There is such a thing as a water footprint. In the same way there is a carbon footprint, water footprint of an object seems tough to wrap your head around. But let's think about it. How much water does it take to make burgers?

Burgers for example, require meat, and well, water and lots of it. The USGS estimates it takes up to 4,000 to 18,000 gallons of water to produce A JUICY BURGER. And it depends on the conditions the cows are raised in to. While the water doesn't directly go into your burger, it's used to feed, hydrate and service cows.

The video below is a visualization of how much of water that goes in to a burger. It's also part of the European Commission campaign to raise awareness about resource efficiency, according to PSFK. The Generation Awake campaign features a site dedicated to teaching Europeans about water efficiency and they guarantee to shock you after you see the statistics about the water footprints of various products.

One good example: hosing your lawn for nine hours is the same amount of water it takes to make a pair of jeans.

There are many ways to go about reducing your water footprint. The first is to buy more secondhand goods, and the next is to waste less food - which means order less if you know you can't finish or eat so much. Also, eat less meat.

Generation Awake is launching a video challenge asking participants to visually demonstrate the amount of water needed to make chocolate, coffee, hamburgers, beer and shoes.
