Pineapples: luxury fruit at what price?

Its really sad to see the effect of large corporation's greed on the environment and their workers.  The impact on the environment is especially scary since the pesticides used in the farms have reached the ocean and nearby water sources for the surrounding villages.  It was interesting to see the alternative to conventional farming.  But what made organic farming unecouraging was that only 1/4 of the crops are sold as fair trade, while the other 3/4 were sold as conventionally grow, not rewarding farmers that choose to do the right thing, or being pono.  The exploitation of local Costa Rican workers and illegal immigrants from Nicaragua made me think of recent news in Hawaii regarding Aloun farms.  The owners of Aloun farms were accused of trafficking workers from Thailand to work on their farms.  They underpaid them and even went as far as taking away their passports so they couldn't return home.  This also made me think of how my grandmother used to work in the Dole pineapple fields and canery here during WWII.  Were the same pesticide practices used? Are today's "Maui Gold" pineapples part of the same disasterous cycle? Its amazing how greed can make people disregard the impact they have on people and the environment.
