The sun receives a constant stream of energy produced by nuclear processes that generate an immense amount of heat, light, and radiation. This radiation hits the atmosphere and is absorbed by the ozone layer which reduces the most harmful. At the center of our solar system is a star that we call “The Sun”. Deforestation.

We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. 5] Additionally, the reaction of these volatile chemicals contributes to ground-level ozone production, which, unlike ozone in the stratosphere, is hazardous to human health.
