Loads of pumpkins for sale in supermarkets.
I don't want to come across as a miserable piece of shit but I think it's an incredible waste. All these pumpkins are grown to make lanterns with, and the flesh is thrown away (not that it would be worth eating as apparently Halloween pumpkins are vile). I bet the vast majority of people would just throw the flesh away anyway, even if it did taste nice.
Just seems mad to have all the resources dedicated to grow and distribute pumpkins in this day and age where people are skint and hungry and have to use food banks. Just to make lanterns for one day.
