The ozone layer is the protective covering around the earth. It is a natural layer of gas in the atmosphere that protects us and all living things from the Sun’s harmful and strong ultraviolet radiation. Not only does this harmful radiation causes damage to human health, but also it results in damaging other life-forms. It can affect and alter the terrestrial and water ecosystems. It could alter growth, food chains and life cycles. With harmful UV rays penetrating all around us, it would damage crops, increase health problems and make crucial changes in all life-forms across the planet.
