Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Using water at home
Water is a fundamental resource. Every day we use large amounts of water in our homes for washing, cooking, drinking and cleaning.
According to the website https://www.anglianwater.co.uk/_assets/ … t_home.pdf " in 1830 one person in the UK would have managed with 18 litres a day. By 1930 the amount had risen to 126 litres. Water use at home has increased even more in recent years because more people have appliances such as washing machines and dishwashers and are using hosepipes and power showers. Each person in England and Wales now uses an average of between 135 and 150 litres of water every day."
"Farmers need lots of water for growing crops, especially when the weather is hot and dry. Factories also use large amounts of water for making things."
How much water do you think is used to make some of our foods and everyday items?
Let's look at some examples:
-A slice of white bread: 40 liters
-1 pint of milk: 600 litres
-A burger: 2400 litres
-1 kg of cheese: 5000 litres
- ...
In conclusion I think that we should be very careful not to was te or pollute water .
I suggest you to visit the website because it's very interesting (there is also a rough guide to the amounts of water used in different activities at home).
Let me know if the values are correct according to your lifestyle or not! :-)
