There are so many helpful things we could do for our planet which aren't even truly disruptive to our economies which we neglect to do for either inertia sake or the profit of existing archaic industries...
Take for example ditching most of our usage of fossil fuels, we have nuclear and other technologies but it would be greatly destabilizing to economies dependent on selling oil. Considering the environmental catastrophe we already face and will face from global warming it's no brainer!
What about protecting important old growth forests? They are a bastion of biodiversity and important for sequestering carbon but since the lumbar shortage drove up the price of wood the importance (not to mention the fact a majority of people don't want that lumber cut) we're going ahead anyways. Check out sales in Alaska and Canada.
In short, what would this be used for? I imagine what ever seems entertaining and marketable which will just get us further from saving ourselves and the planet...
