OZONE LAYER

This essay will explain the importance of the ozone layer on the health of New Zealand society. It will talk about the relevant issues in the political and social setting and give details on the way of resolving the problem. Furthermore, it will include my personal view for the solution to this topic. The ozone layer is situated in the upper atmosphere, about 15 to 50 kilometres above the earth’s surface. It is extremely important for human existence, plants growth and for survival of all living things on the earth (Ministry for the Environment [MFE], 2008). This ozone layer serves as a protection or defence against sun’s harmful rays and decreases the amount of dangerous ultraviolet radiation. Excessive ultraviolet radiation can cause sunburn, skin cancer and cataracts in humans and can affect the body’s immune system too (Cancer Society of New Zealand, 2005). It would also give an adverse effect to plant growth and marine environment (MFE, 2008). New Zealanders in general are sports loving people. They are enthusiastic in playing sports like rowing, rugby, soccer and cricket. They also like to walk, run and swim under the heat of the sun. It gives them satisfaction and joy, and it provides the need of their body to be physically fit. However, enjoying the heat of the sun has now become dangerous if not properly observed due to the effect of harmful ultraviolet radiation. For the last 30 years, it is believed that ozone levels over Antarctica have lessened by nearly sixty percent during the spring season and a hole in the ozone layer is obvious and can be detected by satellite. When the ozone hole splits up, the ozone-depleted air moves in the southern hemisphere where New Zealand is situated (MFE, 2009). Depleting of the ozone layer has significant impact on the health of New Zealand people. According to Ministry of Health (2009), melanoma of the skin was the fourth most common cancer diagnosed in New Zealand which...
