I was a bit discouraged to hear that the CO2 the plants remove is ultimately rereleased into the atmosphere when the plant decomposes. So I’m wondering what positive impacts I’m making with my backyard garden, if any.
Also, with millions of gardens, would they really be totally useless for CO2 removal? Or is there some small amount that gets captured by the plant and then *not* rereleased into the atmosphere, in other words, permanently removed from the air?

Think of it this way. The amount of CO2 the plant removes from the atmosphere gets put back eventually. But that CO2 is removed for a bit. And in that bit it’s a (very) little cleaner.
But don’t think about the garden itself. Think of the CO2 of the massive farm. People driving to work at the farm. Farm equipment. The farm it took to produce the seeds for planting. The CO2 at the factory that made the farm equipment. The CO2 made to transport the farm equipment. Etc.
A small garden isn’t going to remove waste CO2 from something as large as this planet. Just isn’t happening. And anyone telling you that is probably selling garden stuff.
