Genetic engineering may be the most environmentally beneficial technology to have emerged in decades, or possibly centuries, says Jonathan Rauch of the Brookings Institution.
For instance, take no-till farming. Most of the fertiliser runoff that causes fish-killing algae blooms comes from farmland. By all but eliminating agricultural erosion and runoff, continuous no-till farming could revolutionise water quality in areas like the Chesapeake Bay watershed. No-till farming is most compatible with genetically modified foods, which require much less fertiliser. One-third of the U.S. soybean crop is already grown this way.
Other examples include:
Bio-engineers are also working on crops that tolerate aluminium, which is a major soil contaminant in the tropics. Returning an acre of farmland to productivity, or doubling yields on an acre under production, reduces the amount of virgin forest or savannah that will be stripped and cultivated. Thus we may be able to feed the world, including the expected increase in population, by cultivating fewer acres, and that may be the most important benefit of all, says Rauch.
