Study Notes
Pollution and Health
- Up to 40% of premature deaths worldwide are caused by pollutants in water, air, and soil.
- Majority of these deaths occur in developing countries.
Water Pollution
- 1.1 billion people globally have little or no access to clean water.
- In many developing regions, the same water is used for drinking, cooking, washing, dumping sewage, and hazardous waste.
- 80% of infectious diseases worldwide are caused by contaminated water.
Soil Pollution
- Pollutants like metals and pesticides contaminate the food supply through soil pollution.
- Soil pollution causes major health risks to entire ecosystems and reduces land suitable for agricultural production, contributing to global food shortages.
- Industrial and domestic waste dumping, as well as natural disasters, contribute to soil pollution.
Developed vs. Developing Countries
- Wealthy countries, like the US, have protection agencies that monitor the food supply and warn the public before major disease outbreaks.
- Developing countries lack these luxuries, leaving farmers to grow food in contaminated soil to survive and avoid starvation.
