I think I've just found my new favourite cartoon! This brilliant illustration was sent to us by the insightful and very talented Donn Pattenden (thanks Donn!).
This is one issue that really stirs me up. The meat and dairy industries are huge water guzzlers. The UN's Food and Agriculture Organisation estimates that one glass of milk takes roughly 200 litres of water to produce. That's almost 3 days worth of showers! But that's nothing compared to the 100,000 litres of water that David Pimentel, a water resource specialist, says is required to produce just 1 kilo of beef!
In a country as dry as Australia, this sort of squandering of water just doesn't make sense. I live in Brisbane, where water shortages are a real threat (just like many of our other cities). We've been told to keep our domestic water usage below 140L of water per person per day...
I'm all for water conservation at home. In fact, we've just installed a new rain water tank :-) ... but when 70% of global water usage is for agriculture, it seems like what we eat and drink would be a smart place for us to start looking at how we can save water.
