The 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?

Biophilia: the innate pleasure from living abundance and diversity as manifested by the human impulse to imitate Nature with gardens.

Science and technology are what we can do; morality is what we agree we should or should not do.

Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level.

Destroying a tropical rainforest for profit is like burning all the paintings of the Louvre to cook dinner.
