While reading an article about a possible "Cloud City" on Venus I was taken by the following statement:
Venus’s atmosphere is mainly carbon dioxide and thick clouds of sulfuric acid cover the entire planet. “The atmosphere traps the small amount of energy from the sun that reaches the surface along with the heat the planet itself releases,” NASA explains. “This greenhouse effect has made the surface and lower atmosphere of Venus one of the hottest places in the solar system.”
If Venus's atmosphere is 'mainly' carbon dioxide and plants process CO2 into O2 what would happen if we just dumped an enormous amount of plant life onto Venus? (of course aiming to no land in a lava plain... say on top of a mountain). Would the plants be able to begin the process of creating an sustainable oxygen rich atmosphere?
