There's less than 10 years remaining to save Sumatran elephants, says guest Leif Cocks, founder of the International Elephant Project, so we followed up with him to learn what is being done to save the critically endangered species' shrinking habitats, and to discuss the growing movement to recognize their 'personhood' and thereby ensure their interests are considered in development decisions.

Leif also shares his thoughts on a planned hydropower dam in North Sumatra, sited in the only habitat where the last, critically endangered Tapanuli orangutans live. This project has also, tragically, claimed the lives of 16 workers in less than 2 years.
