Answer: Harmful effect on immunity, sunburns and skin cancer.
Explanation: Ultraviolet rays come from solar radiation and thanks to the atmosphere, this amount of UV light is as much as it needs the earth, because a small amount besides the harmful ones also has positive effects on life on earth. However, due to damage to the Earth's protective atmospheric coating, the amount of UV rays increases and adversely affects human health, primarily on the immune system, increased intense sunburn, skin cancer. Due to the increase in UV rays, there is relatively little time spent in the sun to get very dangerous sunburns, which can lead to skin cancer. Once before, exposure to the sun in the same time period was even medicinal and desirable from time to time, but the increase in UV rays has dramatically changed. According to scientists, excessive exposure to the sun and increased UV radiation leads to the redistribution of white blood cells, which affects the decline in immunity.
