Both the banana and pineapple plantations took steps to ensure that they were acting in a sustainable way. Both plantations were organic, so they don’t use synthetic pesticides, and making sure their crops are not contaminated by any chemicals. Both plantations also use parts of their plants as compost that then gets turned into fertilizer for future plants. 

Both of the plantations have specific issues with the crops they use. The pineapple plantation use a monocrop, pineapple is the only plant they grow, so they are entirely dependent on the harvest of pineapples, and they have to plant legumes every three years so the soil can have its nitrogen replaced. The legumes and old pineapple plants get ground into the soil, and they provide nutrients for the next batch of plants. The banana plantation plants cavendish bananas, which are all genetically identical, so they are extremely vulnerable to disease and pests. They mitigate this by often checking for diseases on the bananas. 

If I was a plantation worker, I would rather work on a coffee plantation. The work is only part of the year, so they don’t need to spend the whole year on the farm. Coffee plantation workers also get to work in the shade and in close proximity to other workers, which I would find much more enjoyable.
