The father and son duo, Leo and Stefan Pröstler, are working in Costa Rica to preserve some of the country's stunning and threatened biodiversity by planting mixed forests. Financed by investors around the world, the project focuses on planting endangered and forgotten tree species. The new forest is providing a habitat for various species of plants and animals as well as proving a source of income for local farmers. By planting ginger, for instance, between the trees, the farmers are helping to improve the soil and they can export the crop to Germany once it's harvested. For investors, the project is lucrative. But they'll only see returns once the trees are chopped, sold and planted anew.
