The ozone layer absorbs 93-99% of harmful ultraviolet (UV) light from the sun, protecting life on Earth. Over 91% of the ozone is found in the stratosphere. UV radiation can cause sunburn, skin cancer, eye disease, and weaken the immune system. With decreasing ozone levels over New Zealand since the 1970s, and the country's lack of air pollution to block UV rays, New Zealanders receive more UV exposure. This increases health risks like skin cancer, so it is important to take precautions like applying sunscreen, wearing protective clothing and hats, and limiting time in the sun during peak UV hours.

1. The Ozone Layer By SambitPatra

2. Introduction The Ozone Layer is the layer of ozone (O3) that shields earth from harmful ultraviolet (UV) light. The Ozone layer absorbs 93-99% of the sun’s UV light which is harmful to the life on earth. Over 91% of the ozone in the earth’s atmosphere is in the stratosphere.

4. Ultraviolet radiation (UVR) is made up of three parts: UVA, UVB and UVC. UVR is known to cause sunburn, skin cancer and eye disease. It can also affect the body’s immune system.

6. Our smog free air means there is less pollution to block the UVR.

8. Health Problems The attention that has been given to the gap in the ozone layer has highlighted the increase in health problems involving the ozone layer, such as skin cancer. With less ozone in the atmosphere the amount of UVR rays will increase . This will increase the chances of sunburn, skin cancer and eye diseases. It is best to protect our skin during daylight saving months. Spending less time in the sun from 11am-4pm can reduce UVR exposure by up to 60%.

10. We should take much care about how we are going to tackle this problem like putting on sunscreen, wearing a hat etc.
