Scientists talk about the formation of a drinking water shortage on Earth

American scientists from the Rensselaer Polytechnic Institute were able to register a decrease in oxygen levels in freshwater lakes. According to experts, this phenomenon is caused by the acceleration of global warming on Earth.

According to the scientific papers published in the journal Nature on June 2, the experts studied 393 reservoirs, most of which are located in temperate latitudes. The study took into account work from 1941 to 2017.

It found that lakes lose oxygen 2.75 to 9.3 times faster than the world’s oceans, which negatively affects their ecosystems.

The study found that since 1980, the oxygen content of water bodies has decreased by 5.5 percent at the surface and 18.6 percent at the bottom. The scientists attributed the decrease to a 0.38-degree rise in fresh water temperature over 10 years.

Due to climate change, blue-green algae began to multiply in the lakes, detrimental to organisms living in fresh water.

Methane produced by anaerobic bacteria under such conditions increases greenhouse gas emissions, which only accelerates the rate of climate change.

Thus, experts have concluded that warming can lead to the depletion of the Earth’s drinking water reserves, as well as an imbalance of freshwater ecosystems.
