Organically grown produce isn't necessarily healthier for you. For one thing, it isn't guaranteed to be free of synthetic chemicals, a lot of which are ubiquitous in the environment now and are almost impossible to avoid. In any case, some scientists doubt that the small amounts found in conventionally grown crops are all that dangerous. You also need to consider the big picture. Excess chemical use isn't the only or even the biggest farm problem we've got.
Some people are more worried about soil erosion.
Trouble is, if you don't plow, you need to rely heavily on herbicides to control weeds. Sure, some people claim they can farm organically and conserve soil at the same time. But it's not easy. Not at all. Although organic produce accounts for only 2 percent of crops in the U.S., increasing sales in this category send a powerful signal to the agriculture industry.
