That's very shallow dismissal. Yes, it's true "just planting a lot of plants" will lead to disappointment. But it's the same as with "just build lots of solar panels/windmills" without any systematic thinking. Natural and sustainably managed biomes don't require irrigation. I know, there are deserts where much biomass won't ever naturally grow, but no solution is suitable everywhere. Trees can and do last longer than 100 years, and even after death they don't puff release co2 immediately. When left undisturbed, large part of carbon is left fixed in the soil.
