You're right, it is a well-adopted tool. I think more research is going into how we can further increase carbon sequestration with tools such as grazing animals. Admittedly, I think there's quite a bit more research to be done there. I think the research has shown us there is quite a bit more potential there.
Bob talked about our having a greenhouse gas footprint that is 50% of the world average, but that doesn't even take into consideration the carbon sequestration that happens in the beef industry.
