Cactus flesh cleans up toxic water

The video explores the innovative use of cactus mucilage for environmental cleanup, particularly in water purification and oil spill management. Norma Alcantar, inspired by her grandmother's traditional methods in Mexico, conducts research supported by the National Science Foundation. Her lab tests reveal the effectiveness of cactus mucilage in removing pollutants, offering a sustainable and cost-effective alternative to chemical dispersants. Field tests in Haiti post-earthquake confirm its potential for rapid water decontamination. The video suggests future applications in local harvesting of cacti for disaster response, highlighting the shift towards natural solutions.
