Leonardo DiCaprio – $1.75 Million, Belize

If you had all the money in the world, what kind of deluxe house would you buy? Many people would probably opt for their own personal island, which is exactly what Leonardo Dicaprio did. The film star, who rose to fame as the romantic lead in Titanic and Romeo & Juliet, has been very involved in raising ecological awareness. So what did he do with the island? He turned it into an environmentally friendly place with 72 residences, which he hopes to sell at the price of $5 million a property. This green paradise will feature solar energy, ecologically responsible cars and local manufacturing. Even the catering will be environmentally responsible, with bio-products from the local farmers and a ban on plastic bottles.
