Learn how climate change is affecting the water supply in this video from Power of Us. Climate change is affecting weather patterns, making some areas dryer. In California, teenager Shreya Ramachandran noticed the harmful effects of droughts, so she designed a system for households to reuse grey water. Grey water is water that has been used gently for cleaning and can be reused for other purposes. Instead of regular soap, Shreya used soap nuts, a plant that is often used to clean clothes in India. Support materials include an introduction to grey water from Shreya’s organization The Grey Water Project, a water filtration activity, and discussion questions.
