Can the world feed 10 billion people?

Already, one-third of children in Niger are malnourished, and global warming will further undermine agricultural output in the desertifying Sahel. Even if the current birth rate is halved by 2050, the population will still explode — from 14 million today to 53 million by 2050. If the birth rate continues at current levels, the population could reach a totally unsustainable 80 million. Unless there is an immediate commitment to family planning, the scale of human suffering over the next three decades in the Sahel could equal or exceed that caused by HIV/AIDS in the past 30 years.
