Question

What solution would best help to reduce the bleaching of coral reefs?

O A. introducing non-native marine species to the coral reefs
O B. reducing the amount of carbon dioxide released into the atmosphere
O C. planting more algae on the coral reefs
D. releasing large amounts of calcium carbonate into the oceans

Answer 1

B. Reducing the amount of carbon dioxide in the atmosphere, as it exchanges with the ocean and is making it more acidic. Non-native species could become invasive, algae is generally not reabsorbed by the corals after bleaching, and calcium carbonate, although necessary for corals, would not reduce bleaching and could potentially contribute to it.
