Damming contributes to global warming

Research results have been published in the Journal of Science, Technology and Environment (Germany) showed that the construction of dams on rivers and lakes, or in entertainment areas contributes to making the temperature of the Earth rise higher than the projected level. guessed before.

Andreas Maeck, a senior student at Koblenz University in Germany, gradually started a group of students, studying the amount of methane (methane) emitted from small dams containing water below 15 meters deep. Research shows that when dams operate, countless bubbles from settling organic matter will be generated. These water bubbles are the source of the huge amount of methane in the air.

The team stressed that the hydroelectric dams could generate up to 7% of methane, much higher than previously announced. There are currently about 50,000 large dams in the world in operation, this will be the 'source of production' of extremely large greenhouse gases. According to scientists, methane gas has the ability to increase the temperature 25 times higher than carbon dioxide gas (C0 ₂ ).

Experts warn that this leading greenhouse gas is increasing as the construction of dams becomes popular in many countries around the world to create new energy sources for life. people and production activities.
