Mag, trees are plants too, you know.
Anyway, the short lifespan of hemp is what gives it such a big advantage. Compare 50 years of hemp growing vs 50 years of trees. Hemp far outperforms it in terms of carbon fixation |
But hemp plants die several times in that lifespan (winter times, seasonal changes), they dont intake as much greenhouse gases, and other factors that I listed - and when the plants lifespan ends, its all released back into the air or smoked up by humans (and released into the air). The purpose of marijuana plants is not to stabilize CO2 and such but to provide satisfaction and enjoyment to humans and to grow medicines/food/oils/paper/fibres from hemp (great benefit, can save trees). I know well about hemp and its benefits. Using hemp will save trees and hemp paper/fibres are actually better than paper products made from trees, as one example. I support using hemp instead of trees, thus the trees can do all the carbon fixation and cleaning our air, while hemp can feed us, clothe us and make some other happy and high. Using both of them is important, using just hemp and continuing destruction of trees - not such a good idea.
Mature trees are second best to only plankton/algae in terms of stabilizing carbon and intaking all those substances mentioned. But it figures - look at how much of Earth's area is covered by water - if it was inversed with 70% land and only 30% water, then trees would obviously have a clear upper effect. Trees also only represent a portion of that 30% of land (a lot of land is also covered by mountains, deserts, taiga/ice/snow).
Also, when trees are cut down, oceans dont absorb carbon dioxide at higher rates, still the same rates. And when trees are not planted back (and it takes a long time for mature trees to grow back to their optimal levels where they can have their effect), there's an excess CO2 in the cycle that results in these Al Gore readings of global warming. More humans = more demand for arable land = more demand for cattle ranch grounds farms = more trees cut down. As long as our population continues to grow, and as long as we keep continually ignoring the devastating issue of deforestation, expect CO2 levels to icrease, air quality and climate to deteriorate from lack of trees that stabilize it, and many more species disappear and soil degregade. Can anyone here sponsor a new movie Inconvenient Nature?
