a small fish reducing climate change

Anchovy indeed small. However, studies have shown that fish contribute to combat climate change. Fese anchovy help store carbon.


Grace Saba from Rutgers University in New Jersey and Deborah Steinberg of the Virginia Institute of Marine Science, based on the study said, anchovies eat algae. Digestive Stool mendendap rest quickly in the ocean and bring carbon.

"Faecal pellets from the surface can move settles down with a speed of up to 1600 feet (487 meters) in less than a day for study," said Saba.

Based on the study, as reported by Discovery, Friday (12/10/2012), each stool storing carbon to 22 micrograms.

"Twenty micrograms may not look much. But if you multiply it by the number of fish and feces that may exist in the nutrient-rich areas, the numbers will be quite large," said Steinberg.

And indeed, as much as 251 milligrams per square meter settles feces every day.

"Our findings suggest that under certain conditions, fish feces can send material from the surface to the depths, and do it quickly," said Saba.

Anchovies are not the only species of fish that help fight climate change. In the spectrum of different size, sperm whales do.

Dirt whales feed on the surface of micro flora, phytoplankton. Dead phytoplankton will sink to the bottom of the ocean brings with carbon dioxide absorbed. The amount of carbon absorbed diokdida through this process could reach 2 million tons per year.

Known, the concentration of carbon dioxide increases in the atmosphere affects climate change. With the abundance of carbon dioxide is absorbed, climate change can be combated.
