How an Ocean becomes Acidic

In this model we can see a factory emitting carbon gasses. ¬†The burning of the fossil fuels produces a gas called carbon dioxide which is released into the ¬†atmosphere. The oceans absorb about 26% of this gas to achieve equilibrium and this is causing the oceans pH levels to change. Carbon dioxide (CO2) combined with water (H2O) changes the composition of the water, causing H2CO3 which is carbonic acid (National Resource Council). This acid is causing the ocean ecosystems to change with it. This carbonic acid is changing an animals way of making shells. There are animals known as cephalopods that have external shells and the carbonic acid has an effect on them like radiation has on humans, they can’t make their shells properly and without them, they can’t protect themselves.
