Mercury in the oceans increasing

Researchers from Wright State University have concluded that mercury levels in oceans are rapidly increasing. The article states that the ocean contains between 60,000 and 80,000 tons of mercury pollution. They also found that in ocean depths of 300 feet or less mercury levels have tripled since the Industrial Revolution. This is a huge problem because large amounts of mercury are poisonous to humans. If mercury levels in oceans continue to increase at the levels they are, some fish may not be edible by humans. Most mercury pollution comes from human activities such as burning coal. A simple solution to this growing problem would be to limit the amount of coal that can be burned in a given time. Barriers to this solution include human cooperation. Some people would not be willing to give up small amounts of power to make this work. I believe this problem will only grow in the coming decades. Humans really need to step back and see what they are doing to the environment and think about the future.
