The commitment must be much deeper - to let no species knowingly die; to take all reasonable action to protect every species and race in perpetuity.
E. O. WilsonThe vast majority of species that are vanishing, we haven't even discovered yet. How can you possibly put them back in nature if the ecosystem is gone?
E. O. WilsonWhile ants exist in just the right numbers for the rest of the living world, humans have become too numerous. If we were to vanish today, the land environment would return to the fertile balance that existed before the human population explosion. Only a dozen or so species, among which are the crab louse and a mite that lives in the oil glands of our foreheads, depend on us entirely. But if ants were to disappear, tens of thousands of other plants and animal species would perish also, simplifying and weakening land ecosystems almost everywhere.
