Is it the worst invention? Looking at the environmental concerns, it uses up landfill space but that isn't a huge concern. Worst invention would be Oxycotin since the number of lives it has destroyed. Or maybe the V6 or larger engines for the amount of pollution these engines have generated over smaller engines. Or microbead plastics.
