Supersonic jet planes, hair spray, aerosol insecticides. What do they have in common? We use them for completely different purposes. But they have a dangerous common effect. They damage the ozone layer of the atmosphere.
We talk a lot about the various forms of pollution: air pollution, water pollution, noise pollution, radioactive contamination, etc. but we don´t hear much about the damage to the ozone layer of the atmosphere.
Ozone is a gas. It has three atoms of oxygen per molecule of gas. But it is not a stable gas. When ozone is in contact with other gases, it gives one of its oxygen atoms to them. Then, it becomes ordinary oxygen. That is exactly where the problem begins.
The layer of ozone in the atmosphere is approximately 15 to 30 miles above the earth. It filters the sunlight and absorbs much 0f the ultraviolet radiation. In short, it protects us from the ultraviolet radiation of the sun.
When ozone becomes oxygen, there is little protection against ultraviolet radiation. Oxygen dos not block this type of radiation and we are consequently exposed to it. This radiation causes many types of skin cancer in man. It also affects plant and sea life.
Evidently, technology brings us comfort and progress. But the price is very high – it is destroying our environment. It makes our world more comfortable, but it also damages it; this is a serious problem and we have to face it.
