प्रश्न
A lot of fish are dying near a sea shore. Describe any two possible causes.
उत्तर
- Oil spills: Accidental oil spills in the sea can taint water and destroy marine life. Oil can cover fish's gills, making breathing harder and disturbing their usual behaviours.
- Industrial waste: Discharge of industrial contaminants into water can cause pollution and harm aquatic life, particularly fish. Chemicals and poisons from industrial operations can pollute water and harm fish health.
