Madam Speaker, it is fair to say that nobody would question that photosynthesis is a process and that things like trees and plants can actually act as carbon sinks, but I would suggest the member read some of the science on climate change, certainly on the issue of CO2. It is a pollutant, it is causing global warming, and the vast majority of the scientific community agrees with that.
