Mrs. Schug's grade 7 and 8 class is participating in The Energy Diet challenge, sponsored by Canadian Geographic magazine. There are 10 challenges and we have until the spring to complete at least three of the challenges to be eligible to win prizes. There are $40,000 worth of prizes for the challenge. As a first step, we were asked to challenge someone in our family to use a reusable water bottle for a week and see how many plastic water bottles they save. 

Virtual Water
We have also been learning about Virtual water. Virtual water is water that is used to grow, make, package, process or transport a product. To quote the article we read from Canadian Geographic, 

Virtual water is “every drop consumed or polluted during growing, raising or manu¬≠facturing — be it a beef cow, a head of lettuce, a scoop of wheat or the fuel that powers transport vehicles.” 


We learned that: 1. It takes 2000 L of water to make all of the parts of a cheeseburger. 2. Producing vegetables requires less water than producing meat.  3. Of all meats, beef has the largest water footprint, or needs the most water. 

Here are some posters that students made showing how much water is used to make chocolate and how much water it takes to make a cheeseburger. 

How can you choose products that use less water? 1. Choose one day a week to not eat any meat - this is perfect for Fridays in Lent! 2. Try to buy local foods, such as at your local Farmer’s Market.  3. Skip having a treat sometimes and know that you’re helping conserve water.
