The partial destruction of the Kakhovka dam in southern Ukraine has worried many environmental groups. A wave of 18 billion litres of water has hit fertile land in the country, and several animal species are threatened by rising sea levels.
150 tons of motor oil have already been spilled into the Dnieper River and the pollution is likely to spread over more than 5,000 km2 and as far as the Black Sea. A zoo was submerged by the waves: 300 animals died, drowned locked in their cage.
