I think it's important to understand that every breath we take is 78% inert nitrogen—every breath you take, every move you make, it should be a song. The Haber-Bosch process turns that inert nitrogen into fertilizer that ultimately supports 50% of the protein in every man, woman and child on planet earth. It's also a question of how you sustain life on Mars, where it's only 2.6% inert nitrogen.
From a standpoint of what we could do in agriculture, I already talked about some of the things. The ability for us to utilize nitrogen inhibitors to reduce the conversion of fertilizer into urea or into nitrous oxide is important. The ability for us to include methane reduction agents into feeding, when you're feeding cattle.... There are methane reduction agents being researched right now that can reduce the methane or the burps from cattle by 50% to 75%. Seaweed extracts are one of these. Again, if you incent farmers to do these things, they'll find ways to do these things.
I think the most important thing we can do is grow more crop. It takes 3.3 pounds of nitrogen to grow a bushel of canola, and 1.5 pounds of nitrogen to grow a bushel of corn. The more corn you grow, paradoxically, the more root mass you have and the more carbon sequestration you have.
The idea of reducing nitrous oxide emissions from agriculture is laudable, but all the discussion.... If we do this and achieve a 0.0028% reduction in Canada, this is not what we should be going after. We should be going after other things that make our farmers more productive, not looking at policies that are punitive to agriculture production in Canada.
