I have a new article up at Mental Floss called 9 Controversial Experiments In Rewilding. Excerpt:

Strange as it is to imagine, at one point lions roamed Europe, horses galloped over Spain, and jaguars prowled parts of the United States. The reason these animals died out wasn’t climate change, but humans hunting or destroying their territory.

Rewilding is an effort to bring species back to their native habitats, even if they haven’t lived there for thousands of years. The idea isn’t just to preserve an ecosystem, but to go back in time.

Read about wolves in Yellowstone National Park, wild Mongolian horses, and Jaguars in Mexico HERE.
