It is remarkable that nearly every scientist in genetics research is also engaged in the commerce of biotechnology. There are no detached observers. Everybody has a stake.

As Tizard points out, we’re constantly moving genes around the world, usually in the form of entire genomes. This is how chestnut blight arrived in North America in the first place; it was carried in on Asian chestnut trees, imported from Japan. If we can correct for our earlier tragic mistake by shifting just one more gene around, don’t we owe it

A third, nascent policy area would attempt to reverse climate change—for example, by putting particles in the atmosphere that would block out some of the sun’s rays. Such actions (termed geo-engineering) are controversial because their effects cannot be confidently predicted. The science is still in its early days. There is no process for approving
