From the latest expert report on the evils of meat, to drugs that will make mean unpalatable, the government has the answers. Very small people. Eyes that don't rely on light. Pills to make you peaceful and empathic reducing or even eliminating conflict. No doubt about it, engineered humanity will be more healthful for the planet. We're still fighting global warming here. You can have one normal child, two medium sized ones or for a large family three midgets. How Engineering the Human Body Could Combat Climate Change - Ross Andersen - Technology - The Atlantic Some of the proposed modifications are simple and noninvasive. For instance, many people wish to give up meat for ecological reasons, but lack the willpower to do so on their own. The paper suggests that such individuals could take a pill that would trigger mild nausea upon the ingestion of meat, which would then lead to a lasting aversion to meat-eating. Other techniques are bound to be more controversial. For instance, the paper suggests that parents could make use of genetic engineering or hormone therapy in order to birth smaller, less resource-intensive children. Liao: That's right. It's been suggested that, given the seriousness of climate change, we ought to adopt something like China's one child policy. There was a group of doctors in Britain who recently advocated a two-child maximum. But at the end of the day those are crude prescriptions---what we really care about is some kind of fixed allocation of greenhouse gas emissions per family. If that's the case, given certain fixed allocations of greenhouse gas emissions, human engineering could give families the choice between two medium sized children, or three small sized children. From our perspective that would be more liberty enhancing than a policy that says "you can only have one or two children." A family might want a really good basketball player, and so they could use human engineering to have one really large child.
