Genetically engineered food crops not a solution

Genetically engineered food crops more harm than good

The life-science companies tout the new genetically engineered food crops as a solution. But these crops, too, require large inputs of energy, especially in the form of petrochemical fertilizers. Scientists have thus far been unsuccessful at creating biotech crops that get their own nitrogen from the air rather than from the soil. And studies show contradictory results in terms of yield performance. The future prospects for agriculture look even bleaker when we consider the fact that 11 percent of the land surface on the planet is already used to produce food, which leaves little decent land left for agriculture. In desperation, human beings have began to cut down large swaths of tropical rain forest in the Amazon and elsewhere to make room for agricultural production. The destruction of the rain forest eliminates precious habitat for many of the Earth's remaining species of plant and animal life. The soil base itself is too thin to support food production for more than a few years. The result is spreading erosion and barren land, no longer fit for human, animal, or plant habitation.
