John Todd (Canadian Biologist)
John Todd (born 1939) is a Canadian biologist working in the general field of ecological design. He addresses problems of food production and wastewater processing by using ecosystems technologies that incorporate plants, animals and bacteria. Todd has developed "Arks" or "bioshelters", ecologically closed "life-support systems" with the goal of sustainable functioning. He combines alternative technologies for renewable energy, organic farming, aquaculture, hydroponics and architecture to create "living machines" or "eco-machines". John Todd is a co-founder with Nancy Jack Todd of the non-profits New Alchemy Institute (1969–1991) and Ocean Arks International (1981), and the founder and president of the design and engineering firm John Todd Ecological Design Inc. (1989). A research professor emeritus and distinguished lecturer at the University of Vermont, Todd has published books on ecological design, as well as over 200 scientific papers, popular articles and essays.

Hamilton is a port city in the Canadian province of Ontario.
