Eat less meat to save the planet, says study

Scientists believe eating beef is particularly damaging to the environment

1 September 2014

Scientists are warning that we all need to eat less meat to help protect the environment. The study, by Aberdeen and Cambridge Universities, says that greenhouse gases from food production will rise by 80% by 2050 if we don't change our eating habits.

The study examines what needs to be done if greenhouse gas emissions¹ from farming are to be cut alongside emissions from transport, homes and industry.

It says, on current trends, with people round the world getting richer and eating American-style diets, farm emissions will boom as forest land is converted to agriculture and fertiliser is sprayed on the fields.

The report says the emissions' growth can be contained somewhat, if farmers in developing countries are helped to improve their yields from existing fields. It'll help to stop wasting food too, the authors say.

But then there's the really hard bit: they say persuading people to eat less meat and dairy produce can actually lead to a big overall cut in emissions from farming.
