For example, "At thirty-plus miles above the surface, temperatures would still be toasty at around 170 degrees Fahrenheit, but the air pressure would be close to that of sea level on Earth. Solar power would be plentiful, and radiation would not exceed Earth levels. Not easy conditions, but survivable for humans." This shows that the author wanted the reader to know that living on Venus is not far fetched.
