How can something so small take up so much space?

So even though our boy is still a while from being, he now takes up about as much space as I do. It's amazing how much stuff is useful (note, not required as pretty all we really need is food and shelter) that we have bought. It takes a village's worth of stuff to raise a kid nowadays apparently.

So we now have all the stuff we really need while leaving some things for the baby shower. We have a crib, changing table, stroller, car seat, a whole mess of clothes, and probably a million other things that I'm forgetting. So now we've been clearing out boxes and breaking them down and throwing out volumes of styrofoam. It's nuts, and we're not even close to being done as there are plenty of things we will need to get once the kid arrives.

So does anyone else find it ironic that supposedly green companies pack their stuff in styrofoam and multiple boxes? Seems kind of wasteful to me.
