For reference, carbon dioxide hasn't been this high in the atmosphere at any time during Homo sapiens tenure on this planet.

|Thirteen months' growth of a white teak tree in the desert of Ecuador - truly incredible growth without watering and with the Waterboxx|
|Three years' growth of a salt cedar (invasive in the U.S.) tree with the Groasis Waterboxx in the Sahara Desert! These trees had over 88% survival with no watering after planting when the Waterboxx was used. |
