Every dollar in a market is in competition with every other dollar in that market. Just adding money to the market will mostly jack up the prices. Spend that money to: 1) clear a nuisance; 2)harvest biomass, some of which is fit for human consumption. Africa has aquatic weed infestations from end to end. A large amount is fit for human consumption. A large amount is not, and can only be used for fuel. The plants that clog your waterways are the ones that tolerate wastes, and they collect and hoard them like misers. Mild cleansing will usually render contaminated plants fit for consumption by yeast, but not people. With this you can attack the food crisis, the fuel crisis, malaria, drought, flooding, and desertification all at once. And the labor to do it is available and hungry for work.
