On the 12th, the US Space Agency (NASA) excitedly sent a tweet, which was written at the beginning.
NASA is so excited because their satellites have observed that the world has become more and more "green" in the past 20 years.

Another sentence in the article also makes the people feel happy:
"The satellite data from 'NASA Earth' shows that the actions of China and India dominate the earth and turn green!"
Yes, you have not read it wrong. For a long time, China and India, which have been accused by the West for greening problems and environmental pollution problems, have taken off their hats and become the main force in the world's greening operations!
Among them, the increase in vegetation in only one country in China accounts for at least 25% of the total increase in global vegetation over the past 17 years.
In fact, whether it is NASA's excitement or the solid data given by satellite data, the world has once again made the world look at China, and many netizens have said "thank you" to China!
The great contribution of China and India has broken the "intuition" of scientists.
For more information about NASA's announcement, an article on the February 11th issue of the British Nature magazine website gave more detailed evidence.
The article introduces a study by Boston University in the United States: The researchers found the "unexpected joy" by examining the remote sensing data collected by the NASA satellite between 2000 and 2017:
The global green area has risen by 5%, which is equivalent to an additional area of the Amazon rainforest.
What makes a major contribution to this is the leading and promoting role played by China and India.
In the words of Boston University researchers, this is a "surprising" discovery, and NASA's official website reports are more blunt, and the research conclusion is "inconsistent."
Because people often think that a country, especially a developing country, has a large population, which leads to over-exploitation, which in turn degrades green space.
However, the numbers don't lie, and the facts tell these scientists: China and India do spare no effort in greening the planet.
According to Boston University researchers, China and India account for only 9% of the world's land, but contribute up to one-third of the global green area.

In fact, scientists noticed signs of greening in the earth in the mid-1990s, but at the time they only thought that this was due to the increase in carbon dioxide concentration, and it was not clear what humans played.
Now, by analyzing the satellite remote sensing data accumulated over the past 20 years, these researchers can finally determine:
It is the human activities of China and India that have contributed to the increase in global green coverage.
Netizens all over the world are saying "thank you" to China.
So how do China and India “break common sense”?
Scientists believe that the answer is clear, that is, afforestation and agricultural intensification.
According to the data given by the study, 42% of the newly added green area in China comes from afforestation, 32% comes from agriculture, and India's new green area is mainly from agriculture, accounting for 82%.
"China and India have worked together to ensure that the two countries have not only significantly changed the area of arable land, but also ensured the growth of grain output and greatly increased the green area. Since 2000, the production of cereals, vegetables and fruits have been produced. Increased by 35% to 40%," the researchers said.
It is worth mentioning that the scientists who are inspired and shaken by the numbers are not only the scientists involved in the research.
We browsed NASA's social media homepage and found that tweets about the research have won more than 9,000 praises, making it the most popular NASA push.
In the face of the progress made by China and India, countless foreign netizens are even more than their own praise.
Chinese netizens are also very grateful for their gratitude and encouragement from all over the world. Many netizens have “remembered” their own efforts in the greening industry in their comments:
On the 11th, Nature magazine pointed out in another article that the increase in green planting is more evident in China than in India, because China's new greening is mainly based on forests, unlike India, which mainly relies on farmland vegetation.
When it comes to planting trees, you may remember that at the end of last year, China had done a major event that had never been seen before: eradicating the Mu Us Desert.
This desert, which began to form in the Tang Dynasty, has finally been re-applied green after more than a thousand years of "yellowing yellow", and the water and soil are no longer lost, which has reduced the amount of sediment transported by the Yellow River by 400 million tons.
The governance of the Mu Us Desert has even “surged” the United Nations. Some UN officials have commented that the practice of the Mu Us Desert Governance has made things that the world pays tribute to China.
China's achievements provide a model for other countries
In July 2017, the US Time magazine published a video on the video website about China’s practice of managing the Kubuqi Desert. At that time, foreign netizens said in the comments that “the world needs to learn from China”. The Indian netizens even praised China and said, "We are doing the same thing in India."
Today, this prophecy becomes the reality of the "amazing" world.

However, in addition to the excitement, the researchers also pointed out that the increase in green area between China and India is difficult to replace the decline in other regions. Tropical rainforest degradation in Brazil and Indonesia is more serious and has a huge impact on sustainable development and biodiversity.
It is difficult to assert how the future greening trend will change. For example, the increase in India's grain output is mainly caused by groundwater irrigation. If the groundwater is depleted, the trend may change.
However, among these hidden dangers, the researchers also saw some positive signals: "After human beings realize that the problem exists, they will begin to solve this problem."
The study recalled that in the 1970s and 1980s, the vegetation of China and India was severely damaged. However, in the 1990s, the two countries began to increase the intensity of environmental issues, so the situation has improved.
From this perspective, today's Brazil and Indonesia may be yesterday's China and India.
"Human adjustment and adaptability is very strong, which is the conclusion we draw from satellite data," the researchers said.
In the eyes of many netizens, the achievement of "the earth becomes green" is inseparable from the fact that "green mountains and green mountains are the Jinshan Yinshan" practiced by China with actual actions, which shows China's great powers.
