Last week, climate scientist Peter Kalmus shared with The Tyee his daily habits for low climate impact.

Kalmus is a vegetarian, grows his own food, keeps bees, reuses greywater and commutes by bike. But most importantly, he no longer travels by air.

In his line of work, air travel made up two-thirds of his annual emissions. He doesn't think most people know the high climate impact of flying. "There's no better way to warm the planet than to fly in a plane," Kalmus writes. "If you fly coach from Los Angeles to Paris and back, you've just emitted three tons of CO2 into the atmosphere, 10 times what an average Kenyan emits in an entire year."

Kalmus explains that it took three full years to quit flying. He admits his actions alone can't change global warming, but believes changing our habits can open up social and political space for large-scale change.

With all this in mind, we ask if Tyee readers are willing to lead by example.
