1Seagrass meadows（海草草甸）are wonder plants growing beneath the sea.They feed and shelter sea life and are masterful at storing carbon.Thanks to the assistance of tiger sharks, a huge seagrass meadow in the Bahamas Banks was recently discovered, offering the world a tool to fight climate change.

2Seagrass has usually been detected by Earth-orbiting satellites that identify darker patches in the blue water.In this study, tiger sharks were selected as research tools due to their highly consistent associations with seagrass ecosystems.They spend 72% of their time in seagrass meadows.The team equipped eight tiger sharks with satellite tags,seven sharks with camera tags,and used a 360-degree camera on a shark for the first time ever.

3The data researchers collected was astonishing.The world's largest seagrass ecosystem,measuring at least 66,900 square kilometers,has been discovered.This reflects a 41%increase from the previous estimate of global seagrass.Seagrass can capture（捕獲）huge quantities of carbon by photosynthesis (光合作用) and store it on the seafloor.In terms of climate change, this is excellent news.Seagrass is 35 times faster at removing carbon than tropical rainforests.When referred to global seagrass carbon stock estimates, the study indicates that seagrass in the Bahamas may contain 19.2% to 26.3% of all the carbon stored in seagrass meadows on Earth.

4Yet seagrass meadows are rapidly disappearing,with over 92%of meadows in the UK gone, according to the World Wildlife Fund.Scientists are collecting seeds and trying to grow new seagrass meadows through restoration projects.This new discovery offers optimism and proves the importance of the ocean for healing.

5The sharks led us to the seagrass ecosystem in the Bahamas, which we now know is likely the most significant blue carbon sink on the planet.What this discovery shows us is that ocean exploration and research are essential for a healthy future.The untapped potential of the ocean is limitless.These meadows can be protected and can be copied, offering hope for fighting climate change around the globe.
