That sounds like an organizational problem, not a problem with Lego bricks.

You can never have enough Lego. :)

It's not an organizational problem... it's a swoooosh-playing-with-my-lego-thing-oops-a-piece-shattered-off-and-I-can't-find-it problem.

And then later, the lego piece waits for nightfall, and crawls out from the dark nook to the middle of the most inconvenient walkway for its moment to strike.

That is why I always assemble my LEGO in a pressurised cleanroom.

All this time I thought that it was house hippos playing with the ones I dropped.

I have stepped on 1 LEGO brick in my life, and it truly is enough for my lifetime.

Thanks to LEGO I learned that the callus on your ankle is layered like an onion.

I had far too many LEGOs as a kid, and left them around my room like a minefield. Did I step on one? Oh, no. I was jumping on my bed and jumped off when told to stop by my parents and unfortunately one ankle landed on the corner of a LEGO building I had made. A structure build like a little plastic brick shithouse, apparently. The corner gouged a nice right angle cleft out of my ankle a couple inches long. Hurt like the dickens!

I first stepped on my own LEGO bricks (usually blue bricks that were part of some space station). Now, I equally proudly step on the bricks owned by my offspring. It's wonderful that some fascination transcends generations.

As of July 2015, 600 billion Lego parts had been produced.[1]

That's quite a few pieces for every man, woman, and child on the planet.

I wonder how many cubic kilometers of plastic that is

Significantly less than one; probably just roughly a cubic hectometer at most. A cubic kilometer corresponds to about 1.6 x 10^15 1x1 Lego blocks, so over a quadrillion. 600 billion is only 0.6 x 10^12.

400 Lego 2x4s makes a kilogram. So let’s say a cool billion kilograms.

And since Lego essentially never is thrown away (except by spite or accident), that's more or less 1 megaton of carbon capture right there.

I don't think you get to count plastic you produce from extracted sources as carbon capture.

As long as you don't burn it, it's pre-emptive CCS. At least that's what I tell the investors.

if they are made large enough, one may reside whithin, and eliminate the discomfort of treading upon them.

Fakirs will love it.
