Effects of the Ozone Hole Thinning of ozone layer means getting direct in touch with ultra violet rays which can cause skin cancer or skin irritation which can lead to death. A decrease in 1% of ozone layer can cause 5% increase in cases of skin cancer. Exposure to UV rays has also increased the cases of cataracts which in turn affects people's vision and could also cause an increase in people becoming blind Depletion of ozone layer and increase in UV rays can also cause DNA damage which can also be catastrophic. Climate change affect natural disasters: With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapor is evaporated into the atmosphere it becomes fuel for more powerful storms to develop
