Our ozone layer serves as a lifesaving UV barrier for planet earth, functioning to absorb most of the sun’s ultraviolet radiation. At the same time, ground-level ozone pollution is extremely harmful to human health. As the complexity of ozone pollution is often misunderstood, let's take a closer look at this particular pollutant.
