Hydroculture
The world is in the middle of a food crisis. Opinions differ as to its severity, but most accept that the crisis is real and potentially poses a major threat to the health and food supply of a large proportion of the global population.

Simply put, a number of previously productive agricultural regions are no longer as fertile as they once were because of the weather. And second, many farmers have found that they can get a better return growing biofuels than raising crops. As a result, large areas of valuable cropland are no longer being used for this end. Conventional agriculture is ill-suited to solve the food crisis, but hydroculture might be a potential solution.
