Yes, chlorine can come from natural sources such as volcanoes, but they are not the primary source. But the rise of chlorine in the atmosphere is the refrigerants that have been released. Can chlorine in the stratosphere be from natural sources, such as volcanoes? False. Ozone in the Stratosphere absorbs and reflects harmful UV rays from the sun, not ground level ozone. Ground level ozone is actually harmful for humans when inhaled. Ground level ozone is what absorbs and reflects harmful UV rays from the sun. True or false?

This increases risk of skin cancer and cataracts in humans. In which of the following ways does ozone depletion affect humans? Yes, air samples taken from the stratosphere confirm that refrigerants such as CFCs and HCFCs make it to the stratosphere, where they destroy ozone.
