A man who led a successful campaign to stop a mega-dam being built in Borneo's rainforest has been awarded a top environmental prize.

Peter Kallang spent years raising awareness of the plans among indigenous communities in the Malaysian state of Sarawak, and the wider world.

After a five year campaign the government eventually cancelled the project.

Peter has now been honoured with the 2019 Seacology Prize which is awarded to people for protecting island environments.
