Leaders from 40 states are gathering in London to discuss the illegal wildlife trade. The aim is to draw up a global declaration that will tackle animal trafficking. Prince Charles and The Duke of Cambridge, Prince William, will attend the meeting, hosted by the government.
Conservationists say poaching has reached a crisis point: tens of thousands of elephants, rhinos and tigers are being slaughtered each year. The WWF estimates that the animal black market is worth $19bn (£12bn) a year. Much of the demand comes from Asia, where animal products, such as rhino horns, are used in traditional medicine or are bought by the rich as trophies.
