Arctic waters increasingly vulnerable to foreign species

When most people think of climate change, they picture polar bears, not zooplankton. Zooplankton are a huge group of water organisms which range from microscopic crustaceans to jellyfish and live in both fresh and salt water. Just about everything in the ocean eats zooplankton, from tiny fish to huge whales. In other words, they’re important to the Arctic food chain. But that food chain is about to change dramatically because of climate change and increased shipping traffic, according to some recent studies. [email protected]  18:00
