There are several things, including that we are looking at how we treat the soil, because the soils can be a sink for carbon, as I think you heard on Tuesday. We can actually reduce some of the CO2 in the atmosphere through the sinks.
Also, as I mentioned, the way we apply nutrients to the soil is very important, because nitrous oxide is a molecule that's released when you have too many nutrients in the soil. It's released through microbiome breakdown of different molecules. One molecule of nitrous oxide is equivalent to 298 molecules of CO2, so it's a big deal. If we can look at changing the microbiome and changing the way we apply fertilizers, we can reduce that heavily.
Methane is another one, which is from dairy cattle and mainly beef cattle. The digestive process gives off gases. It's significant. We can reduce that. We're working on science to reduce that. You can do it through genetics, through breeding. There are cows that are naturally more efficient with food. You can also do it through diet. We've been successful in developing lines of beef cattle and diets for dairy cattle through which we're actually reducing the GHG emissions of an animal per litre of milk or per pound of beef depending on the animal.
Those are two or three examples specifically in areas that we're working on now.
