Why is ozone depletion considered not only a chemical problem but also a biospheric problem?
Answer and explanation
Correct answer: Because increased ultraviolet radiation can affect organisms and ecosystems
The governing concept is the protective role of stratospheric ozone. When ozone concentration decreases, more harmful ultraviolet-B radiation can reach Earth’s surface. This may damage plant tissues, aquatic plankton, animal health and human skin and eyes, so the effect extends through the biosphere. Option A correctly states this chain; the other choices describe impossible consequences.
