How Science Can Solve the Crisis
Water Purification:
- Filtration removes solid particles
- Chlorination kills bacteria
- UV purification destroys microorganisms
- Reverse osmosis removes salts and harmful substances (World Health Organization; Centers for Disease Control and Prevention)
Sustainable Solutions:
- Solar water disinfection
- Rainwater harvesting
- Wastewater recycling
These methods are especially effective in regions where natural resources like sunlight can be used for purification.
