The Populations Problem by Herman Daly on October 21, 2012:

"The usual counter to such thoughts is that we can improve the efficiency by which resource throughput maintains dissipative structures. For example, a car that lasts longer and gets better mileage is still a dissipative structure, but with a more efficient metabolism that allows it to live on a lower rate of throughput. Likewise, human organisms might be genetically redesigned to require less food, air, and water. Indeed smaller people would be the simplest way of increasing metabolic efficiency (measured as the number of people maintained by a given resource throughput). To my knowledge, no one has yet suggested breeding smaller people as a way to avoid limiting the number of births and neither do I. We have, however, been busy breeding and genetically engineering larger and faster-growing plants and livestock, as well as building larger exosomatic organs, so that we become smaller relative to the other organisms we depend on, although we remain the same size absolutely. So far in the empty world, the latter dissipative structures have been complementary with populations of human bodies, but in our finite and full world, the relationship has become competitive.
