@angst_ridden @thomasfuchs tbh that could be deployed in areas where for example due to a lack of water afforestation is not possible

after all, photosynthesis, with a net equation of n H2O+n CO2->(CH2O)n+n O2, consumes a tonne and a third of water for each tonne of carbon fixed, plus more that is lost through evapotranspiration
