What happens when theory and practice collide? The theory is that carbon taxes reduce emissions by penalizing people for emitting greenhouse gas. That is the theory.
Tomato farmer Bob Mitchell, owner of Ottawa-based SunTech Greenhouses, is more concerned with practice.
He releases CO2 into his greenhouse to encourage better production. The federal government charges carbon tax on that CO2 even though none goes into the atmosphere.
The tomato tree absorbs it, just like they taught us in grade school.
