Various human activities, such as burning fossil fuels and deforestation, release carbon dioxide (CO2) into the atmosphere. This CO2 is a greenhouse gas that, when absorbed by the oceans, leads to a process called ocean acidification.
When CO2 dissolves in seawater, it reacts with water molecules and forms carbonic acid. This reaction increases the concentration of hydrogen ions (H+), resulting in a decrease in pH levels and making the seawater more acidic. This decrease in pH is a key characteristic of ocean acidification.
As the ocean becomes more acidic, it disrupts the delicate chemical balance that many marine organisms rely on for survival and growth. Organisms like corals, shellfish, and phytoplankton use calcium carbonate to build their shells or skeletons, but increased acidity hampers their ability to do so.
Ocean acidification also impacts the growth and development of marine plants and animals. For instance, changes in pH levels can affect the ability of larvae from certain marine species to form strong shells or skeletons. Additionally, acidified waters can disrupt the metabolism and reproductive processes of many marine organisms.
The consequences of ocean acidification extend beyond individual organisms. Entire ecosystems, such as coral reefs, face threats due to increasing acidity. Coral reefs provide habitat for numerous species and are vital to marine biodiversity. However, the more acidic conditions make it challenging for corals to build and maintain their calcium carbonate structures, resulting in coral bleaching and degradation of reef systems.
Moreover, ocean acidification can have cascading effects on other marine organisms and food webs. For example, changes in the growth and survival rates of phytoplankton, a primary food source for many marine species, can disrupt the entire food chain, impacting fish populations and ultimately affecting human communities that rely on seafood for sustenance and livelihoods.
In conclusion, the rise in carbon dioxide emissions contributes to ocean acidification, which alters the chemistry of the oceans and poses significant threats to marine life and ecosystems. Understanding and addressing the causes and impacts of ocean acidification are essential for the long-term health and sustainability of our oceans.
Carbon dioxide (CO2) is a greenhouse gas that is released into the atmosphere through various human activities, such as burning fossil fuels and deforestation. A significant portion of this CO2 is absorbed by the oceans, leading to a process known as ocean acidification.

The consequences of ocean acidification extend beyond individual organisms. Entire ecosystems, such as coral reefs, are threatened by the increasing acidity. Coral reefs provide habitat for countless species and are a crucial part of marine biodiversity.

Understanding and addressing the causes and impacts of ocean acidification are crucial for the long-term health and sustainability of our oceans.
Carbon affects ocean acidification by increasing the concentration of carbon dioxide in the atmosphere. When carbon dioxide dissolves in seawater, it reacts with water molecules to form carbonic acid, which lowers the pH of the ocean. This decrease in pH makes the water more acidic, impacting marine organisms like corals, shellfish, and plankton, as it hinders their ability to build and maintain their shells or skeletons. Additionally, ocean acidification can disrupt the food chain and ecological balance in marine ecosystems.
