1. Understanding Ocean Acidification: A Threat to Marine Ecosystems

Ocean acidification refers to the ongoing decrease in the pH level of the Earth’s oceans, caused by the absorption of carbon dioxide (CO2) from the atmosphere. According to the National Oceanic and Atmospheric Administration (NOAA), the ocean absorbs about 30% of the CO2 released into the atmosphere, which leads to a series of chemical reactions that reduce seawater pH. This process has profound effects on marine life, particularly shell-forming organisms and coral reefs, which are vital to many tourism industries.

1.1. The Chemistry Behind Ocean Acidification

When CO2 is absorbed by seawater, it reacts to form carbonic acid (H2CO3). This acid then dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+). The increase in hydrogen ions lowers the ocean’s pH, making it more acidic. This increase in acidity reduces the availability of carbonate ions (CO3^2-), which are essential for marine organisms to build and maintain their shells and skeletons.

1.2. Impact on Marine Life

The consequences of ocean acidification for marine life are extensive and varied. Shell-forming organisms like oysters, clams, and corals struggle to build their shells and skeletons in more acidic waters. According to a study published in Nature Climate Change, many marine species exhibit reduced growth rates, reproductive success, and overall survival rates due to ocean acidification. This can lead to a decline in populations and shifts in species distribution, affecting the entire marine food web.

1.3. Coral Reefs at Risk

Coral reefs are particularly vulnerable to ocean acidification. These underwater ecosystems are biodiversity hotspots, providing habitat for a quarter of all marine species and supporting the livelihoods of millions of people through tourism and fisheries. Ocean acidification reduces the calcification rates of corals, making it harder for them to build and maintain their structures.
