Icebergs melt - this is a natural phenomenon that has been going on for thousands of years. And when they melt, they add fresh water to ocean water. There is scientific concern that too much fresh water melting into salt ocean water may have long term effect such as raising sea levels, and/or making natural ocean currents, such as the Gulf Stream, behave differently. Therefore preventing too much ice melting into the sea is a good thing. However, compared to the total amount of iceberg ice melting every year, the ice we capture for GLACE Rare Iceberg Water is literally a drop in the ocean.
