Low tech solutions are sometimes the best thing one can do to save the planet. For instance, a new carbon sequestration method arises through a newly published paper. The research says that this method can cut CO2 emissions by 15% per year. How is this done? Simply enough a 5th grader could understand.
Plants absorb CO2 and release oxygen. The absorbed CO2 goes straight into the plant’s body, where it forms more complex organic material. The study suggests taking the crop waste after the harvest and dump it into the ocean, thus sinking the CO2.
The deep ocean water does not mix with waters and currents closer to the surface, phenomena that could secure the crop waste at high depths. The study also suggests that if the waste is dumped near “alluvial fans” (places off the edge of the continental shelf where rivers meet the ocean), then the waste would be buried by silt from those rivers. Cold water would prevent the waste’s devay.
If 30% of the world’s waste crop is sunk annually into the ocean, it could remove about 600 megatons of carbon, counting to about 15% of the CO2 in the atmosphere. This process’ efficiency is of about 92%, compared with another carbon sequestration methods.
Ok, we could do this, but what would be the impact on marine life after that? What could be the types of organisms that would consume those crops, and would they do any good or bad to them? Anyway, it’s just an idea, good in case everything goes wrong and we have nothing else to do anymore.
