I think I remember reading somewhere that we are about 10-20 years away from terraform technology that will allow us to redesign a planet enough to be suitable for us to live on, such as Mars.
[font=Verdana][color=green]Indeed. However, it takes many hundreds of years in terraform a planet. Venus will take even longer than Mars to terraform. The likely hood of our race trying to terraform a planet when the technology is developed is highly unlikely to start straight away though. We'll likely be very old by the time anything happens.
However, despite scientists trying to stop the inevitable, our races existence is guaranteed to end a lot sooner than we may think. Not 2012 before you all scoff, but our planet will be devoured by a blackhole before the Sun dies/expands to a Red Giant and incinerates our planet.
