This especially happens for shrimp. In Thailand, farmers are lured in by high short term profits for farming shrimp, so they clear a lot of biodiverse mangrove swamp. When they realize that shrimp are a bitch to raise in densities that make it profitable, they end up selling the land to professional shrimp farmers, who grow the shrimp with lots of antibiotics and specialized shrimp feed. After a while, the shrimp parasites and diseases are endemic to the land, so the pros just leave and find someplace else cheap to buy. Meanwhile, the land is ruined, as shrimp live in brackish water, the salted land is no good for agriculture, and it takes decades for the mangroves to grow back again.
