SPOILERS - my plants died so....

how could that happen??

I don't understand how such a stupid design for the greenhouse module was made. You are on another planet, no livable atmosphere and you build a greenhouse with NO AIRLOCKS?!!? Well, actually first you build a green house with a door to the OUTSIDE... why? what are you going to bring stuff in and out the greenhouse from the OUTSIDE?

door connections BETWEEN the modules have pressure doors, i understand, but this door lead OUTSIDE!! this is unbelievably STUPID

p.s. the doctor knew something was up with dude as well as his wife...well before the "accident"

p.p.s. how can you watch a monitor with this dude standing SHIRTLESS in a reduced heat environment in front of an exit door (see above) and not IMMEDIATELY react??
