The carbon dioxide emissions (carbon footprint) caused by our personal behavior is driven to a large extent by the type and quality of our food. The amount of greenhouse gases caused by the production of food differs very much from one food type to the other. With the amount of food that is wasted in the average household, this carbon footprint rises significantly. 2
In Australia, 4,000,000 tonnes of food is wasted each year. If you add up all the food Australia wastes each year, it would be enough to fill 450,000 garbage trucks. When you throw out food, you also waste the water, fuel and resources it took to produce and get the food to your plate. When food rots with other organics in landfill it gives off the greenhouse gas methane, which is 25 more times more potent than carbon pollution that comes out of your car exhaust. 1
So should we be crying over spilt milk? The production of 1L of Milk causes about 0.9kg of CO2. The same quantity of CO2 is released when you burn about 4 liters of petrol. 1,000 gallons of water is required to produce 1 gallon of milk and a farm with 2500 dairy cows produces the same amount of waste as a city of 411,000 people.3
Milk production is killing our planet and with its short shelf life liters are going to waste each year. With so many delicious, healthy and sustainable milk choices is there really any reason to keep consuming?
