GS 3 ||Environment || Climate Change ||Acidification
Why in News:
- Water present in the Ocean is gradually becoming acidic but marine vegetation can mitigate this acidification of oceans of the world.
Uof California’s Research:
- pH value of ocean water is gradually reducing below 7, which is the indication of any liquid becoming acidic (if the ph value of any liquid is above 7, it becomes alkaline).
- Reason of this regression is increased amount of CO2 in the environment and this CO2 reacts with the H2O and thus forming Carbonic Acid (H2CO3)
- Marine plants and seaweeds in shallow coastal ecosystems can play a key role in alleviating the effects of ocean acidification, and their robust population in shoreline environments could help preserve declining shellfish life, according to a study by University of California.
- The marine plants in the vicinities of oceans and seas they absorb the redundant CO2 of the area and use them in their botanical activity and thus creating less intense carbonic acid.
- In a new study on the Pacific Coast, determined that marine plants and seaweeds decrease the acidity of their surroundings through photosynthesis.
- Their findings suggest that maintaining native seawater vegetation could locally lessen the acidifying effects of rising CO2 levels on marine animals who are sensitive to ocean pH, which has declined since preindustrial times.
- About 90 percent of fishery catch comes from coastal ecosystems. Any coastal pH decrease has a major impact on animals such as corals, oysters and mussels, whose shells and skeletons can become more brittle in low-pH environments.
- This is a major concern for shellfish fisheries, which contribute over $1 billion annually to the U.S. economy while providing more than 100,000 jobs.
- Efforts to conserve marine plants and seaweeds in shoreline habitats, including where commercial seafood is harvested.
- The environmental and economic consequences resulting from ocean acidification are dire
- “Decreasing CO2 emissions is still the No. 1 most important way to protect our marine ecosystems, but our research indicates that marine life also has substantial control over coastal pH.”
