I had studied many of the effects that global warming produces; but never the food issue. Global warming will affect all the world but specially places in the tropics and subtropics, because the crops produced there are less able to adapt. “Scientists at Stanford University and the University of Washington, who worked on the study, discovered that by 2100 there is a 90 percent chance that the coolest temperatures in the tropics during the growing season will be higher than the hottest temperatures recorded in those regions through 2006.”
These countries in the tropics or subtropics would produce 20 to 40 percent less crops than now, this would make that half of the population experience a food shortage.
By the end of this century, population is expected to double. This means that food production should double too in order to be able to provide enough food for the population. But the problem we’re going to face is that the increase in temperature will make food production harder. Until it will be almost impossible to feed all the humans on earth.
