The correct answer is Water pollution

Key Points

  • Water pollution is the type of pollution that leads to cultural (accelerated) eutrophication.
  • Cultural eutrophication is the process where water bodies receive excess nutrients, such as nitrates and phosphates, due to human activities like agriculture and industrial discharge.
  • This excess nutrient load leads to rapid growth of algae and aquatic plants, which can deplete oxygen in the water, harming aquatic life.
  • It is a significant environmental issue affecting lakes, rivers, and coastal waters, leading to degraded water quality and loss of biodiversity.

Additional Information

  • Eutrophication can be natural but is often accelerated by human activities (cultural eutrophication).
  • Key sources of nutrient pollution include agricultural runoff, wastewater discharge, and industrial effluents.
  • Preventative measures include improving agricultural practices, enhancing wastewater treatment, and implementing policies to control industrial emissions.
  • Restoring affected water bodies often involves reducing nutrient inputs and managing the growth of algae and aquatic plants.
