Lovely tone, you sound like a really nice person.

I never mentioned train wheels at all. Their brake pads are made from things like carbon, ceramic, and resin compounds. These wear down like any brake pads and so cause the same dust pollution. Remember that some trains in the world are over a mile long and have over 1000 wheels.

I dont see anybody claiming that bikes or trains cause anywhere near the same level as cars, but it is important to remember that they still do cause some and so they are not a silver bullet. Solutions still need advancing in order to completely remove these pollutants from human transportation systems.

'Bikes cause it too' is technically true in the way that a dripping tap and a burst dam both cause flooding. The effect of this framing (intentional or not) is to suggest we shouldn't prioritise the thing that causes 99.99% of the problem until we've solved the thing that causes 0.01%. That's not a serious position, you're just protecting your comfort.

Have you ever seen the damage a dripping tap can do? I have seen houses completely wrecked by it.

Stop protecting your argument by trying to say something small doesnt matter. It all matters, regardless of size.

If the argument is that microplastics are harmful to health, surely we should be looking at all sources of them instead of just the biggest?

My argument is 'Lets try to make all vehicle tyres and brakes from something that doesnt pollute the earth and harm animal life on it.'

Yours seems to be 'Lets ignore the plastic pollution from other transport because cars cause the most, so thats all we need to worry about.'

You are welcome to edit your comment to clarify.

No need, it is correct.

Bikes have tyre pollution, and trains have brake pollution. Seems like a pretty simple statement to me.

Interesting that you have moved from arguing the point into semantics now without addressing anything else. You are welcome to remove your downvotes.

People seem to get very upset when others point out that transport like bikes and trains still cause the same pollution as cars. yes it is much less, possibly orders of magnitude so, but they still cause it. Perhaps instead of getting the pitchforks out we could work together to find better wheel and brake solutions for all transpotation methods which dont cause so much toxic dust.
