As far as entertainment goes, carving a pumpkin and then letting it quickly compost away is relatively low impact.
You could always argue that the most environmentally friendly option is to do nothing at all and cause nothing to be produced or moved around, but that's hardly a realistic argument. Criticizing every activity that causes something to be consumed, no matter how renewable or compostable, is hardly productive.
Once the environmental arguments get to the point where we're criticizing people for carving a vegetable up but not eating it once per year, it gets hard for people to take seriously.
What I mentioned doesn't have to be taken to extreme to say nothing should be produced and moved around! By that analogy, the only way to save the environment is to stop living.
We are important. :)
Those not used can actually be used for baking pumpkin pies —though probably slightly different from regular pie pumpkins, but good enough.
So all things considered, this should not even register vs things like other festivals where there are tons of trash left over.
I was thinking and wondering if all those 1000s of acres could be used to grow something else, which people could eat and not throw away. :)
But you make a great point. It is better that we carve pumpkins, which are compostable, than use some kind of non-compostable stuff.
> We are completely fine growing so many pumpkins only for them to be carved and thrown away
We roast the seeds of any pumpkins we carve and compost the remains. The ones we don't carve get turned into pumpkin pie. We get immense satisfaction from the planning, carving, and displaying of our Jack-o'-lanterns.
> we buy a ton of costumes that are worn once and go to the landfill
We tend not to buy the cheap costumes, but instead assemble our costumes from a combination of costume parts and real items. We have chests full of this stuff and even if we don't use a particular item again, our spooky entity-creations do. The stuff will only end up in the landfill if my inheritors throw them away.
> we buy so many candies a lot of which probably gets thrown (which is probably better than eating them).
I eat all the candy. I give myself permission to eat less-than-great from Halloween to New Years. If I start getting some chub, I work out a little extra. I even did this when I was a body builder (just don't tell any of my trainers).
*Edit: HN-specific markdown...
Fixing humankind’s damage to the environment is going to take such sweeping societal changes that Halloween costumes and pumpkins shouldn’t even be a blip on our radar.
EDIT: I think so.
Also, roasted pumpkin seeds are easy, healthy, and delicious.
I wonder if after growing, harvesting, shipping, etc. a Halloween pumpkin is carbon negative.
