Avocado? Avocadon't - they come at a high price

An article in the Guardian which has been picked up and discussed in lots of places talks about the demand for water in a region of Chile where avocados are grown.

It takes two thousand litres of water to produce just one kilo of avocados. According to the Water Footprint Network, this is four times the amount of water needed to produce a kilo of oranges, and 10 times what is needed to produce a kilo of tomatoes.
