Re: 99% of species are extinct

We might want to look at how our actions can alter ecosystems in a positive manner, but it can be fearfully complicated stuff to figure out - plenty of mistakes have been made in that regard (both on what is a positive manner and on how to do it).

Ya, very complicated. Knowing what satisfies me though, and what things I consider desirable and undesirable, is pretty simple. And since we are a natural result of our eco system, would you agree that the things that tend to be desirable to us will tend to be best for the "system" as a whole?

Perhaps that was the type of thought that has me wondering if there is such a thing as 'normal for the system'. Two years ( 2,000 years?) after the dinosaur wipeout, the planet likely had a comparatively low number of species on it. There were previous mega wipeouts also.
Niches seem to create species, specialists really. As long as the planet remains a environmentally diverse place, any non-total wipeouts will be temporary? Will they be as diverse over time?
Does the 99% extinct figure contribute anything in such discussions?
