Which of the following statements about the effects of pollution on marine ecosystems is true?

Burning fossil fuels releases carbon dioxide into the atmosphere. Some of that carbon dioxide dissolves in ocean water and forms carbonic acid, which lowers the water’s pH and makes it more acidic. Therefore, the true statement is that burning fossil fuels causes a decrease in ocean-water pH. Warm-water pollution can affect marine ecosystems, and pollution can contribute to algal blooms, so the other statements are not correct.
