Sloth Sanctuary in Costa Rica rescues and rehabilitates baby sloths. Luis Arroyo and Judy AveyArroyo saved their first sloth in 1992, and turned it into a fulltime operation within five years. Now the sanctuary protects and houses over 100 sloths. While there, researchers study the sloths so as to better understand how to help them. The sloths that can be reintroduced into the wild are released as soon as possible.
