Greenhouse gas fear over increased levels of meat eating (BBC) [View all]

Global consumption of meat needs to fall - to ensure future demand for food can be met and to help protect the environment - a study says.

Research from Cambridge and Aberdeen universities estimates greenhouse gases from food production will go up 80% if meat and dairy consumption continues to rise at its current rate.

That will make it harder to meet global targets on limiting emissions.

"The average efficiency of livestock converting plant feed to meat is less than 3%, and as we eat more meat, more arable cultivation is turned over to producing feedstock for animals that provide meat for humans.

"The losses at each stage are large, and as humans globally eat more and more meat, conversion from plants to food becomes less and less efficient, driving agricultural expansion and releasing more greenhouse gases. Agricultural practices are not necessarily at fault here - but our choice of food is."
