The four most impactful lifestyle choices you can make to reduce your effect on climate [1] are:
* have fewer children
* live car-free
* become vegetarian
* avoid transatlantic air travel
I now live car-free and vegan. I've no kids, yet (maybe never). I live in California but I'm from Ireland - I'll probably take a flight home soon.
So no, I don't totally avoid everything that can cause harm, but at least I try.
What is ludicrous is using a car for journeys under ten miles.
It is abhorrently selfish to do so knowing that your pollution contributes to sickness in people.
People should maybe take a pay cut, or live in a smaller home, closer to where they work. But instead they trade the health of others for their own standard of living. ("some of you may die, but that's a price I'm willing to pay")
> Most drivers cannot practically manage walking/biking or public transit as their sole means of travel.
In a large part because of cars. Cars beget cars. Car companies conspired to shut down public transit. Now people in those areas need a car. Then it's held as a example of why we need cars.
Urban sprawl was enabled by cars. Now people need cars to get to those areas.
It's very difficult to find a problem that cars solve that wasn't itself caused by cars.
What is ludicrous is to call how I actually live ludicrous. I enjoy a high standard of living. Without a car.
