NEW TPO 5 Why does the author mention "adaptive strategies for marine life" in the last paragraph?

展开

Ocean Acidification

Ocean acidification is a significant environmental issue resulting from increased carbon dioxide (CO2) levels in the atmosphere. When CO2 dissolves in seawater, it forms carbonic acid, which lowers the ocean's pH. This change in acidity affects marine life, particularly organisms with calcium carbonate shells, such as corals, mollusks, and some plankton species.

Coral reefs are among the most affected by ocean acidification. The acidic water makes it difficult for corals to maintain their calcium carbonate skeletons, leading to weakened structures and increased vulnerability to erosion and breakage. This process also disrupts the symbiotic relationships between corals and algae, further harming reef ecosystems.

Mollusks, including oysters and clams, struggle to develop their shells in acidic conditions, which can lead to reduced survival rates and impact the aquaculture industry. Plankton, at the base of the marine food web, also faces challenges, as their shells become more fragile, affecting their ability to reproduce and survive.

Efforts to mitigate ocean acidification include reducing CO2 emissions, protecting marine areas, and researching adaptive strategies for marine life . Addressing this issue is crucial for preserving biodiversity and maintaining the health of marine ecosystems.

5.Why does the author mention "adaptive strategies for marine life" in the last paragraph?

A. To emphasize the importance of reducing CO2 emissions

B. To suggest that current mitigation efforts are ineffective

C. To argue that protecting marine areas is unnecessary

D. To highlight potential solutions to help marine organisms cope with ocean acidification
