A refugee is by definition a human—but should elephants and other animals qualify, too?

Imagine teams of ecologists, economists, and forensic accountants tracking subsidies and forecasting their environmental and social effects.

It might not be easy, but it’s eminently possible.

To prevent a wave of bird extinctions, nature-loving people need to protect common species, too.
