Every species, given the opportunity, expands its numbers to the carrying capacity of its environment. Humans are simply much better at it, as "our environment" and therefore its carrying capacity is a function of both our technology and our biology.

Concerns about resource availability are absurd when one considers what's available in the solar system alone. I doubt that the bulk of the species will live off-world any time soon, but industrialization of space doesn't require that. Environmentalists like to say that for everyone to enjoy a first world standard of living we'd need 4 Earths. With the solar system at our fingertips we have the equivalent of far more than 4.

To make life worth living on Mars, we'd need to import an ocean and atmosphere. Given that Mars has no magnetic field to speak of, we'd probably need an atmosphere thicker than Earth's to provide adequate shielding from cosmic rays.

The question is: do you want people living on the surface before you start dropping ice balls from above? Could be dangerous.
