Suzanne Harrington: Here's why I ordered the non-sustainable avocado meal

What used to be markers of impecuniosity are now becoming markers of sustainability

It takes 2,000 litres of water to produce one kilo of avocados 

Eating dinner at a Mexican street foody place, the menu offers a sustainable alternative to guacamole, made from locally-grown fava beans instead of imported avocados. One kilo of avocados needs 2,000 litres of water to produce, a bit like almond milk - to grow one single solitary almond takes 5 litres of water. Which is why we are all drinking oat milk now – it needs six times less water than almond milk to produce.

These are the kind of sums that have become part of our brain’s daily workout. Through climate change necessity, more mindful consumption has been slowly replacing the mindless kind, the kind that limbic capitalism has long promoted.
