The ecosystem has a good regulation on its own to maintain a balance. With increasing Human activity, the PH value in rivers and bays have become acidity that affecting creatures like oysters and crabs. How does the PH value affected?
Seagrasses and other underwater plants helps smooth the surrounding water, providing a favorable environment for other marine lives like fish and crab. They also consolidate solid underwater to provide a safer place for marine animals even in the wind or waves.
However, when more people are living near the bay, the grasses are greatly affected. Human activity has released nitrogen-rich pollutants into the water, causing the death of grasses and other underwater plants.
Enormous amount of nutrient accumulated in the water lead to algal blooms at the water’s surface. As the algae die and sink to the bottom, bacteria consume them with consuming oxygen and releasing carbon-rich wast. Without enough oxygen and waste, nothing can grow under the water. Worse still, a strong wind can bring those super-acidic water back to the surface and harming creatures like oysters and crabs as the acidity damage their shells made of calcium carbonate.
Scientists find that seagrass and other vegetation are effective in getting the Ph value of water back to normal though the rationale remains unknown. It is clear that the grasses spread their little acid-neutralizing crystals far and facilitate the shell-growers downstream. Experts said the finding will promote restoring more seagrasses in the bay.
