HOW OYSTERS ARE FIGHTING CLIMATE CHANGE

These oyster farms are also playing a crucial role in the battle against global warming, according to experts.

One of the key advantages of oyster farming is that farmers do not have to produce the food to get the oysters to grow. Oysters eat phytoplankton or small bits of algae suspended in the water.

Oysters also do not produce methane, unlike cattle and sheep.

Their shells, which are composed of calcium carbonate, act as natural carbon cleansers.

“That calcium carbonate is actually removing carbon from the carbon cycle,” said Ms Beaumont. 

“So as we grow these oysters, so long as we do not put their shells back in the river and put them on land or somewhere safe, you are going to find that you are actually removing carbon from that carbon cycle. By doing so, you are reducing those greenhouse gases and you are then going to reduce the effects of climate change.”
