Amazing Co2 facts

As we all know, concrete produces about 1 metric tonne of C02 for every tonne of product created. This, as we all know, is BAD. But, I just noticed that Tesco milk cartons have a C02 footprint indicator on the side. Did you know that 568ml of milk - which is about 500 grammes (i'm sorry my research hasn't extended to finding out the Specific Gravity of milk) generates 900 grammes - 900!! - of C02. That is really bad. BAD.

So, put cement in your tea, or stop building your foundations out of milk, or we all up the swanny.
