My idea, is to put the loto winnings into owning a company that would reclaim businesses buildings (ex Detroit) or just floors of the buildings (ex Calgary) that have been desolate and abandoned from industry’s going under from the down turn of the economy and turn them into indoor gardens. These gardens would grow food, of all types (because they are indoor you can control weather). Turning a profit on the goods produced, while giving jobs to the local populous of the struggling area, and taking areas of the city which may never be as full again, and filling it. All this while doing something sustainable for the world and city you are reclaiming.
