Fish Help Slow Global Warming With Gut Rocks
Scientists believe fish excrete lumps of calcium carbonate, known as “gut rocks,” that help maintain the ocean’s pH level.
By drinking salt water, fish ingest a lot of calcium, and they excrete more or less calcium carbonate depending on their size and the temperature of the water. “For a given total mass of fish, smaller fish produce more than bigger fish, and fish at higher temperatures produce more than fish at lower temperatures,” explains Rod Wilson of the University of Exeter in the UK.
The interaction between humans, animals and climage change is becoming more evident.
