Mainers have strong cultural, historic and economic ties to the ocean. The health of the ocean is critical to our way of life. Ocean acidification is a growing problem that could damage the health of the ocean and have drastic consequences for Maine’s coastal economy.
Ocean acidification results when there is increased carbon dioxide in the atmosphere. As the amount of carbon dioxide in the atmosphere goes up, a large proportion of it – up to 40 percent – gets dissolved in rainwater. From here it ends up in lakes, ponds, rivers and ultimately the ocean.
In addition to the increased atmospheric carbon dioxide, nutrients in the runoff from the land, like fertilizer, also increase the amount of carbon dioxide entering the ocean. The increased carbon dioxide reacts with the water to form carbonic acid, making it more acidic.
