How did NASA save people from the 'end of the world'?

NASA actually saved people from the apocalypse in the 1980s. If they didn't quickly realize the big problem in our atmosphere, life on Earth would collapse in 2065.

According to the insider sheet, the early 1980s were a memorable time. At that time scientists were so frightened that they believed that if there was nothing to stop, the world would face a tragedy in 2065: all plants died, animals had no children, aquaculture failed, billions High rates of cancer, high temperatures in Washington DC will cause serious sunburn.

A group of scientists from NASA and the British Antarctic Survey Team discovered that a portion of the ozone layer in Antarctica was seriously destroyed . It can cause the ozone layer in this area to become extremely thin.

Without ozone, ultraviolet rays hit the surface, we will get skin cancer, the plant will die.

Meanwhile, the ozone layer is the area in the stratosphere that absorbs harmful UV rays from the sun, which is the natural sunscreen for the Earth. Around that time, ozone concentrations decreased by 67%. Thankfully NASA has a pretty good idea of ​​what is going on.

Scientists quickly found the culprit and raised a warning bell about CFC toxic chemicals . They are popular in products such as sprays, refrigerators, they are easily selected in many uses because they are not toxic to humans directly but are extremely toxic to the ozone layer.

If the amount of CFC continues to be uncontrolled, not only the ozone layer in the cold region is affected but also in other regions. It is estimated that about 17% will appear worldwide by 2020, a hole in the same ozone layer will form in the Arctic. By 2040, 70% of the ozone layer will likely disappear. By 2050, the tropics will lose the ozone layer completely.

Without ozone, ultraviolet rays hit the surface, we will get skin cancer, we will get cataracts in the eyes, animals will get cataracts, plants die.

Luckily, policy makers listened to the scientific world and they acted. The Montreal Protocol was signed in 1987, reducing harmful CFCs. By 1996, CFC was completely banned in developed countries.

And today, satellite data Now indicates that ozone holes are in the process of healing. And if we continue to hold it, it can be completely healed at the end of this century.
