@erblaa I hear this repeated all the time, but it's totally out of context. of course all species eventually go extinct, but each goes at various times for various reasons across tens or hundreds of thousands of years. But when one species (humans and their livestock and resources) replace and double in biomass over most others (which actually make up functioning ecosystems) in a matter of a few hundred years, this is unprecedented mass extinction, similar to a massive asteroid impact. ecosystems can persist when species extinctions happen as slow, naturally occurring processes. when most of the plants and animals that create working ecosystems go at once, the whole system breaks, down, which is what all life on Earth is currently staring down.

99.999% of every species that ever lived has gone extinct. Extinction is necessary in evolution, no exemptions.
