Greenhouses

Why does this greenhouse flourish?
Why is it so lush and prosperous?
Did these plants just spout from the ground and tend to themselves?
Or were these plants taken from somewhere else and nurtured as though the owner created them himself?
Why are these conditions best for these plants?
Why is this greenhouse barren?
Is this ground less fertile, less developed or less desirable?
Did someone steal the plants and bins (wealth) that this greenhouse once held?
Maybe it's now the environment's fault if only weeds grow when all other resources were removed?
Why aren't these conditions best for growing a desirable crop of plants?
