I thank the witnesses for coming in. I have some brief questions. From listening to previous speakers, if there were 100 million cattle in the world in 1930 and if there are also 100 million cattle in the world today, have the same number of cattle today contributed more than they did in 1930? Will the witnesses explain that? Is there more methane in the air or are the cattle different?
