40 billion each year to end global hunger by 2030. Everyone is everyone in the whole world. These figures are from the Un food programme’s. Population would not explode, because malthusian economics are for eco fascists. Rich people that have no food insecurity have Less kids, not more. See all of Europe and the US and many other countries as examples. Human population is not the graph about wolves and deer you saw in 10th grade biology.
