Dans le domaine des sciences de l’environnement, comment les activités anthropiques contribuent-elles au phénomène d’acidification des océans, et quelles sont ses implications potentielles sur la biodiversité marine ?<end_of_turn>
<start_of_turn>model
Anthropogenic activities, particularly the burning of fossil fuels, release excessive carbon dioxide into the atmosphere. When absorbed by oceans, it forms carbonic acid, leading to ocean acidification. This can harm marine life, especially calcifying organisms like corals and mollusks, threatening marine biodiversity.

Ocean acidification is the decrease in the pH of the Earth's oceans. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO2) levels exceeding 410 ppm (in 2020).<end_of_turn><eos>
