I fully agree with the point she made. It's absolutely critical that we maintain and ensure that we are doing sustainable harvesting, and not removing excessive amounts from and detrimentally impacting the soil. There are a number of studies that have been done that show there is a portion of the biomass that can be removed sustainably. That's where we have to put our focus.
Even once you have the science in place, it's really important that we have the traceability and the ability to track where we're moving the biomass from, so that we can continue to ensure that we're doing it sustainably and appropriately.
When I made my point about 50 million tonnes of agricultural biomass available, that is not the total amount of agricultural biomass that is available. That is based on a significantly reduced factor of the total biomass generated.
I would say that there are only a few crops where we generate sufficient biomass that there's an opportunity to remove it. In the case of us here in Ontario, it's really around wheat straw and corn stover, in particular, where you get excessive amounts of biomass that you can sufficiently remove without having long-term, detrimental effects on the soil.
