In this case it doesn't, you're stealing luxury items that are playing a huge huge role in water consumption. It's like 91 liters of water per day per tree.
And an academic study focusing on global implications for water scarcity from the growth in avocado production says that that growing avocado requires “four times more water than the production of a kilo of oranges and ten times of that of a kilo of tomato”.
Oranges and tomatoes are also mostly water by weight. If you were to compare the water mass percentages of each of those fruits, you'd probably find the avocado is more efficient in calories and nutrients per water usage.
wait but would paying for it be better? does it just goes into the pocket of the store owner and gives them more motive to sell avocados? anyways i feel bad for enjoying avocados now sob
