气态星球上可能存在巨型浮游生物。它们像小型飞船那样漂在厚厚的大气中,靠“吃”闪电获取能量为生。
There may be giant plankton on gaseous planets. They float in a thick atmosphere like small spaceships and live by "eating" lightning.
向海洋中倾倒铁以促进浮游生物生长来吸收大气中的二氧化碳。
Dump iron into the sea to boost plankton growth and soak up carbon dioxide from the atmosphere.
这一方案受到了众多的关注,尽管在这种浮游生物死亡后,它所吸收的二氧化碳会重新释放到大气中,但大约有8-9%的二氧化碳能被保留在海洋深处长达十年甚至更长的时间。
Though much of the carbon thus absorbed returns to the atmosphere when the plankton die, around 8-9% ends up locked away beneath the waves for decades or more.
