Threats to Biodiversity · NCERT Biology

The 'Lungs of the Planet' is a title given to:

  1. By increasing salinity and osmotic stress across the open ocean surface
  2. By causing sea-level rise that submerges coastal habitats
  3. By reducing the CO2 available for photosynthesis in aquatic plants
  4. By promoting stratospheric ozone thickening over polar coastal zones
Show answer and explanation

Correct answer: By causing sea-level rise that submerges coastal habitats

Global warming leads to the melting of polar ice caps and thermal expansion of seawater. The resulting sea-level rise can submerge mangroves, salt marshes, and low-lying coastal breeding grounds.
