Trudeau Rooftop Garden"What Can One Person Do?" began as a TEDx talk created in response to the despairing question of a student at Dalhousie University in Halifax, Canada.

 "The problems are so huge," she said, "so various, so overwhelming. What can one person do?"

As a matter of fact, one person can do an amazing amount. This keynote presents stories and video clips of astonishing people from The Green Interview whose lives and careers constitute a stirring response to that question. 

In this talk, the audience meets,  among others

  • an Icelander who has single-handedly ended most commercial fishing for Atlantic salmon
  • an Englishman who builds hydrogen-powered cars and aims to reform the whole automobile industry
  • a Dutch woman who forced the Netherlands government to honour its climate-change commitments
  • a Canadian who has created the world’s first commercial organic rooftop farm
  • a Bengali educator who turns peasant grandmothers into solar engineers and entrepreneurs
  • a British scientist whose work on chimpanzees changed our understanding of human beings
  • an Irishman who abandoned the use of money – and now has 43,000 followers in 168 nations
  • an Ecuadorian who won a $9.5 billion lawsuit against Chevron for polluting the Amazon.

These bold, pioneering social adventurers are a tonic for the spirit and an antidote to despair -- and that's what this surprising and entertaining keynote is designed to provide.

What can one person do? One person can change the world.

And that one person can be you.
