People assume that famines are caused by a poor growing season. This is true in agrarian societies where everyone farms. However, a financial world banking catastrophe could lead to the same result; where starvation occurs from lack of funds to purchase food. Also, we may be fast approaching a limit where food production can’t keep up with the increased population. War in the Middle East, is curbing a lot of farm production, which is leading to starvation for many.
And then there is global warming. Once the North polar ice cap melts, the Gulf Stream ocean current could change its direction a tad, making Eastern Europe too cold for food cultivation.
A famine could affect a large part of the world’s population. We are at a point now, where bad weather, financial instability or political instability, could determine who will live or die. A nuclear skirmish in a quest to grab resources, could make food very scarce in some areas.
The next famine will not be anticipated. It may be an economic or financial disaster that triggers it. When it happens, the logistics of transporting food to those that need it could be very hard to accomplish. Imagine a high-density population area like India, where many are already at starvation levels and barely surviving. This could be the end of the road for them.
Without the means to purchase food, life is a real struggle. Most of us are not in a position to grow and produce the food we need; we pay others to provide it to us. Those in the third world who are starving to death slowly, could be the medium for new super diseases that the rest of the world will have to deal with in the future. It is this group, with very weakened immune systems, that could be the incubator for a future plague far worse than any war imaginable.
The funny thing is, the third world was our source of cheap labor. As our economy slows down, the funds that made life possible for them will disappear. That thought worries me. A hungry mountain lion is not going to knock on your door and bargain with you over the price of its next meal -- your pet dog in the back yard.
