Salt industry on Bonaire (Netherlands Antilles) - stock photo

Much of Bonaire's Southern half has been made into a giant system of ponds and pools which take seawater and allow incrimental evaporation of the water until the only remaining product is sea salt. Bonaire's solar salt works produces 400,000 tons of industrial grade salt per year primarily using wind to operate windmill-driven pumps and gates and the sun to evaporate the collected seawater.
