Detailed explanation-1: -A diminished ozone layer allows more UV radiation to reach the Earth’s surface. For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain.

Detailed explanation-2: -Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems. Too much exposure to UV is believed to be contributing to the increase in melanoma, the most fatal of all skin cancers.

Detailed explanation-3: -Plants are harmed by ozone, which enters leaf holes known as stomata and oxidises (burns) plant tissue during respiration. It may result in reduction in plant development, decreased leaf size, blooming, and photosynthesis in plants, as well as lower-quality human harvests.

Detailed explanation-4: -Under high Photosynthetic active radiation, UV-B light increases the net plant photosynthesis in several plant species. Higher production of flavonoids can be induced under both UV-B and high PAR in young and old plant leaves. UV-A radiation has a positive effect on the photosynthesis when plants are exposed to UV-B.

Detailed explanation-5: -Scientists have confirmed that non-melanoma skin cancer is caused by UV-B radiation, and further believe that a sustained 10% depletion of the ozone layer would lead to a 26% percent increase in non-melanoma skin cancer. This could mean an additional 300, 000 cases per year world wide.
