Without a functional protective magnetic field around itself, a terrestrial planet such as Mars would be extremely vulnerable to harsh solar winds and lose all the water on its surface, making it incapable of sustaining life.

Why does solar wind strip water from the planet? For some reason I thought Mars' smaller size and less gravity was more the reason for it's state.

Water doesn't exist in liquid form in low-pressure environments. If the atmosphere gets stripped off, so will all non-ice water.
