This image shows a factory contaminating the air and polluting it. Air pollution has caused a hole in our planet’s ozone layer. The ozone layer is what protects us from the sun’s harsh UV rays by absorbing 98% of its harmful rays. Without the ozone layer, we wouldn’t be able to live on Earth. Although the hole has been repaired by the choices of some governments, air pollution is still harmful to us. Air pollution can cause skin, heart, respiratory problems, and eye irritations. -Patrisia Manvelyan
