David Waltner-Toews is a epidemiologist and veterinarian with an expansive vision: He addresses "zoonoses" -- diseases that are shared by animals and people. This inter-disciplinary project also looks at ecological systems and interactions among the creatures that live together in them. Some organizations practicing “one health" focus as much on the environment as on the health of animals and people. There are grounds for expecting further spread of zoonotic diseases because habitats are being disrupted by development and people can easily travel great distances before they know they are sick.
