VOICED: Ocean acidification threatens marine life

The video discusses the impact of rising CO2 levels on ocean acidity, particularly around the Norwegian island of Spitsberg. Researchers in the Arctic are studying this phenomenon by injecting CO2 into ocean water to simulate future conditions. The increased acidity is harming marine life, slowing the calcification of corals and mollusks, and threatening biodiversity. Sea snails, crucial to the Arctic food system, are at risk of losing their shells, which could disrupt the ecosystem and reduce their role in CO2 absorption, posing a threat to efforts against global warming.

What is the main cause of the increasing acidity in the oceans around Spitsberg?

• Rising levels of CO2

• Oil spills

• Overfishing

• Plastic pollution

What is the purpose of the researchers' experiment in the fjord near the North Pole?

• To study the effects of CO2 on enclosed water bodies

• To measure the temperature of the ocean

• To track the migration of whales

• To clean the ocean water

How do researchers simulate future ocean conditions in their experiment?

• By adding pollutants

• By increasing water temperature

• By introducing new species

• By injecting CO2 into the ocean

Which marine species is particularly threatened by ocean acidification?

• Sharks

• Sea turtles

• Sea snails

• Dolphins

Why are sea snails important in the fight against global warming?

• They produce oxygen

• They are a food source for humans

• They clean the ocean floor

• They help sequester CO2 in their shells
