In a small farmhouse surrounded by cloud forest, Ivan Lozano inspects dozens of glass containers that hold some of the world's most coveted frogs.
The conservationist has been fighting the illegal trade in rare tropical frogs for years, risking his life to save the brightly coloured, poisonous amphibians whose population in the wild is dwindling.
But Lozano doesn't hunt down poachers and smugglers. He's trying to undermine them by breeding exotic frogs legally and selling them at lower prices than specimens plucked by traffickers from Colombia's jungles. His frog-breeding centre, Treasures of Colombia, is among a handful of programmes around the world that are trying to curtail the trafficking of wild animals by providing a more eco-friendly alternative: specimens bred in captivity.
"We can't control the fact that in some countries it is legal to own these animals," Lozano said.
"But we want to make sure that collectors buy animals that are raised in captivity and are legally exported," he said.
