Poaching in Africa has rocketed in the past five years in the face of soaring demand in the Far East for ivory and rhino horn, according to the World Wildlife Fund.
Businesswoman and entrepreneur Deborah Meaden said: "This has got to stop. On my watch - in my lifetime - we cannot see these animals disappear."
"In our lifetime we could lose elephants in the wild. We could lose rhinos in the wild.
"What is probably less understood is that we know where the money comes from, but where is it going? Often it will be fuelling war and conflict."
