Oysters are bivalve mollusks with a distinctive elongated shape. They are a nutritious seafood that many people love. What will happen to the environment if the number of oysters decreases? How can we help Pacific oysters develop sustainably? Let’s follow the article below by BAVABI to clarify this issue.
Effects of oysters: Fighting the climate crisis
Using oysters as food is not only good for health, but it is also a way to protect this world. Contribute to making the world greener and cleaner. Commercial farming of Pacific milk oysters does not require fertilizers, food and fresh water. Oysters eat natural phytoplankton, which contributes significantly to improving the environment.
Being filter feeders, oysters can clean up our polluted ocean waters by filtering out toxins. In particular, oyster reefs also help reduce erosion caused by storms and high tides.
Decomposing in water, oyster shells add calcium to the water, helping to combat ocean acidification. The main cause is carbon dioxide emissions.
Specifically, when there is a dangerous algal bloom, oysters will try to suck and filter water until the excess algae is removed. Without oysters, algae can take up all the oxygen in the water column. This creates a dead zone where no living things can survive. Therefore, the effect of oysters on the marine ecosystem is extremely important.
Threats to oysters
Currently, the number of oysters in nature is no longer large. The small number of oysters in nature is no longer enough to perform their function in the marine environment.
Technically, oysters are considered extinct. There are many reasons for the decline in the number of species.
- It may be due to human waste treatment that causes severe pollution of water quality and the environment.
- Due to oysters being infected with toxic viruses, pandemics, predators, climate change…
In addition, there are many other reasons leading to the scarcity of natural oysters. This is also a warning for the marine environment. Because the effect of oysters on the clean ecosystem is no longer met.
The return of oyster farmers
Faced with the decline of oysters, many oyster farming alliances have been established. This was followed by a partnership with the World Wildlife Fund (WWF), which aims to bring together oyster farmers across the country to drive climate policy.
Membership has grown rapidly. Chefs and seafood distributors are also joining these organizations.
This is a necessary and urgent partnership to save our oceans and our planet. This issue needs to be spread globally. With more policies, more advocacy, more conservation projects. Contribute to protecting oyster species and enhancing the environmental impact of oysters.
