Cecil the lion: 'He died for a cause'

The global outcry following the brutal killing of a lion in Zimbabwe was unprecedented. But the death of Cecil raised more than $1m in donations - and has ensured the survival of his grand-cubs

'Cecil didn't die for a reason. He died for a cause," says Johnny Rodrigues, chair of the Zimbabwe Conservation Task Force.

Five months after Zimbabwe's most famous lion was found skinned and headless on the edge of Hwange National Park, the killers have not been convicted. In October, the Zimbabwean government dropped charges against Walter Palmer, the Minnesotan dentist who paid 35,000 to hunt the lion. Meanwhile the trial of Theo Bronkhurst, the professional hunter who led the expedition, is ongoing.
