Important foods that are actually causing water shortages

When you are ordering from a restaurant or perusing the aisles at the supermarket, it is often not obvious the environmental impact that certain food products cause.

One of the growing pressures on Earth is the lack of fresh water, according to the Worldwide Wildlife Fund (WWF) some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. Inadequate sanitation is also a problem for 2.4 billion people exposing them to diseases such as cholera and typhoid.

Many of the water systems that help ecosystems and feed the growing human population have become stressed. On top of this climate change is altering patterns of weather and water around the world, causing shortages and droughts.

By 2025, two-thirds of the world's population may face water shortages. And ecosystems around the world will suffer even more.

Agriculture consumes more water than any other source and wastes much of that through inefficiencies.
