What are you unwilling to give up despite the likely fact that it contributes to global warming and the ultimate destruction of our planet?
Home, car, food, technology, consumer goods.
Harleys.
I don’t think there’s anything I own or use that “contributes to… the ultimate destruction of our planet”.
Single occupancy gas burning Jeep Wrangler.
Beef
Fewer cows, fewer methane emissions.
I doing my part but I can eat only so much.
Travel.
Same here. Old gas burning cars, trucks and motorcycles. Chainsaws, log-splitters and weed-eaters.
Recycle my water bottle. Seriously I don’t even know how to recycle where I live.
I’m unwilling to give up not going to jail.
Because if you give up everything we have that hurts the environment, it puts you at odds with law and society.
They have rules on where you can or can not sleep, what type of structure you can put where, and what you can and can not hunt catch or gather to eat and where and when you are allowed to do it and payment is expected for many things like living on a piece of land, or catching a fish, or hunting for some meat, and sometimes just for walking through some woods.
And they don’t accept one of the fish, or a tanned hide etc in trade as payment.
So eventually you wind up in jail
The other stuff, i’m ok without
Oh, and mowers, lawn tractors, root tiller, pontoon boat, etc.
I once camped with a group that included a guy who rigged together a little gas motor to a blender. He had a cooler of ice and made us blender drinks around the campfire.
So you live completely off the grid, grow and consume all of your own food, make all of your own clothes from renewable materials that you produced.
Good for you.
I have semi-electric car, and lawn mower. But I’m not giving up my gas powered boat. (and meat)
There is another option.
I bet he’s riffing off the old George Carlin routine, when pokes fun at “Save the Planet” campaigns. As George so eloquently put, the planet will be fine. It’s the people that are fucked.
Heat. I tried for a while to turn my heat down, especially at night, but found that being in a constant state of extreme discomfort made it impossible for me to accomplish anything. I still turn the heat down when I can, but I just need slightly higher temperatures than most people to function effectively, and I’m not willing to give that up.
I’m currently reading a very good book: The Wisdom of Frugality, that has a whole chapter about environmentalism, and some of the arguments both for and against individual choices. While the author ultimately comes down on the side of making the individual choice to live more frugally, she does a good job of pointing out when some activities really are nonsensical (for example, using more resources driving to the recycling center than you reclaim through your recycling).
Ah, yes. The “Margarita Machine”. Very popular in the off-road racing community.
Art.
In my studio, there is quite a bit of paper, a number of toxic, mostly petroleum derived, chemicals and other things that contribute (some in minute ways) to the degradation of the planet in and of themselves. However, I hope that the finished products that come from it balance the karmic equation. 
I abuse water.
I love long hot showers, I wash dishes and run the rinse tap the whole time, also with hot water. I flush the toilet even if it’s yellow. I wash half loads of clothes and cannot control the amount of water my washing machine uses. I run the tap before I pour myself a glass of aqua.
I justify it by saying I live in Canada, which is abundant in water. But purification plants, etc use chemicals and electricity. I know it would be better to use less. My son regularly turns off the water when I am doing dishes.
But … yes… I use way too much water.
