Breathing is bad for the environment.
Breathing is contributing to global warming
A new study claims that the gases expelled from human lungs during respiration are contributing to global warming as the methane and nitrous oxide in the air exhaled makes up 0.1 per cent of the UK's greenhouse gas emissions.
Humans also contribute to environmental harm with the release of gases from burping and farting as well as emissions that come from the skin that go unnoticed.
Dr. Nicholas Cowan, an atmospheric physicist at the UK Centre for Ecology and Hydrology in Edinburgh, said: "Exhaled human breath can contain small, elevated concentrations of methane (CH4) and nitrous oxide (N20), both of which contribute to global warming.
"We would urge caution in the assumption that emissions from humans are negligible."
