The environmental problems faced by South Asia include the following:
- Lack of agricultural land
- Water pollution due to sewage entering rivers
- Air pollution caused by exhaust from vehicles and industry
- Flooding caused by heavy monsoons
- Climate change threatening the region
The options "Overabundance of fresh drinking water" and "Extreme cold weather year-round" do not accurately represent environmental problems in South Asia. South Asia generally struggles with water scarcity issues rather than an abundance, and extreme cold weather is not a predominant issue in the region.
