no round

I wonder what everything would be like if there were no round or circular objects on earth. What everything look like would be a mystery to me. In fact, if you have ever played minecraft, this is what the world would generally look like. Actually, it wouldn't quite look like that because round things would just be composed of many many tiny block pixels. It really wouldn't be much different than now because you would be able to make round things out of non-rounded blocks. Things might be a little bit rough but things would still be about the same. It is a weird thing to imagine but in reality, I don't think anything now is actually circular either, because technically, circles can be composed of many straight lines.
