If we want eternal life, then we’ll need to rewrite our bug-ridden genetic code and become god-like. “May all that have life be delivered from suffer… - David Pearce

Many city-dwellers have a romanticized conception of the living world. From another perspective, some "conservation biologists" favour e.g. "". By contrast, I think any truly compassionate person should be horrified at the terrible suffering of Nature "red in tooth and claw". Why not aim for a cruelty-free world instead?

Here the question comes down to an analysis of risk-reward ratios - and our basic ethical values, themselves shaped by our evolutionary past. Lest extension of the new reproductive medicine seem too rashly experimental even to contemplate, it's worth recalling that each act of old-fashioned sexual reproduction is itself an untested genetic experiment, the outcome of random mutations and meiotic shuffling of the genetic deck, and with no happy ending to date. So just who are we to accuse of reckless gambling? As it stands, all of us are genetically predestined to grow old and die; and in the course of a lifetime, the great majority of humans will experience periods of intense psychological distress, for instance loneliness and heartache after an unhappy love affair. Our social primate biology ensures that most of us sometimes experience, to a greater or lesser degree, all manner of nasty states that were genetically adaptive in the ancestral environment e.g. jealousy, resentment, anger, and so forth. Hundreds of millions of people in the world today suffer bouts of depression; others live with chronic anxiety. One might say these phenotypes are part of what it means to be human. Worse, we pass a heritable predisposition to these horrible states on to our children.

[I]n the wake of the growth of the animal-rights movement, there has recently arisen a hitherto unfelt need to demonise and demean our non-human victims - and those who try to help them - now that our previously well-nigh unquestioned right to kill and exploit them is being challenged. Bloodsports enthusiasts, for instance, currently spend a lot of time cataloguing the alleged depredations of our victims on the environment. Recreational animal-killers go to extraordinarily lengths to avoid admitting that they themselves enjoy hunting and killing other creatures for fun. But then until a few years ago such rationalisations seemed scarcely called for. Selfish DNA had honed our intuitions so that the most agonising bloodshed seemed simply "natural".
