Top Pro & Con Arguments
Ocean acidity levels are increasing at an unprecedented rate that can only be explained by human activity.
As excess human-produced CO2 in the atmosphere is absorbed by the oceans, the acidity level of the water increases. Acidity levels in the oceans are 25-30% higher than prior to human fossil fuel use.  The US Government Accountability Office (GAO) said oceans have absorbed about 30% of the CO2 emitted by humans over the past 200 years, and ocean acidity could rise approximately 100-200 percent above preindustrial levels by 2100. 
The World Meteorological Organization said the current acceleration in the rate of ocean acidification “appears unprecedented” over the last 300 million years.  High ocean acidity levels threaten marine species,  and slows the growth of coral reefs.  The Convention on Biological Diversity said “it is now nearly inevitable” that within 50-100 years continued human-produced CO2 emissions will increase ocean acidity to levels that harm marine organisms and ecosystems.
