Ozone depletion threatens which life forms?

• A. Wild and marine life
• B. Domestic pets
• C. Only humans
• D. Only trees

Answer: (A)

Raising UV radiation reaching the surface is what ozone depletion does, and that hurts living systems across the globe. The ozone layer normally shields us from most of the sun’s harmful UV-B rays; when it’s thinning, more UV-B gets through. That increased exposure can damage DNA, raise cancer risk, impair vision, and suppress immune function in many organisms. In the ocean, higher UV can reduce phytoplankton photosynthesis, disrupting marine food webs; on land, various wildlife species exposed to more UV suffer similar stress. Because this pressure affects a broad range of life across ecosystems, the option that refers to wild and marine life best captures the widespread impact of ozone depletion.
