"We are trying to target the niche market for healthy foods and products," says former fisherman Edward Kean, an iceberg hunter. For 20 years, he has been cruising the North Atlantic aboard his fishing boat to retrieve chunks of ice to melt and sell the water to local traders. Customers include manufacturers of vodka, cider, liquor, beer, cosmetics, but also companies that bottle water. (Photo by Johannes EISELE / AFP) (Photo by JOHANNES EISELE/AFP via Getty Images)
