If I could just add in, Duane, I think we're working on the finer details of the quantification. We do know there is about 1.5 billion tonnes of carbon within the grasslands that are managed by beef producers, but when we go to add even more carbon through best management practices, there's further research to be done there to get it to a little bit finer detail.
What we do know is that, when lands are converted, if it's converted into a cityscape or if it's converted into some other agricultural use, about 30% to 40% of the carbon is lost.
