NOVA SCOTIA, October 2010: If demand for meat, poultry, eggs and dairy keeps pace with projections, by 2050 the environmental consequences of livestock production could be responsible for 70 percent of the total greenhouse gas emissions considered a safe threshold for the planet, new research says.
By comparison, a UN report estimated that livestock production in 2000 produced about 14 percent of global greenhouse gas emissions. This leaves little room for all of the other sources of greenhouse gases, such as transportation and electricity, which now account for more than 80 percent of emissions.
