Focal Point travels to Angola’s remote central highlands to meet people living on the frontlines of climate change. Correspondent Randolph Nogel embeds with The HALO Trust, an international charity working to remove hundreds of landmine fields, a vestige of Angola’s civil war. The humanitarian effort is also an environmental one, as the Angolan highlands, known locally as ‘the source of life’, are an essential water resource and ecological pulse for the entire region.
