Multiple choice general knowledge science & technology

It is known that if Ozone layer is depleted, ultraviolet rays, especially UV-B reaches the ground. Which one of the following is NOT an impact of Ozone depletion?

  1. Human health is severely impacted with impacts such as Skin Cancer, cataracts and damage to immune systems

  2. Phytoplankton production is reduced leading to severe impact on marine ecosystems

  3. Ozone depletion directly leads to natural calamities such as storms, floods etc

  4. By severely damaging plants and other sinks of greenhouse gases, ozone depletion leads to climate change

C Correct answer
Explanation

Ozone depletion increases UV-B reaching earth, causing skin cancer, cataracts, immune damage (A), reduces phytoplankton (B), and damages plants worsening climate change (D). However, it does NOT directly cause storms/floods - those are separate climate phenomena. This tests understanding of ozone depletion's actual impacts versus speculative effects.
