It is a question I ask myself. Some guesses: - People have more Lego. Passed over collections become bigger and bigger. Maybe the average collection was 2 boxes of bricks before, now it is 5. - More people use Lego. There is a lot of Lego for adults now. It is not just for kids, but kids still play with Lego. People, especially adults can make bigger models too, with more bricks. - A lot of Lego are stored in attics, unused. What will happen to them after they are rediscovered? I don't know, but they will probably end up growing someone else's collection. - Some may end up in landfills, lost, broken, etc... But I think it is a very small amount. Used, bulk Lego bricks are about $15/kg, more than copper scrap, it would be worth digging for them if they were a common occurrence.
