No surprise here, but a recent article at phys.org talks about over-consumption on a global scale, how we’re consuming more than this planet can produce. Think of it in terms of personal finance…we’re spending more than we’re making each money, and out savings account is going to run out (with no interstellar ‘banks’ to extend us credit!).
What I really found interesting though was the chart below, that illustrates how the carbon footprint of different food varies. It’s amazing how bad cows are for our environment, especially compared to other meat options like pork or chicken!
