How does receding glaciers in Antarctica have some unexpected positive effects?

    In fact, the open area that the glaciers have left behind have become a place where certain phytoplankton can flourish, and when these die off they take carbon with them, so that it is trapped for large periods at the bottom of the ocean. In this way, the receding glaciers have created a major new carbon sink. However, the phytoplankton are a huge part of many food webs, including that of the blue whale, and any changes in their population is potentially worrying. It will be important to see how the area continues to change over time.
