Storyboard Text

  • Hi Giada, I saw a documentary about ocean acidification. Do you know what it is about?
  • No, mom ..... tomorrow I will ask my science professor.
  • Hi Giada: acidification is the phenomenon that describes the continuous increase in the acidity of the oceans due to the absorption of carbon dioxide from the atmosphere
  • Good morning Prof, what is ocean acidification?
  • How does it happen?
  • Acidification occurs when seawater reacts with the CO2 absorbed by the atmosphere, producing more acidifying chemicals and reducing important minerals, such as calcium carbonate, which ensure the survival of marine organisms.
  • The consequences are many. The coral reefs die from the bleaching of the corals, the shells and the limestone shells of the crustaceans are melted and many fish die.
  • Which are the consequences?
  • what can we do?
  • For open ocean and deep sea areas, sustainability can be achieved only through increased international cooperation to protect vulnerable habitats.
  • Making small changes in our lives, like taking public transport and unplugging electronics to save energy. These actions reduce our carbon footprint, a factor that contributes to rising sea levels and ocean acidification.
  • In our daily life?(1)
  • From tomorrow we will all ride a bicycle !!!(2)
