multiply 250 grams by 40 billion

Dr Mike Johnson: "If we can get birds to grow to a certain point in their production cycle and in doing so they use 250 grams less of feed per bird - now if you multiply 250 grams by 40 billion and convert that to tonnes of grain that you don't need any more you can then do another mathematical calculation that converts that to how many hectares of land you don't now have to use to produce that grain. So it becomes an issue of, as the world population increases and pig meat and poultry meat become the preferred meats because they are so efficient in converting grains into muscle mass, you don't have to then go out and destroy more arable land or produce more arable land to produce the grain to feed the animals. It becomes a way of saving environmental impact in the long run as well as reducing the chemical impact that's actually used in the birds itself."
