Cleaner pig poop could reduce bacon's environmental burden
Genetically modified pigs produce fewer dangerous pollutants.

Pigs can't naturally digest nitrogen, a dangerous climate pollutant.
Scientists have been tinkering with the genes of plants and animals for years to cure diseases, make fruits and vegetables heartier or tastier, produce crops that are resistant to pests, drought, and other scourges, or prompt fish to grow faster.
In recent years, however, thanks in part to the ravages of climate change, some researchers who manipulate genes have assumed a new focus: saving the planet. Among other things, they are making grass more palatable for cows and designing climate-friendly cattle that expel less heat-trapping methane. And now they have turned to pigs.
