求翻译:Sagan suggests that algae (藻类), plant life that can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be produced in conditions similar to those on Venus. The algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the gasses in the atmosphere and change them into oxygen that people can breathe. But before man can set foot on Venus, it will be necessary for the oxygen to produce rain to cool the planet, so that after a few years conditions like those on Earth will be produced.是什么意思? 待解决
