And whilst we can call on the governments at Copenhagen to commit us all to a future of lower emissions, the only real difference we can make in our lifetimes is through reducing meat and dairy intake and becoming vegan. The logic is simple - greenhouse gases are principally carbon dioxide and methane. Carbon dioxide generated by energy consumption and transport takes about 120 years to cycle out of the atmosphere. Methane, mostly generated by animals bred for human consumption, is nearly thirty times more heat retaining than carbon dioxide but takes only eight years to cycle out of the atmosphere. 20% of the greenhouse gases generated are attributed to meat and dairy consumption..
So whilst we can point fingers at our government and expect someone else to do it for us, we all have the option of taking control and doing our bit by improving our health and that of the planet by going vegan.
