The Environment Agency have issued a warning that the UK could soon be hit by a massive water shortage. In their report, they predict that demand for water could increase by 25% by 2020. Scientists are concerned that we will not have enough water to grow enough food to feed a growing population. Food security is a major issue worldwide and a severe water shortage will significantly hinder any plans to produce more food.

A typical balanced diet requires around 3,500 litres of water per day. The lower down on the food chain you eat, the less water your diet requires. Cereals and grains require around 1,000 litres per kilogramme, compared to 15,000 litres for the same amount of beef or 6,000 litres for the same amount of poultry. One glass of milk requires 200 litres of water.

Growing demand for food and water, caused by a growing population, mean that we have to consume as efficiently as possible, making choices that use the least amount of resources. Diets high in meat and dairy are not sustainable and this irresponsible dietary choice massively hinders our chances of eradicating world hunger.
