That’s not what that article says. At all.

As mentioned in the article, moss is pretty good at pulling particulates out of the air and “cleaning” it in that sense.

But trying to get CO2 out of the air isn’t the same. Trees are very effective at this because they have a lot of mass and density are largely carbon themselves. When we talk about “carbon sequestering”, we’re generally talking things like trees because that carbon from the air has to go somewhere and having a huge dense chunk of carbon is basically the most efficient natural method.

Moss is good at removing other particles, but trees are generally still better at carbon sequestering and CO2 removal.
