The planet Venus is an interesting place, but not somewhere you would want to go anytime soon. Because the atmosphere is mainly carbon dioxide it has a run-away greenhouse which means the temperatures at the surface would melt lead and the pressures are similarly unhealthy.
However if you’d like to think what it could be like in a few thousand years, just think about the film Avotar.
Venus has been described as Earth’s twin and so could represent a great deal of real estate for those clever and brave enough to try and change it.
Its atmosphere has too much of some things and not enough of others, so the first thing that would need to be done would be to alter its composition by bringing mountains of ice, phosphorus and other things from other parts of our solar system.
Then we would need to convert carbon dioxide into carbon and oxygen, and remove quantities of both. On earth you could do this by planting millions of trees. But trees would be vaporised on the surface of Venus.
Therefore they would have to be planted at the top of the atmosphere. This could be done using the sort of organisms that did it in earth’s early history such as stromatolites. But they would have to breathe in CO2 and breathe out Oxygen into an internal space. This would make them blow up like balloons, but would make them float above the atmosphere rather than sinking down and being incinerated.
Again it’s just science fiction but we are not too far away from being able to manipulate DNA and grow completely new types of organisms rather than just moving bits of DNA between one plant and another.
