What is ocean acidification?

Ocean acidification is when the pH level of the ocean decreases, the ocean becomes more acidic because it absorbs carbon dioxide from the air. 

What causes ocean acidification?

The main cause of ocean acidification is increased levels of carbon dioxide. The burning of fossil fuels like coal, oil, and gas, releases CO2 into the air. A big portion of the CO2 is absorbed by the ocean. 

How does it affect animals and impact humans?

Ocean acidification can affect animals by affecting their growth and survival. It can disrupt the balance of the ecosystem, limiting their food sources. For humans, ocean acidification can limit their sea food supply and affect tourism activities that are centered around healthy marine ecosystems.
