The Ecosphere Restoration Institute received $5 million from the Florida State Legislature to restore the declining seagrasses on 100 acres of the coast. The organization partnered with experts who have permits to harvest the seeds, grow them in a nursery, and replant them in shallow areas. The project will also help prevent manatee deaths, as the animal depends on seagrass as a food source.

The SeaStore Seagrass Restoration Project in Kiel, Germany, is teaching locals to harvest and replant the underwater grasses. The project is restoring areas these plants used to inhabit because they store large amounts of carbon.

A project at the Volgenau Virginia Coast Reserve has restored 10,000 acres of seagrass meadow. For two decades, scientists and volunteers have worked together to collect, process, and plant seeds to grow the carbon-storing underwater plants.

A Spanish chef piloted a project to start a “marine garden” — cultivating eelgrass and obtaining grains it produces to be used in different recipes. The grain has healthy benefits, including 50 percent more protein than rice, and growing the seagrass can transform salt marshes into biodiverse ecosystems that can also capture carbon emissions. They are working to scale the project to understand the ideal conditions to grow the plants.

Vaan Island, off the coast of Indian in the Gulf of Mannar, is rapidly sinking. But scientists are working to prevent that erosion by replanting seagrass, which is an important plant in a marine ecosystem. Despite fishermen pulling up the seagrass with their nets, so far, nine acres of seagrass have been rehabilitated in the area.

Belize, cited by Darwin as home to “the most remarkable reef in the West Indies," recently became the first country to issue a moratorium on all offshore oil exploration and drilling in order to protect the reef and the species that rely on it.

Running Tide Technologies, a shellfish hatchery in Maine, is betting on kelp forests as a way to store carbon deep in the ocean and sell that carbon to corporations looking to combat climate change and offset their own emissions. The startup is growing mini-farms of kelp on biodegradable floats and after a few months, they sink to the seafloor. More research is needed to see if it works, but they already have about 1,600 floats adrift in the ocean and the e-commerce company Shopify is the first to buy carbon offsets from them.
