text: The first idea the author had was related to the atmosphere of Venus. "A thick atmosphere of almost 97 percent carbon dioxide blankets Venus. Even more challenging are the coulds of higly corrosive sufuric acid in Venus's atmosphere." In Paragraph 3, the author does not give a higly convincing argument. Humans need oxygen to live, so how is it expected for them to survive on a planet that has little to no oxygen? It is not possible to change the chemical makeup of an entire planet. The argument displayed by the author is not credible in any way and does not give any reason as to why one would want to continure research in this area.
