How is climate change affecting deep-sea eco systems?

    The is much evidence that climate change is affecting deep-sea ecosystems.  The area known as abssyl plains deep in the ocean’s depths covers about 60 percent of the Earth’s surface.  Scientists used to think that ecosystems at these depths were relatively stable and independent.  However, over 18 years worth of research, a marine ecologist called Ken Smith (of the Monterey Bay Aquarium Research Institute) has found that these ecosystems can change dramatically over short periods of time.  Organisms that live at these depths depend on organic matter slowly drifiting down from the surface of the ocean, and climate change causes variation in this food supply.
