As the ozone layer gets deteriorated the harmful UV rays will reach the ground and cause various adverse effects.
I. Effect On Human Health
i) The UV- Rays damage genetic material in the skin cells which cause skin cancer.
ii) For the fair skinned people life long exposure to the high level radiation of UV rays increases the risk of non - melanin skin cancer.
iii) Prolonged human exposure to Uv-rays may lead to slow blindness called actinic keratitis. Enhanced level of UV ray could lead to more people suffering from cataracts.
iv) Human Exposure to UV- rays can suppress the Immune responses in humans and animals. It also reduces human resistivity leading to number of diseases such as cancer, allergies and some other infectious diseases.
II) Effect on Aquatic Systems
i) UV Rays directly affect the aquatic forms such as phytoplankton, fish, larval crabs.
ii) The phytoplankton consumes large amount of CO2.
Decrease in population of phytoplankton could have more amount of Co2 in the atmosphere which contributes to the global warming.
III) Effect on Materials
Degradation of paints, plastics and other polymeric material will result in economic loss due to effects of UV radiation.
IV) Effect on Climate
The ozone depleting chemicals can contribute to the global warming i.e, increasing the average temperature of the earth's surface.
