w> We reolved the famine problems long ago.CBW> As far as I know, there are people who are still dying everyday due to famine. There's one currently in North Korea. So, it hasn't been resolved.The question of whether there's enough food is a complex one. The famine in Korea is politically-caused. If the wanted to, they could get enough food from South Korea and other sources to feed their population.Africa has has more serious problem, because for various reasons, some nations can't grow or raise enough food to sustain themselves. But Pope John Paul II implied a while back, there is enough food in the world to feed everyone; the problem is a matter of distribution. What the Pope didn't understand is that the political problems will go on into the indefinite future, and meanwhile, many people will starve.The amount of money the U.S. is spending on the Iraq war ($100 million a year, currently, without counting extra expenses, like the billions per year it will cost for wounded soldier's life-long medical care) could go a long way to addressing the world's famine problem. Many "pro-lifers", like the U.S. president, have other priorities, though.But the problem is not as simple as a question of redistribution. In order to make modern, huge-scale farming practical, popular grains have been hybridized, and choices have narrowed. Since there is so little (and diminishing) diversity among crops, humans have become more vulnerable to the effects of pestilence. In response, the grain companies have developed, through genetic engineering, strains that produce their own insecticide. Who knows what long-term effect that will have on people?Besides shrinking in the number of available strains, the human diet is also shrinking in the number of species eaten. We are omnivores, and will not be healthy just eating bread, rice, and meat (where available). And fruits and vegetables may be diminished in nutritional value when they are bred to ship well, rather than to taste good.So, the problem is that it is very difficult to supply a nutritional diet to people when the population is very large. That applies to affluent nations as well, especially if their population is spread out, and especially if they have no tradition of "eating right".I didn't even talk about the problem of soil getting exhausted, and having to use huge amounts of petroleum-based fertilizer due to modern farming methods and the pollution that large-scale farming and agriculture causes. Also, as the climate warms up, Canada will be sitting pretty agriculturally (while losing coastal areas), but many densely-populated areas of the world (e.g., Bangladesh, northern and central Africa) will suffer terrible famines and floods.The big problem, however, may turn out to be water shortages. In some places, ancient aquifers are being drained, and they may take scores of millenia to refill. In parts of India, they're drilling deeper and deeper. What happens when large areas have to truck in their water?All of those things are bound to lead to political instability and wars. The question of disease (in humans, livestock, and the plants and grains they live on) is an open one, but statistically, pestilence and pandemic disease happens. It's all exacerbated by having a large human population.[Fixed a tag - Ineligible]
