Yining Chen here. Every month, my family used 8 tons of water—enough to fill 15 pools—and 200 degrees of electricity. After four years of small changes, we cut those numbers in half and saved a mountain of fuel. Today I want to show you the simple switches that let kids like us rescue the planet one drop and one watt at a time. My name is Chen Yining, and my English name is Christine. I'm 10 years old.I love reading and am very good at playing the guzheng. I have a deep love for Chinese culture and hope I can tell Chinese stories in English.
