An Earth's atmospheric ozone graph is provided: Graph shows altitude in kilometers from zero to 35 on the left vertical axis and miles from zero to 20 on the right vertical axis. The horizontal axis shows ozone concentration from low to high. In less than five kilometers (about 3 miles), local ozone as air pollution ('bad ozone') exists in low concentrations. Up to 15 kilometers (about 10 miles) is the tropospheric ozone (air pollutant). From 15 kilometers to about 22 kilometers (about 15 miles), ozone concentration increases, and then decreases from there. This is the ozone layer. Essential ozone for UV protection ('good ozone'). Stratospheric ozone reflects UV. © OurWorldinData 2023, CC BY-SA 4.0 Based on the information provided, what is true? Ozone in the troposphere may decrease the chances for lung diseases. Ozone in the stratosphere may increase the number of asthma cases. Ozone in the stratosphere may reduce the chances of skin cancers. Ozone in the troposphere may intensify the effects of high radiation.
