"We’ve been hearing it for years: The world is in the midst of a biodiversity crisis, with species going extinct at a rate 1,000 times faster because of human impact on the environment.

Most recently a report from the United Nations’ Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services estimated that as many as a million species risk extinction in the coming decades due to human-related activities.

All of which raises the question: If so many species are going extinct, why don’t we hear about new extinctions every day?

The answer to that question is more complex than you might think."
