What good will it do?

Plans to use a state-of-the-art camera onboard a satellite to monitor deforestation levels in Africa's Congo Basin have been unveiled.
The high resolution RALCam3 camera, designed and built by UK scientists, will provide the first detailed view of the area's rate of forest cover loss.
The project is part of the Congo Basin Forest Fund, a £108m joint-initiative by the UK and Norwegian governments.
The fund aims to curb climate change by preventing deforestation in the region.
