C. Ben Mitchell challenges those who propose to re-engineer the human species :
Here is the argument offered by Matthew Liao, Anders Sandberg, and Rebecca Roache. Climate change is the result of human corruption of the environmentso-called anthropogenic causes. Climate change affects food production, access to water, health, and the environment. Since, in their view, millions could suffer from the consequences of climate change something radical must be done. Recycling, tax-incentives, and large-scale manipulation of the environment are, according to the authors, either too negligible or too grand to be effective. Geoengineering, in particular, is disadvantageous because in many cases, we lack the necessary scientific knowledge to devise and implement geoengineering without significant risk to ourselves and to future generations (p. 4). So, in one breathtaking leap, the authors argue that we ought to consider biomedical modification of humans to make them better at mitigating climate change.
