Agriculture is responsible for about 10 per cent of Canada's greenhouse gas emissions. These gases come from cows, but also from manure and from soils that have received manure or fertilizer. The challenge for scientists is to find ways to help farmers reduce these emissions.
What we find, in general, is that the more efficient the farming operations are, the less emissions we have. For example, methane that is produced by cows is a loss of energy for these animals. If we could convert this energy into meat or milk instead of methane, that would be a gain in productivity for the farmer.
The results of our research go also well beyond the barnyard; it can result in healthier woodlands and all sorts of ecosystems around the planet.
