PostSubject: How Engineering the Human Body Could Combat Climate Change Mon Mar 12, 2012 9:32 pm

Is climate change simply a modern, secular metaphor for human suffering (politicians/scientists promising a utopia in which there are no differences/discrimination either in temperature or racial nature)?

Quote :
Is Bioengineering More Efficient Humans the Solution to Climate Change?

A new paper, published in Ethics, Policy, and the Environment by NYU bioethics professor S. Matthew Liao, poses an answer: engineer humans to use less. The general plan laid out by Liao is straightforward, ranging from using pharmacological behavior modification to create an aversion to meat in people, to using gene therapy to create smaller, less resource-intensive children. The philosophical and ethical questions, on the other hand, are absurdly complicated.



Your paper also discusses the use of human engineering to make humans smaller. Why would this be a powerful technique in the fight against climate change?

Liao: Well one of the things that we noticed is that human ecological footprints are partly correlated with size. Each kilogram of body mass requires a certain amount of food and nutrients and so, other things being equal, the larger person is the more food and energy they are going to soak up over the course of a lifetime. There are also other, less obvious ways in which larger people consume more energy than smaller people—-for example a car uses more fuel per mile to carry a heavier person, more fabric is needed to clothe larger people, and heavier people wear out shoes, carpets and furniture at a quicker rate than lighter people, and so on.

And so size reduction could be one way to reduce a person’s ecological footprint. For instance if you reduce the average U.S. height by just 15cm, you could reduce body mass by 21% for men and 25% for women, with a corresponding reduction in metabolic rates by some 15% to 18%, because less tissue means lower energy and nutrient needs.

What are the various ways humans could be engineered to be smaller?

Liao: There are a couple of ways, actually. You might try to do it through a technique called preimplantation genetic diagnosis, which is already used in IVF settings in fertility clinics today. In this scenario you'd be looking to select which embryos to implant based on height.

Another way to affect height is to use a hormone treatment to trigger the closing of the epiphyseal plate earlier than normal---this sometimes happens by accident in vitamin overdose cases. In fact hormone treatments are already used for height reduction in overly tall children. A final way you could do this is by way of gene imprinting, by influencing the competition between maternal and paternal genes, where there is a height disparity between the mother and father. You could have drugs that reduce or increase the expression of paternal or maternal genes in order to affect birth height.

Pathetic.
