That month the southern white rhino and a species of pangolin had gone extinct. Wildfires in five countries meant animals were crawling to the side of roads to beg people speeding by in cars for water. People were poisoning vultures and shooting bats out of the sky, scared of pandemics. To care more meant putting a bullet in your brain. So, like many, I had learned to care less. Silvina called it “the fatal adaptation.”
