North America and the UK don't produce avocados, thus they're imported. The further a meal is from its source, the bigger the effect.
First, avocados' energy, water, fertiliser, and pesticides have environmental implications.
Tom Cumberlege, associate director of Carbon Trust, says packing, processing, shipping, and cooling avocados have further implications.
They need twice as much water as oranges and are typically produced in water-scarce places.Avocados need a lot of water, aggravating Mexico and California's droughts and
heatwaves, making it tougher to cultivate the fruit, leading to more deforestation to farm it, etc.
Since becoming a superfood and breakfast addiction, worldwide production has increased to satisfy demand.
