“Only fools find joy in the prospect of climate engineering.” — Ken Caldeira
“Healthy, natural ecosystems are carbon sinks that draw carbon dioxide from the atmosphere and sequester it in sediments, peat and carbonate rock. It has been estimated that every year healthy saltmarshes, mangroves and seagrass beds collectively remove carbon dioxide equivalent to half the emissions of the world’s transport network (which totalled about 13.5 per cent of global emissions in 2000). Despite covering only 1/200th of the area of the world’s terrestrial vegetation, these habitats remove a comparable amount of carbon from the atmosphere. This makes them some of the most intensive carbon sinks on the planet.
And yet, just when we need them most, these habitats are being lost at an alarming rate of 2-7 per cent a year. If we were to halt our losses today, we might have the same impact as the 10 per cent reduction in emissions that would be required to stabilize warming at 2 degrees Celsius or less. If we embarked upon large-scale habitat restoration efforts, like those undertaken for Vietnam’s majestic mangrove swamps following the widespread use of defoliants during the war, they could contribute more. So if you can do just one thing, protect the saltmarshes and mangrove swamps!” — Callum Roberts, Ocean of Life: How our Seas are Changing
