Adding onto the other comments (durable for generations) - almost no other toy is like that. Barbies break. Toy cars break or the models get out of fashion. Electronic stuff is broken or severely out of date 20 years later. Sport equipment can be durable, but usually holds for less than 10 years. In the grand scheme of things, Lego is completely fine, we have hundreds of more wasteful one-time-plastic usages.
