Decline in Top of the Foodchain Predators

I read this article about the decline in apex predators such as; sharks, tunas, swordfish, and marlins. Over time fishing has led to a 90-per-cent decrease in top predators since the 1950s. The scientists found that it first started in coastal areas of northern countries, then expanded to the open ocean and to the southern hemisphere. The decline in these predators is changing everything about marine ecosystems systems all over the world. There is a high market demand for these fish and with out stricter fishing regulations the problem will only get worse.
