Is Terraforming Mars A Bad Idea?

Of all the worlds ever graced by science fiction, Mars is second to only Earth in honorable mentions. Previously imagined in the past to harbor advanced civilizations, many space enthusiasts today now seek to not only visit Mars, but to transform this rusty world into a second Earth.

Although having a second home world (if not more) in our solar system is probably a wise idea, terraforming Mars into a miniature Earth could present new challenges making it very difficult into calling the red planet home.

Despite their similarities, Martian weather seems to be much more violent than its larger terrestrial brother Earth. Having less than 1% of the air pressure of Earth, Martian gusts seem to be able to generate wind speeds of up to 375 miles per hour.

Although Earth is no stranger when it comes to fierce storms, our planet has yet to encounter one on a global scale, an experience Mars seems to be very familiar with. If our species were ever to raise the air pressure to Earth levels, future colonists may end up finding themselves trapped on a world whose weather would put category five hurricanes to shame.

If raising the air pressure on Mars was not bad, raising the temperatures may be worse. Lacking major oceans, future colonists would be able to establish outposts throughout the red planet’s surface, which area wise is roughly equal (in size) to all of the dry land on planet Earth.

With a large portion of water potentially lying beneath half of the Martian soil, (hat tip: Posthuman blues) as well as the polar ice caps, raising current temperatures on our future home world could end up flooding the planet. Although Martian oceans would definitely compliment this barren world (at least from space), they may provide little “land room” for colonists desiring to set up shop on Earth’s distant neighbor.

Last but not least, a terraformed Mars may not be as “wildlife friendly” as planet Earth, enabling only humans and certain pets to dwell upon the surface. Unlike Earth, Mars lacks a global magnetic field which many animals such as birds, bats and certain insects depend upon for migration and navigation.

Although humans could easily navigate via an artificial GPS system, our animal friends may not be as fortunate. Unless an artificial magnetic field could be constructed, humanity will be unable to create the large ecosystems necessary to recreate the red desert into a thriving oasis.

Despite being a far cry from Earth like conditions, Mars may prove to be more livable in its current state than as a terraformed world. Humanities understanding of weather (especially global warming) is still in its infancy, and if we are not careful, our attempts at turning a world into an oasis may end up turning the world against ourselves.
