The Effect Ultraviolet Light Has On Life Forms
-Ultraviolet light is given off by the sun and is usually blocked about 97% of the time by the ozone layer. In the past 20 to 30 years, the ozone layer has weakened resulting in more and more UV rays reaching the earth’s surface. This means more animals, plants, and humans will be negatively harmed. In humans and some animals, too much exposure to ultraviolet light can lead to injuries in the eyes, skin, and immune system. Diseases like skin cancer, cataracts, and sun burns can occur in humans from taking in too much UV light. In plants, too much UV light can lead to less crop production and can even kill certain plants. To prevent too much UV light form making it all the way to earth’s surface, we need to protect the ozone layer to block the harmful rays.
