Unfortunately, at the same time as we're discovering this treasure troveof potentially habitable worlds,our own planet is sagging under the weight of humanity.2014 was the hottest year on record.Glaciers and sea ice that have been with us for millenniaare now disappearing in a matter of decades.These planetary-scale environmental changes that we have set in motionare rapidly outpacing our ability to alter their course.

But I'm not a climate scientist, I'm an astronomer.I study planetary habitability as influenced by starswith the hopes of finding the places in the universewhere we might discover life beyond our own planet.You could say that I look for choice alien real estate.

But the goals of interplanetary exploration and planetary preservationare not opposed to one another.No, they're in fact two sides of the same goal:to understand, preserve and improve life into the future.The extreme environments of our own world are alien vistas.They're just closer to home.If we can understand how to create and maintain habitable spacesout of hostile, inhospitable spaces here on Earth,perhaps we can meet the needs of both preserving our own environmentand moving beyond it.

If we truly believe in our abilityto bend the hostile environments of Mars for human habitation,then we should be able to surmount the far easier task of preservingthe habitability of the Earth.
