While I agree that natural forests are unlikely to make a significant dent in CO2 through biological photosynthesis, that is not necessarily true for all plants

While I agree that natural forests are unlikely to make a significant dent in CO2 through biological photosynthesis, that is not necessarily true for all plants. Kelp and Bamboo farming can do quite a lot more than the average tree with their extremely high growth rates. Just need to figure out what to do with the resulting product.
