Why is an excess of CO₂ in the atmosphere considered undesirable even though it is required by plants?

  • 1

Excess carbon dioxide intensifies the greenhouse effect, driving global warming, polar ice melt and ocean acidification that degrades marine life, outweighing any potential photosynthetic benefits to plants.

    1. Although plants utilize carbon dioxide for photosynthesis, excessive atmospheric concentrations intensify the greenhouse effect, causing unmanageable global warming. This thermal disruption triggers extreme weather, shifts monsoon rainfall and melts polar glaciers, causing coastal flooding. Furthermore, excess atmospheric carbon dissolves into oceans, producing ocean acidification that damages coral reefs and marine phytoplankton ecosystems.
