Answer:
Ocean acidification: Ocean acidification refers to the decrease in the pH of ocean water.
The pH of ocean water decreases due to the increased in the carbondioxode emissions in the atmosphere because of the burning of fuels. This carbondioxode is dissolved in the ocean water and forms carbonic acid. This carbonic acid is responsible for increasing the pH of ocean water. In one and half century, there is 30% increase occurs in the acidity of ocean water.
As a result in the attempts to reduce the amounts of carbon dioxide and methane, green house gases will lessen and the ozone layer will slowly stop being damaged. Global Warming may also calm down as the main cause for global warming is the exposure of Greenhouse gases to the ozone layer.
