going when Theia struck the nascent Earth and turned it once more into a molten sea of lava. In the last half billion years there have been at least five planet-spanning extinction events in which half of all animal species on Earth have been destroyed. Could it happen again and if so is there anything we can do about it?
