Fish help prevent warming of the Earth

Scientists at Columbia University in Canada have discovered an unprecedented role for fish, a "buffer layer" against climate change.
Fish is a "buffer layer" against climate change.
Nearly 50% of carbon dioxide - the main "culprit" of warming Earth - that people have emitted into the atmosphere over the past 200 years has been absorbed by the sea, causing the ocean to become acidified, causing many Sea creatures are hard to create limestone crust.
According to scientists, fish exchange gas by sucking oxygen-rich water through their mouths. This process also puts a lot of calcium in their abdomen.
However, in order not to form calcium stones in the body, fish eliminate this calcium through "calcium pill".
It is the calcium tablets produced by excreted fish that increase the pH of the ocean and reduce the concentration of acid.
According to US, British and Canadian scientists, the total weight of fish species living on Earth is about 2 billion tons.
On average, people catch about 100 million tons of fish each year, equivalent to 5% of the total fish stock on Earth. This is a small percentage because about half of the world's fish species live in deep waters that humans cannot catch.
