Explain two different perspectives of different marine industries on the carbon cycle.
allochka39001 [22]

Answer:

The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.

Hope it helps!
