Population Growth Is a Threat. But It Pales Against the Greed of the Rich

I cannot avoid the subject any longer. Almost every day I receive a clutch of emails about it, asking the same question. A frightening new report has just pushed it up the political agenda: for the first time the World Food Programme is struggling to find the supplies it needs for emergency famine relief. So why, like most environmentalists, won't I mention the p-word? According to its most vociferous proponents (Paul and Anne Ehrlich), population is "our number one environmental problem". But most greens will not discuss it.
