In order to support a growing world population with food and water, we need to use farmland far more effectively than today. Of all the surface area used for food production, 80 per cent is for the production of meat and dairy products, ie animal breeding and animal feed. Only 20 percent are used for herbal food for humans.
To produce meat requires at least ten times as much land as growing vegetables with the corresponding nutrition and energy content. It is also extremely water-intensive, compared with the production of vegetables. Consumption of meat and dairy products therefore needs to be reduced sharply and replaced by more vegetable food. In order to get the necessary proteins and amino acids, protein crops are excellente sources, such as beans, lentils, chickpeas, soya and oats.
