Put a Stop to Ocean Acidification
By Rahul Kumar
Throughout history, the release of CO2 by human activity has increased vastly. Many environmental problems are caused by increased pollution, but one problem is typically overlooked: Ocean Acidification. In the past 200 years, the pH of surface ocean waters have reduced by .1 pH. The pH scale works like the Richter Scale, meaning it is logarithmic. A 0.1 pH decrease doesn't seem like a lot, but it actually results in a 30% increase in acidity.

The Cycle of Ocean Acidification
Since the industrial era, the ocean has approximately absorbed 525 billion tons of CO2 from the atmosphere, which is decreasing its pH. The decreased pH is harmful to a lot of the marine life in the ocean. For example, the shells of some animals dissolve in acidic seawater. The pH also causes chemical reactions, making carbonate ions less abundant. Carbonate ions are essential to the creation of coral skeletons and sea shells. Therefore, not only does the acidic water dissolve the shells, but it makes the shells harder to be produced. The animals that depend on these shells will die off without them. One animal, the Pteropod, has been affected greatly by shell deterioration, and is slowly being removed from the marine ecosystem. This would disrupt the entire ecosystem, causing a devastating chain of events.
Pteropod
Scientists are already working hard to solve this problem. NOAA is collecting carbon meaurements and performing research expeditions to study how the carbon dioxide is changing the ocean chemistry. As for the global population, we must take an initiative to reduce our CO2 emissions to help slow down ocean acidification. Fossil fuel consumption must be lowered, and we should strive to use environmentally friendly energy sources as much as possible.
Do you believe ocean acidification is a big enough problem to significantly reduce our carbon emissions?
What do you think you could do to reduce carbon emissions in your life?
Why do you believe we should strive to use more environmentally friendly energy sources?
