Krill are small shrimp-like crustaceans which live in oceans around the world - mostly in cold water. They feed on plankton and marine algae, making them high in Omega-3. In recent years there has been a growing demand for krill oil as an alternative to fish oil for Omega-3 supplements.
Krill are found in large groups throughout the world's oceans. However, Antarctic Krill are often specifically targeted for the production of krill oil. They are found in large numbers in the Antarctic and the clean waters result in a low level of environmental toxins, making them a tempting target for krill-fishing companies.
A recent investigation by Greenpeace found that krill-fishing companies are becoming more active in the Antarctic, due to the increasing demand for krill oil. This could seriously damage the delicate eco-system of the Antarctic, as krill are a critical food source for penguins, whales, seals, sea-birds and many more. If the krill disappear from these waters, so will the incredible wildlife that depends on it to survive.
