More research

Here is a nice poster I found that lets you know how much water is used to produce certain types of products. It's very well done and very informative, I would never have taught it would take 1170 litters if water for one breast fillet of chicken (300g) or 2500 litters for one big piece of cheese (500g). It just shows how much water is needed for everyday life.
