Aral Sea, between Uzbekistan and Kazakhstan

In the 1960s the Soviet authorities undertook a plan to clear the arid plains of Kazakhstan, Uzbekistan and Turkmenistan.

The two largest rivers in the region, Syr Darya and Amu Darya, whose flows fed the snow and rain in the Tian Shan Mountains, were used so that cotton and other crops could be grown in the deserts.

The rivers flowed through the Kyzylkum desert and emptied into the Aral Sea, which was previously the fourth largest lake in the world and which today has almost completely disappeared.

West Virginia, USA

The state of Rondonia, in western Brazil, covered 208,000 square kilometers of forest, but today it is one of the most deforested areas in the Amazon.

During the last three decades 67,764 kilometers of rainforest have been depleted.

Beneath the forested mountains of the Appalachians in West Virginia, there are deposits of coal.

To extract the coal, extraction companies build large surface mines.

Images from Boone County show why this controversial method is also known as "destruction of mountains".

Ozone layer

The ozone layer in the stratosphere protects the Earth by absorbing ultraviolet rays that damage the DNA of living things and can cause skin cancer.

In the 1980s scientists noticed that the protective layer was rapidly disappearing over the South Pole.

Temperature anomalies The world is warming up. According to the temperature analysis of the Goddard Institute for Space Studies, the global mean temperature on Earth has risen by 0.8 ° C since 1880. Two-thirds of the warming was recorded after 1975 from 0.15 to 0.20 ° C in each decade.
