Why does depletion of the ozone layer increase danger to the biosphere?
Answer and explanation
Correct answer: Because more ultraviolet radiation can reach Earth's surface
Stratospheric ozone absorbs much of the Sun’s biologically harmful ultraviolet radiation, especially UV-B. When the ozone layer is depleted, a greater amount of ultraviolet radiation can reach Earth’s surface. Excess UV can damage skin and eyes, harm plants and aquatic organisms, and disturb ecosystems, thereby threatening the biosphere. Option C states the direct mechanism; A, B and D are unrelated or impossible.
