I'm not going to go into great detail about who Douglas Tompkins is. Suffice to say he's a filthy rich US businessman who bought a massive chunk of Chilean Patagonia a few years back and then turned it into a private eco-reserve. The Chilean government then realised he'd bought pretty much from the coast to the Andean border, thereby cutting off overland access to further south. This caused quite some uproar amongst Chileans, who thought the filthy gringo had ulterior motives (apparently he's buying up sources of fresh water all over South America so he can hold the world to ransom when water starts to run out blah blah blah).
Anyway, Chile wants to continue the Carretera Austral through the park, connecting Puerto Montt with Chaiten eventually. So they presented a plan. Tompkins also presented a plan.
Now, if you were the leader of a third-world developing nation like Chile, you'd think you'd just jump at the chance to do a better project, cheaper. Instead, the government has taken 2 years to study the idea of doing further studies to decide which project to go ahead with. Click on the image below to see the differences in Tompkins' project and that of MOP (Ministerio de Obras Publicas). Then decide which one you'd go for.
