Feeding the ten billion: plants and population growth

Abstract

Avillage dies every week in Zimbabwe, where one in five adults suffers from HIV/AIDS, the sexuallytransmitted disease that strips the body of its immunity to infection.Each week, one thousand Zimbabweans die from AIDSinduced illnesses.More than two-thirds of all new AIDS cases in the world are reported from Africa, where more than 21 million people suffer.Across the developing world, which has 85% of all AIDS cases, the struggle against its spread receives a tiny portion-estimated at one-tenth-of the $2 billion that the world spends on HIV/AIDS prevention.
