Thousands of our closest living relatives have lived among us for well over a century, many in solitary confinement. We've dressed and trained them to be like humans, sent them into space and infected them with diseases.

Today, a few dedicated individuals are working hard to give these long-suffering creatures the freedom and sanctuary they so richly deserve.
