Demand for meat makes land a net source of green-house gases

the conversation: "We wanted to know how human activities on the land are affecting these sinks and sources. Globally, the land currently absorbs more CO₂ than it produces (we don’t include fossil fuels in this), so it is considered a carbon sink. But we found that this is overwhelmed by production of methane and nitrous oxide, so overall the land is a source of greenhouse gases."
