Concept:Environmental pollution arises from multiple human-induced factors. The main causes are population growth, modernization, and social customs, each contributing to the degradation of air, water, land, and soil.
Explanation:- Population: Rapid increase in population leads to overpopulation. This causes overfarming, deforestation, water pollution, eutrophication, and global warming — all harmful to the environment.
- Modernization: Transition from traditional to industrial, urban society results in depletion of natural resources, water and land pollution, and release of chemicals that damage soil productivity.
- Social customs: Certain community practices can negatively affect the environment if not carefully managed. They may harm air, water, plants, animals, and natural resources.
- All three factors — population, modernization, and social customs — are significant contributors to environmental pollution.
