It takes the same amount of energy (480 kJ) to manufacture one plastic bag as it does to bring one litre of water to boil. A Finnish person consumes 55 plastic bags a year, and 300 million plastic bags are consumed annually in Finland. Expressed in boiling water, the binding energy of manufacturing these is equal to how much water would fit in 400,000 pools, of the same size, as the one in Lappeenranta swimming hall.

### This is how much water is needed to make

- A cup of coffee: 140 litres of water
- One kilo of beef in the oven: 15,500 litres of water
- An apple for a packed lunch: 70 litres of water
- A T-shirt: 2,700 litres of water
- 1 kg of rice: 3,400 litres of water
- 1 kg of beef: 15,500 litres
- 1 kg of cheese: 5,000 litres
- A slice of bread: 40 litres
- 1 A4 sheet of paper: 10 litres
- 1 litre of milk: 1,000 litres
- 1 kg of chicken: 3,900 litres
- A cup of tea: 30 litres
- A glass of beer: 75 litres of water
- 1 kg of wheat: 1,300 litres
- 1 kg of pork meat: 4,800 litres

### Water hidden in food

- 2 dl of milk = 200 l of water
- 2 dl of apple juice = 190 l of water
- A cup of coffee = 140 l of water
- 2.5 dl of tea = 35 l of water
- 1 potato = 25 l of water
- 1 bag of crisps = 185 l of water
- 1 orange= 50 l of water
- 2 dl of orange juice = 170 l of water
- 1 dl of rice = 340 l of water
- 1 kg of beef = 15,000 l of water
- 1 egg = 135 l of water
- 1 hamburger = 2400 l of water
- A cup (125 ml) of virtual (hidden) water is 140 litres
