Q.Ozone depletion will cause

Step 1. Depletion of the ozone layer allows more UV radiation to reach earth's surface, causing skin cancer, decreased human immunity, plant-protein mutation, and damage to phytoplankton and fish productivity.

Step 2. Among the given options, forest fires (a), eutrophication (b) and biomagnification (c) are effects tied to other pollution pathways covered elsewhere in the unit (fire ecology, excess nutrients in water, and persistent pesticide accumulation respectively), not to ozone depletio …

Eliminate the options that belong to unrelated pollution pathways (eutrophication = water nutrient overload; biomagnification = pesticide accumulation up a food chain; forest fire …

• Assuming ozone depletion and global warming are unrelated because they involve different gases (CFCs vs CO₂/CH₄) -- both are atmospheric-layer disrupti …
