No More Nemo?
By: Akhila Srinivas
A lot of you may think that carbon pollution ONLY warms the climate—wrong. Carbon pollution is a MAJOR player in acidifying our Earth’s oceans right as we speak. So what even is ocean acidification? Is the ocean lowering in pH? Well, as a matter of fact, yes. Our oceans absorb almost 1/4 of the carbon dioxide that is emitted into our atmosphere. Every day, this is around 22 million tons of carbon dioxide from factories, power plants, cars, and other anthropogenic sources. The oceans are in serious trouble. But why does this matter in the long run?
Ocean acidification causes harm to creatures with calcium carbonate in their shells or skeletons, making it difficult for creatures like mollusks, crabs, and corals to survive. An acidic ocean robs seawater of the compounds these creatures need to build their shells and skeletons, impairing their growth. In addition, increased acidity makes it extremely difficult for clownfish (aka Nemo) to sense predators and for sharks to hunt for prey. All of these effects ultimately lead to extreme changes in oceanic food webs, leading to certain population collapses in various aquatic species. Two important ecosystems, coral reefs and polar regions, are targets of ocean acidification. Coral reefs can’t develop in acidity, causing coral bleaching and affecting species of fish that rely on coral for shelter and food. In polar regions, many marine plankton will suffer and pteropods, an important food source for salmon, herring, and cod fish, cannot survive in such conditions. These changes can affect large animals like whales and sea otters who rely on these food sources for survival.
Now comes the answer to everybody’s question: How does this affect us?
Communities who depend on the fishing industry experience many detrimental effects of ocean acidification, as they are losing an important food source as fish species cannot survive in increasing acidic conditions. In Alaska, where over half of seafood is caught, fishers are suffering from rapid acidification that is endangering millions of livelihoods and jobs.
We NEED to reduce carbon pollution immediately! This is a serious issue that can have major transformations in our lives, aquatic ecosystems, and the entire planet. Carbon emissions must be controlled now, or future generations may never see Nemo ever again.
How can we control carbon emissions other than reducing the burning of fossil fuels?
Is ocean acidification even an important issue to be discussing?
What are some ways ocean acidification can impact your life?

Because coastal states produce only a small proportion of CO2, there is little incentive for states to reduce emissions. However, some changes may be both beneficial and profitable. For example, increasing urban density will both decrease vehicle transportation (which decreases emissions) and increasing tax revenues.
