Volunteers riding in kayaks take part in a water-waste removal and cleanup campaign in the Nile river off the island of Manial in Egypt's capital Cairo on March 7, 2020. 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.
