There are some environmental challenges ahead of us. We have an intensive system of agriculture that has put pressure on some of the soils and some of the water, and we're working through with farmers in a collaborative way to make sure that they continue to make profits but we continue to make progress, because without a story of integrity around land use, around environmental management and animal welfare, we will not be able to attract and expect to retain the premiums that we need out in the international market.
