Harmless Gas To Kill Us All Unless We Go Veggie
The study by 200 European experts says reactive nitrogen contributes to air pollution, fuels climate change and is estimated to shorten the life of the average resident by six months.
Nitrogen is the most common element in the atmosphere and is harmless...people in many areas still suffer from nitrogen-related air pollution, including small particulates that get sucked deep into the lungs, and ground-level ozone - a strongly irritant gas formed by the action of sunlight on reactive nitrogen.
Lead editor, Mark Sutton from the Centre for Ecology and Hydrology near Edinburgh, told BBC News that 80% of the nitrogen in crops feeds livestock, not people.
"It's much more efficient to obtain protein by eating plants rather than animals," he said.
"If we want to help the problem we can all do something by eating less meat. Eating meat is the dominant driver of the nitrogen cycle in Europe."
