Millionaire Doug Tompkins wanted to save a rainforest, so he went out and bought one in Southern Chile. Many Chileans though are not so keen on his philanthropy and regard him with suspicion.

The self-made millionaire of the Esprit clothing company, Doug Tompkins, now languishes in an Eden of lush forest, deep rivers and abundant wildlife. His massive reserve, Pumalin Park, is an oasis of biodiverstiy. Conservative politician Jaime Orpis regards the swath of land controlled by Tompkins as a threat to national security. His reserve is a strategic 100km long corridor from the Argentine border to central Chile. For a nation still on the periphery of economic success having such a staunch anti-developmentalist tying up resources is also deeply irritating. Many would prefer him to take his high ideals back home. Tompkins though, came to Chile with a dream and despite the knocks he's staying until the government agrees to protect his park themselves.
