Why is the atmosphere of Venus more friendly to plant than humans?
Question Date: 2016-02-22
Answer 1:

First let's look at the composition of the atmosphere of Venus. Venus has an atmosphere that is way over 90% CO2 (Carbon Dioxide). That means that no human would survive because we need to breathe oxygen.

Plants can grow in high CO2 conditions because they use CO2 for photosynthesis -- in fact sometimes we pump CO2 into greenhouses to help they grow more. This would make plants slightly better off on Venus. But I want to emphasize that although their CO2 tolerance would make plants better candidates than humans, there are other factors (like very high temperature) that would not make them good candidates to survive on Venus.
