One of these issues that came up was our consumption of beer. I don't have any statistics, but based on the mass worldwide consumption beer, I wondered how many acres of land are used to produce the Barely and Hops that goes into making one of our oldest and most favoured beverages. People talk about food crises and the lack of food available to people in the 3rd world. Well, how fair is it that we grow what is probably hundreds of thousands of acres of barely/hops crops, and extract thousands of gallons of water to produce a beverage that leaves us stupefied and dehydrated, and sadly in some cases, even dead.
I'm not trying to be one of those moral anti-alcohol straight edge purists, seeing as I drink beer and other alcoholic beverages all of the time - I was just trying to work out the actual logistics of drinking beer when when we focus so heavily on other environmental issues. Just some food for thought.
