1, increasing the risk of skin cancer: ultraviolet rays are the main cause of skin cancer. The hole in the ozone layer makes more ultraviolet rays penetrate the atmosphere, which increases people's exposure to ultraviolet rays, thus increasing the risk of skin cancer. Ultraviolet rays that affect the immune system will destroy the immune system of the human body and make people more susceptible to illness.
2, affecting eye health: excessive ultraviolet rays can cause eye diseases such as cataracts. Ultraviolet rays that affect biodiversity are fatal to marine and terrestrial organisms, and the hole in the ozone layer may lead to the decrease of biodiversity. Protecting the ozone layer and reducing greenhouse gas emissions are important tasks that each of us should pay attention to and participate in.
3. The formation of ozone hole is mainly due to the massive emission of man-made gases such as chlorofluorocarbons (CFCs) and haloalkanes produced by human activities. The hole in the ozone layer has many effects on human health, so it is very important for people to protect the ozone layer.
Information about the ozone layer
1. The ozone layer is in the middle and lower stratosphere of the atmosphere, and there is a banded region around the earth about 20 to 30 kilometers from the ground, which is the ozone layer. For protection, the ozone layer can absorb ultraviolet rays with wavelength below 306.3μm in sunlight, and protect people, animals and plants on the earth from short-wave ultraviolet rays.
2. Heating: Ozone absorbs ultraviolet rays from the sun and converts them into heat energy to heat the atmosphere. Because of this effect, there is a warming layer above the earth 15 ~ 50 km, which is the place with the highest stratospheric ozone concentration. The role of greenhouse gases is equally important in the upper troposphere and the bottom of the stratosphere, that is, at this very low temperature height.
3. Some pollutants emitted by human production and living activities, such as chlorofluorocarbons and other widely used bromides contained in refrigerants of refrigerators, air conditioners and other equipment, will decompose when exposed to short-wave ultraviolet rays, releasing chlorine atoms or bromine atoms, and these free radicals will react chemically with ozone, turning ozone into oxygen molecules and oxygen atoms.
