The avocado has become something of a celebrity in the food world, and its popularity has seen a massive boom in its production, largely in Mexico.
But some have started to turn away from the versatile fruit.
Australia's trendy cafes have embraced the avocado, on toast, in salads, or in that Mexican staple guacamole.
It's a fashionable food.
Global avocado production has doubled over the last 20 years.
Australians have lifted their avocado consumption to 3.8 kilograms per person annually.
But now some chefs are turning away, citing its impact on the environment.
Popular Mexican restaurants in the UK, US and Canada are offering guacamole made from peas, or zucchini, or Jerusalem artichokes instead.
So what's the problem? Some reports suggest a single avocado needs hundreds of litres of water to grow.
Honor Eldridge from the conservation charity Plant Life says that's a big issue.
