35 per cent of the world's people can be fed on a meat-based diet. A plant diet could feed everyone - then plus some.
Sir Crispin Tickell
It takes about 10kg of good quality plant protein - such as wheat and soya - to produce 1kg of meat protein.
The amount of veg protein fed to the US beef herd would feed almost the entire populations of India and China -
two billion people.
Veg consumption is much more efficient than growing feed for meat production and dairying.
90 per cent of the UK's animal feed protein concentrates come from poor countries - often those where children die from starvation.
Amount of grain needed to end extreme hunger - 40 million tonnes. Amount of grain fed to animals in the West - 540 million tonnes.
