“What is your personal carrying capacity for grief, rage, despair? We are living in a period of mass extinction. The numbers stand at 200 species a day. That’s 73,000 a year. This culture is oblivious to their passing, feels entitled to their every last niche, and there is no roll call on the nightly news.” — Lierre Keith, Deep Green Resistance: Strategy to Save the Planet.

Sad news swept across our global community recently in light of the official extinction of the West African black rhino, which up until now had spent a long, shaky time on the critically endangered list.

According to the WWF, the rapid loss of species we are seeing today is estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate. These experts calculate that between 0.01 and 0.1% of all species will become extinct each year (between 200 and 2,000 species per annum).
