Public health for the hunter-gatherer in us all.

In evolutionary terms, the transformations which humans have engendered in social, ecological and built environments are increasingly out of step with their biological makeup. We briefly review the evidence on health-relevant practices and status of our Paleolithic ancestors and contrast these with current food, transportation, work and governance systems with their associated impacts on human health. As public health and planning practitioners engaged in the EcoHealth Ontario Collaborative, we argue for recognition of our hunter-gatherer nature to promote joint efforts in building sustainable and equitable community infrastructures, both built and green. Although such efforts are underway at multiple jurisdictional levels across Canada, the pace is frustratingly slow for the burden of endemic chronic diseases and global environmental change which humans face. Reminding reluctant stakeholders of the hunter-gatherers in us all could bring about deeper reflection on the urgent work in redirecting community planning.
