The satellite found that the Alps were turning green. Why? What should humans do? From 65438 to 0984, Swiss scientists took some black and white aerial photos of the Swiss Alps by plane with the most advanced film camera. Since then, scientists have begun to study the changes that have taken place in the Alps. After the earth reconnaissance satellite came out, scientists used it to observe the changes in the Alps for a long time and hoarded a lot of satellite image data.

Many satellite images reveal the gradual changes in the Alps. The satellite images taken by 1998 are obviously different from those taken by 202 1. The Alps in the satellite image of 202 1 are greener, which means that the vegetation on the peaks has obviously increased. The Alps, located in the southeast of Europe, are the most majestic peaks on the European continent. It is about 1 0,200 kilometers long from east to west and 260 kilometers wide from north to south, covering an area of 220,000 hectares, covering a part of Germany, France, Italy, Switzerland, Austria and Slovenia.

The Alps are 3 kilometers above sea level, but there will be 82 peaks over 4 kilometers. Common sense tells us that the higher the altitude, the lower the temperature, which means that many areas of the Alps are covered with snow and ice for a long time, and satellite images also show snow-covered peaks. However, scientific research data show that in the past 38 years, about 80% of the vegetation area in the Alps has significantly increased the total number of vegetation, and the peak snowfall has obviously decreased by about 10%, both increasing and decreasing. Emerald green has increased, while ivory has decreased.

What caused such amazing changes in the Alps? There is only one fundamental reason, that is, the effect of global warming is becoming more and more obvious. With the increase of the global average temperature, the overall environmental temperature of the Alps is still rising, which leads to the melting of snow and the crazy growth of vegetation. As the only beautiful garden of mankind, maintaining the beautiful garden of the earth is what you can do at present. If the environment of the earth's beautiful garden deteriorates, human beings will probably not be able to survive on the earth.

In recent years, everyone is trying to protect the earth and reduce the trend of climate warming, and planting green is one of the countermeasures we often say. Nature's sub-publication, Sustainable Development of Nature, published such a scientific research achievement before: during the period from 2000 to 20 17, the total area of newly-added green vegetation on the earth was basically equivalent to an Amazon rainforest, and the earth became greener and greener. Among them, India has made great contributions, and China and India have each contributed one third to the earth, which is obvious to the people of China.

The earth is getting greener? The communication satellite found that the Alps were changing color, and scientists were extremely worried about it. Their diligence in recent years is obvious to all the world. From the early days of the People's Republic of China to today, it has taken us decades, and the forest coverage rate has increased from the initial 8.6% to 23.04%, and the forest area has increased from more than 80 million hectares to 220 million hectares. According to the plan, by 2025, their forest coverage may increase to 24. 1%.

In addition to maintaining the earth, we also need to explore the universe diligently and find some aliens suitable for everyone's life in the deepest part of the universe. Because the earth is not always livable, with the increase of the temperature and chromaticity of the solar environment, the earth will become hotter and hotter in the future. Scientists predict that after 65.438 billion light years, the earth may not be suitable for resettlement. Therefore, the ultimate development direction of mankind is to go to the stars and the sea and to invest in aliens by immigrants.

At this stage, scientists have seen more than 5,000 exoplanets and selected 24 "super livable" planets from the known exoplanets. The natural conditions of this "super livable" planet are relatively good, the ambient temperature is suitable, and the air contains a lot of oxygen, which should be suitable for human habitation in essence. Some scientists believe that daily life on these "super livable" planets may be more comfortable than on the earth.

However, the distance between this "super livable" planet and our earth is too far. In the near future, no one will be able to reach this "super livable" planet for a long time, so the most important thing now is to maintain the earth, develop science and technology diligently on the premise of protecting the earth, and strive to master the ability of interstellar flight and interstellar immigration as soon as possible.
