Food shortages could force people to adopt a vegetarian diet within the next 40 years. Moreover, the consumption of meat in the United States is expected to decline as it’s already down 12 percent since 2007.
“More than one-fourth of all the water we use worldwide is taken to grow over one billion tons of food that nobody eats. That water, together with the billions of dollars spent to grow, ship, package and purchasing, is sent down the drain,” stated Torgny Holmgren, Executive Director of the Stockholm International Water Institute (SIWI).
The shortages could be due to the growing awareness of the global consumption security issues. However, we still have a long way to go.
Stockholm International Water Institute (SIWI) leading water scientist stated that about 20 percent of protein in human diets is currently animal-based, but unless that drops to 5 percent by 2050, there won’t be enough food to nourish the additional 2 billion people estimated to be alive by 2050.
According to a SIWI release, the raising of meat and fish require a lot of water and one-third of it is either lost or wasted. If nothing is done, pressure on water resources will threaten security.
“Reducing the waste of food is the smartest and most direct route to relieve pressure on water and land resources. It’s an opportunity we cannot afford to overlook,” Holmgren said.
While they are not asking people to adopt the vegetarian diet, they recommend that we cut down on the amount of meat we consume, save water by reducing food waste, increase productivity, and recycle waste water.
