Environmentalists blame human activity for the conditions in Russia’s Lake Baikal and are calling for the amount of chemicals dumped into it to be reduced.

Hot, dry summers and deforestation are also said to have contributed to low water levels.

Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape with a surface area of 31,722 km2 (12,248 sq mi). Baikal is home to more than 1,700 species of plants and animals, two-thirds of which can be found nowhere else in the world.
