Ocean acidification

 Why is up to 90 % of the coral around Florida bleaching and in the end stages of dying?

• It is old and new coral is replacing it
• It is not used and not needed anymore
• The coral is responding to the increasing Ocean temperatures
• None of the above

 If carbon dioxide emissions continue to fuel global warming, most of the coral reefs could be dead by 2050. Why should I care?

• Because most of the world relies on the Ocean as a major source of food, also economic disaster would happen
• Because the coral reefs are the key barrier to protect against storming seas.
• Because jobs and the tourism industry would be severely affected as well as worldwide starvation.
• All of the above
