Prince Charles and his two sons, Prince William and Prince Harry, are joining forces with 50 world leaders to fight against poachers who slaughter African elephants for their in demand tusks.

"There's not a moment to lose if we are to save the species," Prince Charles said during a meeting that included Canada's Foreign Affairs Minister John Baird.

The conference was held in London and aims to strengthen law enforcement response to poaching and lessen demand for illegally obtained ivory, which has been growing especially within Asia.

Currently, poachers kill up to 60 African elephants a day for their tusks, and herds have diminished by about two-thirds in the past decade.

"We need to tackle wildlife crime with a concerted global response as vigorous and forceful as the trade itself," said Prince William.

He and his father, Prince Charles, released a video ahead of the conference calling for worldwide support in their campaign against poaching.
