He expects the ZERI network to contribute to a fundamental solution so that Kamakura can become the first waste-free city in Japan. In line with the ZERI concept, this means that value would be added to all waste to produce useful products. Responding to the needs of all on Earth in terms of water, food, housing, health care, energy and jobs. The ZERI Foundation's goal is the efficient production of all the goods and services that society needs without any form of waste - no liquid waste, no gaseous waste, and no solid waste. Once mercury enters the environment, microorganisms in lakes and rivers convert it to the more toxic methylmercury, where it builds up in fish and wildlife.
Mercury can cause neurological damage.
Most human exposure to mercury comes through eating fish. Pregnant women, women of childbearing age, and young children are particularly at risk from mercury exposure. In fact, the National Academy of Sciences noted in a recent report that more than 60,000 children annually may be at risk for learning disabilities because of mercury-contaminated fish eaten by their mothers during pregnancy. Over 90 percent of the Minnesota lakes and rivers that have been tested receive fish consumption advisories due to mercury contamination, totaling over 800 in 2000. Each fever thermometer contains approximately one gram of mercury, which may not seem like much.
