Is a Madagascan mine the first to offset its destruction of rainforest?

It’s the first of its kind. Researchers say the island’s biggest mine is on track to achieve no net loss of forest, but there remain important caveats. In this exploration of biodiversity offsetting, Patrick Greenfield examines how pristine rainforest was destroyed to make way for the mine but how scientists now believe that enough forest is being saved to offset this initial clearance.
