Is ozone a pollutant of the environment or a patron saint of health?

Ozone, the protector of the earth, refers to the ozone that exists in the stratosphere and above the high air, which absorbs most of the short-wave ultraviolet rays, so that all things on the earth can reproduce, and the current pollutant ozone refers to the low altitude produced by human beings, which is destructive due to its strong oxidizing properties and other reasons

Therefore, due to the different locations of their distribution, their identities are also different Everything has two sides Gunpowder can kill people, but it can also benefit mankind, so it cannot be said in general terms whether it is beneficial or harmful

From the title, it is known that 3 liters of oxygen can be converted into 2 liters of ozone, and the volume change is liters to liters, and the volume changes to . From this, it can be seen that there are liters of oxygen to 3 liters of ozone (the volume changes to.

Therefore, there are 3 litres of oxygen and 3 litres of ozone remaining.

I'm sorry, but I don't know what form the added gram oxygen is in the second question.

Caring for the ozone layer requires each of us to take practical actions to reduce or eliminate substances such as CFCs, halons, chlorofluorocarbons (HCFCs), methyl bromide and other substances that are harmful to the ozone layer, because the use of products containing these substances will lead to the depletion of the ozone layer. The following are examples of substances that contain ozone-depleting substances in daily life.

After a long period of struggle and the awakening of human ecological consciousness, the destruction of the ozone layer has now been basically contained. The insatiable demand for nature in the early days also led nature to fight back against humans. Global warming and volcanic eruptions are all the consequences of human beings not living in harmony with nature.

After experiencing these disasters, human beings decided to learn from the pain, and the efforts to stop air pollution were also very strong, so the ozone layer has also been well recuperated.

Nowadays, there is a large ozone hole in the sky over Antarctica, which is caused by excessive pollution of the environment by human beings, so that this hole area is exposed to ultraviolet rays and cannot be protected by the ozone layer.

Decades ago, the ozone layer cavity over both the Antarctic and the Arctic was caused by the use of freons in refrigerators and air conditioners, and then the emission of freons was banned, and now the ozone hole is gradually healing and is expected to heal completely in a few decades.

Today's ozone layer has been destroyed a lot, all of which are the result of our human failure to pay attention to protecting the environment.

Now there are some areas where the ozone layer is a little hollow, which is actually a very dangerous manifestation, because ultraviolet rays can make people cancerous.

Because we emit a lot of carbon dioxide, which has been emitted for hundreds of years, the ozone layer that protects the atmosphere is getting thinner and thinner, and now the ozone layer in our sky has been gone for eight months.

According to reports, September 16 is the International Day for the Protection of the Ozone Layer, and the reason why the protection of the ozone layer is so widely valued worldwide is because ozone is the umbrella of the earth's living systems.

According to the report, Wang Weihe, a researcher at China's National Satellite Meteorological Center, said that ozone is a trace gas naturally existing in the atmosphere, accounting for only about three parts per million of the atmospheric volume, and ozone is the highest concentration near 20-25 kilometers from the ground, forming the so-called "ozone layer".

Experts also said that the ozone layer is not static, in the mid-80s of the 20th century, scientists found that the total amount of atmospheric ozone in the Antarctic region has decreased by 30%-40% compared with 10 years ago, and then an ozone layer hole appears over the Antarctic continent every spring. The thinning trend of the ozone layer, which began around 1970, is related to the emission of ozone-depleting substances from human activities.

Once the ozone layer "umbrella" fails, it will not only pose a serious threat to the earth, but also disrupt the climate balance and lead to frequent extreme weather events.

Why is the ozone layer the "umbrella" of the earth? What happens if you lose it?
