In the near future, the city can turn into a jungle
A group of scientists argues that contrary to common belief, the area of green space on our planet is constantly increasing.
This year in the popular journal Nature published a scientific article in which experts have proven the increase in vegetation cover of the planet is 7.1%. These findings completely contradict the theory, supposedly the forest has been dramatically reduced.
To conduct the study, scientists have perfected the radiometer AVHRR, which collected all the data of the last 35 years. In addition, experts have developed a scale that reflects the level of vegetation cover. The logarithmic factor VCF has three of the spectrum: TC (forest and jungle), SV (low grass, shrubs) and BG (vegetation absent).
From the above chart it is evident that over the last 35 years the forest area increased by 2.24 million km2. Today, forests are dying in the region of the tropics, whereas in middle and Northern latitudes to slowly but surely grow.
Scientists said that the observation of vegetation was carried out daily. This implies that the satellite supposedly flies 35th year. And then what year was it update? Perhaps the experts relied on data for the last 10 years, and the rest of the information taken from the archives.
It is also important to note that in Africa and Brazil, forests are dying at an incredible rate. Therefore, in our latitudes, forest cover increased by 7.1%, and 15-20%.
In most regions of Asia supposedly there is degradation of plants (cover has decreased by 1.16 million km2). In fact, the vegetation thrives there, this can be confirmed by gardeners and farmers.
