Dr John's Blog

We all have our heroes – people we admire for what they have achieved, how they behave, or simply who they are.

Some of mine are:

  • George Monbiot, author and Guardian columnist
  • Atul Gawande, surgeon, researcher, writer
  • Douglas Tallamy, biologist and author of Bringing Nature Home
  • Carol Pasternak, the Monarch crusader
  • Elizabeth May, Leader of the Green Party of Canada
