Therefore reduction means a receiving or gaining of electrons (decrease in its oxidation state),4 such as when an antioxidant donates an electron to a free radical. The free radical is reduced and the antioxidant is oxidized. The antioxidant is said to be the âreducing agentâ; it reduced the free radical.
First, alternatives to terraforming. It would be possible to live on Venus in the high atmosphere, in giant floating cities. Using a standard space-station atmospheric mix at about half an earth atmosphere, a pressurized geodesic sphere would float naturally somewhere above the bulk of the clouds of sulfuric acid.t would be possible to live on Venus in the high atmosphere, in giant floating cities.

Take Venus. Despite being Earthlike in size and composition, Venus has a surface of crushing pressure and 900-degree temperatures, making it almost certain that no life could survive â on the surface. But the surface isnât the only environment on the planet where life could conceivably exist.enus does have active volcanoes, but not as many as Earth (since it has no plate tectonics), and itâs not certain whether itâs enough to account for the measured abundances. Itâs possible that some as-yet-unknown chemical pathway is breaking down carbon monoxide and producing these other compounds.
