Need, greed and ignorance

"To keep up with the growth in human population, more food will have to be produced worldwide over the next 50 years than has been during the past 10,000 years combined, the experts said.

"You can sum it up as need, greed and ignorance," said Andrew Campbell, an Australian environmental consultant. "Some pressures on soil resources come from simple human needs, where people don't have any option but to grow crops or farm animals. But in other instances world markets demand produce, so farmers try to meet those markets. And sometimes, there will be land that's cleared that should not have been, or grazed when it shouldn't have been. All these place great pressures on soil resources." (Thanks Rania)
