Since at least the late Mesozoic, the abundance of terrestrial vegetation has been the major factor in atmospheric carbon dioxideloxygen fluctuations. Of modern ecosystem types occupying more than 1 percent of the earth's surface, productivity/area ratios of terrestrial ecosystems (excepting tundra and alpine meadow, desert scrub, and rock, ice, and sand) exceed those of marine ecosystems and probably have done so for much of late Phanerozoic time. Reduction of terrestrial ecosystems during marine transgression would decrease the world primary productivity, thus increasing the atmospheric carbon dioxide concentration and decreasing the oxygen concentration. Regression would produce opposite effects.
自至少晚中生代以来，陆地植被的丰度一直是大气二氧化碳-氧气波动的主要因素。在占据地球表面 1%以上的现代生态系统类型中，陆地生态系统（除了冻原和高山草甸、沙漠灌丛以及岩石、冰和沙）的生产力/面积比超过了海洋生态系统，而且在晚显生宙的大部分时间里可能一直如此。海洋进积期间陆地生态系统的减少将降低世界初级生产力，从而增加大气二氧化碳浓度并降低氧气浓度。海退则会产生相反的影响。
