In the ocean Co2 levels are increasing which will endanger many species unless we do something about it. This is called ocean acidification. Ocean acidification is mainly caused by the burning of fossil fuels. If we stop burning so many fossil fuels it ’ll help this problem because burning them causes carbon dioxide in the atmosphere end up in the ocean. This makes the water more acidic and less hospitable for animals to live in. Over time co2 reduces calcium carbonate and this effects shell which will dissolve. Crab and lobster shells will dissolve don’t you want to be able to eat them if this problem continues, probably won’t. The acidic water from all this makes the base of the food web die because there skeletons wont form in those conditions. This causes all the animals who eat them in trouble cause if they die out what will they eat?
