Narwhals have been listed as “Nearly Threatened” since 2008. Very few laws have been proposed in attempts to protect this interesting species. In an effort to support conservation, the European Union established an import ban on tusks. Narwhals are becoming extinct for three main reasons. The primary catalyst for the series of events that have led to decrease narwhal populations is unprecedentedly rapid climate change. Thousands of years of evolution have prepared an Arctic species like the narwhal for life on and around the sea ice. Because of climate change, this ice cover has dramatically decreased in both extent and thickness, at a rate far too quick for a species to adapt. A narwhal relies on sea ice for a place to feed and a place to take refuge—occasionally even a place to hide from predators. An additional result of climate change is the reduction in the population of the Narwhal’s primary prey, the Greenland halibut.
