So if mankind plans to 'teraform' another planet - namely Mars, then why doesn't it address a rather obvious problem? Radiation

Teraforming suggests making a planet habitable for humans, by eventually generating atmosphere, and air to breath by using plant life. But it doesn't account for the obvious problem of radiation. How would teraforming work on Mars if it is geologically dead?

No hot core so there is no magnetic field to protect against lethal solar winds, which would most likely kill off the plants in the first place.

What does /sci/ think of teraforming anyways?

I've heard that it could take 500 years to make mars a hospitable planet, but are there ways we could do it faster? like in the area of 100 years or possibly less? We will be using future technology and some tools may not be known to us yet. how could it be done?
