Our love of seafood, and sushi in particular, comes at a much higher price than many of us bargained for – a price far greater than just dollars.

A new study from World Wildlife Fund's "Living Blue Planet Report" suggests that the population of fish in our oceans is just 50 percent of what it was 50 years ago. A drastic decline by any standard.

The study tracked just over 1,200 species of marine wildlife, with particular concern surrounding yellowfin tuna and mackerel, which have both seen a particularly drastic decline of nearly 75 percent. While overfishing has played a big role in the population drop, environmental factors — like climate change and mangrove deforestation — have also had a hand in this.
