I'll start: Leaving the world a better place

Acquire currency to pursue my dream to build a sustainable area with beneficial plants and animals (fruits/chickens), solar panels, isolated glass, water reservoirs, roof with natural isolation, inside clean air plants & fun inside (game/cinema). House doesn't need to be that big - just enough - also in regards to easy cleaning. Good sustainable basis for individual household (say 80%) and 100% sustainable as a community.
