Looks like the main issue is that they tend to be grown in areas that may be prone to drought, so there's a concern that they may deprive the community of water.
"Monoculture crops like avocados wind up drawing all the nutrients from the soil, slowly degrading it year after year. This makes the soil less fertile over time until it is no longer viable for growing".
So yeah, buying avocados is pretty much a sin against nature.

That's just irresponsible farming. It can happen with almost any crop.
