Ozone occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays. On the other hand, tropospheric ozone artificialy occurs in the lower atmosphere, where it polluts the air and slowly warms the earth.
