The Dhaka Times Desk About two billion trees were found in the dusty desert of the Sahara! Scientists have given this information by analyzing the images obtained from satellites.
This discovery will especially help the research of ecologists. The calculation of how much carbon is accumulating around the world will be more accurate.
Professor of Geology at the University of Copenhagen, Martin Brandt, who led the research team, told the news agency, naturally, they were very surprised. They never knew that so many trees grow in the Sahara. There are also very rough areas with no vegetation in this desert, but the amazing thing is that trees are growing even under the sand.
US space research agency National Aeronautics and Space Administration, aka NASA scientist Jess Meyer, said that this information is very important in protecting the environment and preventing climate change. After the next 1, 2 or 10 years, if you analyze the satellite images again, you will be able to catch the change.
It is not an easy task to find greenery in the vast desert, and even for satellites to measure the increase or decrease in the number of trees requires a lot of effort. That's why Martin Brand and his whole team had to get up to speed to make this almost impossible task possible. 90 thousand trees have been identified by the brand itself. Brand also emphasized the classification of plants. For that, the research team is trained separately.
Another study examined 11,000 images covering an area of 500,000 square miles. The results of the study were published in the journal Nature. There is also an indication of this vast existence of green in the Sahara.
Many people see an important role behind this in the gradually changing climate of the world. It is precisely for this reason that many green plants are born in the cold chest of the ice-covered Antarctica!
