One of the first things my instructor told me was “I hope you’re getting your license for fun or a job, and not planning on commuting. Eventually you’ll get stuck somewhere due to the weather.”

Heavy, powerful commercial jets have deicing systems. They also have the benefit of an entire team of air traffic controllers on takeoff and landing – and they still get grounded by weather. Small planes are grounded by such inclement weather as “fog”, “thunderstorms”, “high winds”, and “low cloud cover”.

Speak for yourself, I bike with a bag on my head to capture my emissions.

bike pollution is slightly more than nil just because of the CO2 we breathe out while riding

Technically, the CO2 animals exhale is carbon neutral because it’s from plants you eat (or your food eats). Unless you’re eating petroleum derived products of course.

I say technically because while the plants themselves are carbon neutral, modern food production and distribution, especially meat production, still has a large carbon footprint. So your breath is only truly carbon neutral if you foraged for food in the forest on foot.

Don’t forget that many small propeller driven aircraft run on leaded gas, and it’s a formulation of leaded gas that has 10x the lead that motor fuel used to.

Small aircraft have a carbon equivalent to large cars. My plane is from 1961 and has a fuel economy of 15mpg as the crow flies (arguably closer to 25mpg because of straight line measurements versus winding roads that can almost double the distance), seats 4 people comfortably, and flies at 160 mph.

Breathing isn’t pollution

Walking pollution: …

That’s right, bike pollution is less than walking (or running) pollution in terms of CO2 per mile travelled. Cycling typically burns ~⅓ of the calories compared to making the same journey on foot and there’s a direct link between calories burnt and CO2 produced.

Cycling at 12mph takes roughly the same energy as walking at 4mph. You emit the same CO2 per minute, but get there in ⅓ of the time. Running at 12mph takes 3 times the effort of cycling at 12mph. You’ll get there in the same amount of time, but breath out 3 times as much CO2. Bicycles are more efficient than our own two legs - how cool is that!

I gave up flying to have kids. Probably worse for pollution

I’ve got to ask, though—how is breathing CO2 pollution? Aren’t we just taking in air, removing the oxygen, and exhaling the waste gases? Isn’t there the same net CO2 afterwards?

Have I misunderstood something as simple as breathing? Please say no.

But, do that people have light aircrafts or motherfucking Boeings 787?

I feel like it should be … for the amount of gas I release while cycling.

Try reading that comment with a TTS engine. Lol

as if rich people care about how much they pollute

Cycling has carbon emissions if you factor the additional calorie intake needed to power your bike. :| Which will vary widely depending on your size, diet, and food source. Is it still a more sustainable form of transportation? Probably, but maybe not in extreme cases (like a 300-lb person eating beef daily flown in from the other side of the planet, versus, a tiny two seater electric car power off of solar energy, using batteries sourced from recycled materials) and it certainly isn’t 0 impact.

Also, for extra pedantism, carbon emission are not pollution (in the sense that it doesn’t poison the life forms directly), but it is a GHG which causes harm to the environment too.

Plane pollution is not that much worse than a car. Depending on what metric you measure it can be better (planes are more fuel efficient and thus less CO2. Small planes like the picture generally use lead fuel and old engine designs that pollute more) on long trips.

You’re only taking into account pollution and i bet you with the barrier of entry and cost accounted there would be less pollution from flying compared to driving.

much more strict.
