For instance, if the earth were slightly larger, hydrogen, a light gas, could not escape into the atmosphere at its prescribed rate (due to an increase in the earth's gravitational field), and over time would build up and cause life to cease.

On the other hand, of the earth were slightly larger, gravity would be stronger and then the light gas of hydrogen (much lighter than air) would not disperse into space at its now prescribed rate, eventually resulting in the earth being unable to sustain life.

If the earth were slightly larger, having a stronger gravitational force, it would prevent hydrogen, a light gas, from escaping at a specified rate, building up in our atmosphere and eventually rendering our planet lifeless.
