You see the pedals are made so they screw in with the same rotation as the pedal spins (on forward motion of course). So as you press the pedal the pedal, even if not screwed in correctly, it ...

Pedals falling off is at best inconvenient, at worst can lead to crash and serious injury. Easiest option is to replace the cranks. Its not a big job but parts cost might mean a repair is a better option for you. The bottom bracket will ...
The only thing you can do that is safe and reliable and sane is to get a new crankset.
