The rise in ocean acidity is a direct result of increased carbon dioxide levels in the atmosphere. To protect marine life, we must significantly reduce our carbon emissions.
Which of the following, if true, most helps to justify the author's conclusion?
- Curbing carbon emissions is the surest available means of slowing the ongoing increase in ocean acidity.
- Ocean acidity has, over the past few years, climbed to its highest measured point in several centuries.
- Numerous marine species across many ocean regions are already showing visible stress from rising acidity.
- Factors besides atmospheric carbon dioxide also strongly influence the overall chemistry of ocean water.
- Cutting carbon emissions alone would fully restore the oceans to their pre-industrial chemical balance.
