This enormous pumpkin will devour us all!!!
By the by, what do they even do with those giant pumpkins? If they're grown just for size and they're no long edible it seems like a gigantic waste.
Call it a waste of that grower's time, but they're mostly just water. What's wasted? Fertilizer is all I can think of, and it takes very little.
Water I guess, but in the age of data centers, that doesn't really seem to matter anymore.
Depends. We have zero water issues in NW Florida, while we are draining the Colorado River and Western aquifers dry.
It's still a literal ton of vegetal mass, you can compost it. Competition for the sake of competition is wasteful in general, look at the Olympics.
The competition part isn't that wasteful in the Olympics. It's the surrounding corruption.
It's still done for its own sake, any resources put into it can generally be considered wasted if the Olympics themselves aren't part of the value equation.
They turn them into boats and race each other

Well okay now that looks hella fun.
Most hobbies are wasteful? Who cares? Let people have fun. At least the pumpkin and all the nutrients in it can be tilled back into the soil it came from.
Maybe pumpkins are like goldfish and grow to fill their environment. Grow one in the center of a field all by itself. See if it takes up the whole field.
