The slow shall inherit the earth

The Sloth Appreciation Society seeks to both protect the sloth and promote the truth about its lazy lifestyle. The much-maligned sloth is an energy-saving icon with much to teach us humans about sustainable living.

Slothville is the place to kick back, relax and enjoy the best sloth content on the web, get tips on slowing down and discover how we can protect sloths and their jungle home.

Founded by zoologist Lucy Cooke, who’s been documenting the strange lives of the world’s slowest mammal for the last 10 years. Lucy’s TED talk on sloths was ‘one of the most memorable’ of TED Women 2018, her sloth photos have made the cover of National Geographic,  her award-winning sloth documentaries have spread sloth love far and wide and her best-selling sloth books & calendars have helped raise money for sloth conservation.
