Tonight on 60 Minutes here in the United States, there was a special about Gorongosa National Park in Mozambique. An American entrepreneur, Greg Carr, cashed in with a partner as the co-inventors of voicemail. Greg walked away with $200 Million and decided to put his entrepreneur skills to work to make the world a better place.

Gorongosa National Park is a 1,500 square mile park in the middle of Mozambique which was an extremely popular tourist destination around 50 years ago. Wildlife was plentiful. Multiple wars sent the country into poverty, and the wars combined with poaching decimated the animal population - especially the big game.

Greg is working on helping the people of Mozambique and actually has an agreement with the government of Mozambique to develop the park over the next 20 years. The key is to bring in more wildlife which will in turn bring in more tourists which will help to prop up the local economy. Greg is doing this responsibly and has a team of scientists to ensure that he reintroduces the right species into the park in the right manner.
