Engineering Humans: A New Solution to Climate Change?
So far, conventional solutions to global warming — new government policies and changes in individual behavior — haven’t delivered. And more radical options, such as pumping sulfur into the atmosphere to counteract warming, pose a great deal of risk. There may be another route to avoid the potentially disastrous effects of climate change: We can deliberately alter ourselves, three researchers suggest. Human engineering, as they call it, poses less danger than altering our planet through geoengineering, and it could augment changes to personal behavior or policies to mitigate climate change, they write in an article to be published in the journal Ethics, Policy and the Environment.
