| Senegalese President Abdoulaye Wade has urged world leaders to declare war on locusts that destroy vital crops in poor African states. In a letter to leaders of the ’Group of Eight’ major powers, President Wade said plagues of locusts expose hundreds of millions of people to the risk of hunger or famine. The United Nations Food and Agriculture Agency said last week that West Africa is facing its most serious threat from desert locusts in 15 years. President Wade said locusts’ capacity for destruction of human lives "is far greater than the worst conflicts". |
