TOPSHOT - Volunteers rake the Nile river water off the shore of the island of Manial in Egypt's capital Cairo on March 7, 2020 as they take part in a water-waste removal and cleanup campaign. - Early one morning in Cairo, a flotilla of some 300 environmental determined activists paddle their kayaks across the Nile, fishing out garbage from the mighty waterway that gave birth to Egyptian civilisation but now faces multiple threats. In the past three years they say they have picked some 37 tonnes of cans, plastic bottles, disposable bags and other trash from the waters and shores along the Nile in Egypt. The river, Egypt's lifeline since Pharaonic days and the source of 97 percent of its water, is under massive strain from pollution and climate change and now the threat of a colossal dam being built far upstream in Ethiopia.
