The ocean is the largest ecosystem on Earth, it is basically the planet’s life support system. Oceans make about half of the oxygen we breathe . Oceans produce a lot of  the animals people eat. Living oceans also absorb carbon dioxide from the atmosphere and reduce climate change impacts. But at the rate humans are going they are starting to overload the oceans with carbon dioxide making it toxic for our corals. We are killing our corals at a rapid pace, over 35% of the worlds corals have been killed since 1975. We need to start taking a stand and start reducing carbon emissions so that we can save our oceans a keep them from getting any worse.
