By 2030, when today’s toddlers have toddlers of their own, 8.3 billion people will walk the Earth; to feed them, the UN Food and Agriculture Organization estimates, farmers will have to grow almost 30 percent more grain than they do now.

“With eight billion people, we’re going to have to start getting interested in soil,” he said. “We’re simply not going to be able to keep treating it like dirt.”

“We can tell you right now, there is no worry for your health as a result of eating vegetables from this soil,” Monique Beausoleil, a toxicologist with the department — She explained that most of the contaminants were found in soil lower than the roots that most typical vegetables grow, so their absorption rate was very low.”

This system of land use has been called by Binns et al (2003), by the name urban and peri-urban agriculture (UPA).”
