Millionaires are buying large tracts of land to protect the environment as oppose to destroying it.

Parque Tantauco, which Piñera created in 2005, is on one of South America’s largest islands, Chiloé, off the coast of Patagonia.

Piñera bought the land and immediately set about protecting the offshore habitat of blue whales and the inland virgin forests.

Pulling out a map of the park, Piñera explains his plan, tracing his finger over a trekking route that will be connected by rustic cabins.

‘We have been buying all the land around us. We started with 110,000 acres and now we have 150,000,’ he says. ‘I want my children and grandchildren to remember me for making one more million? No! So I now have many projects like this.’
