Could flexitarianism save the planet?

Scientists say a drastic cut in meat consumption is needed, but this requires political will

It has been known for a while that the amount of animal products being eaten is bad for both the welfare of animals and the environment. People cannot consume 12.9bn eggs in the UK each year without breaking a few.
