In terms of both plants and animals, we literally need to be breeding for drought tolerance, for lower water needs. We can do that, if we're encouraged to do it. We also need to look at improving the practices we put in place to reduce water losses. We need to be looking, I think—and I'm probably not the one to speak to this—at regulations around irrigation and water capture in many of our different aquifers. It has always been free, and we don't give it the value that it has.
Again, we need to be looking at not just breeding our current plants and animals, but at all of the indigenous plants and animals that may have innately greater efficiency of growth in the absence of excess water so that we can, again, do the best with less.
The other question was with regard to waste streams. Every aspect matters. We need to harvest more efficiently so that we're not losing product in harvesting; we need to make sure that what we harvest is used as thoroughly as possible. Just as now we use canola seed for oil production and use the rest of the plant to feed animals canola meal, there are probably other plants and things that we ought to be using more fully, so that we're capturing all of their value, again without depleting the soil too much of roughage.
There are many examples around this kind of thing that we really ought to be doing. We need to be processing food in a very effective way and processing it so that it is nutritious but also so that it meets the taste needs of the consuming public.
We need processing, storage, and harvest. Those would be the three pieces that are the most obvious in terms of reducing waste.
