Appropriate Technology for Protected Areas

Thank you for allowing me to join the conversation. Appropriate technology is the only way to the future. We have lived in an ecohouse in the city for 25 years that uses a composting, water-free toilet. We have saved 5,000,000 L of drinking water so far. It is a paradox that in the 21 century , in an educated world, city dwellers still use drinking water for flushing toilets. It must be & will be banned. it is a beautiful form of appropriate technology, saving 200,000 L/yr & producing lots of good soil so we do not need to rely on artificial fertilizers!!!
