These plants are the primary architects of “blue carbon” sinks, coastal ecosystems that can sequester carbon at rates up to three times higher than terrestrial forests.

I don’t think plants of any type should be called carbon sinks. It gives people the false idea that trees are some kind of solution to carbon released by burning fossil fuels. That carbon is just going to go back into the atmosphere when the tree dies and decays.

If it’s not shoving the carbon back underground for hundreds of thousands of years, it’s, at best, a carbon bucket on a wobbly table.
