    I responded somewhere above in the conservation.

    It was something I heard this professor say in a podcast and there was also a newspaper article about it.

    This English items doesn’t say the straw bit, but it does say 4KG of microplastics during its lifetime

    https://www.theguardian.com/environment/2020/jul/14/car-tyres-are-major-source-of-ocean-microplastics-study

    After some Googling, a car tire will last about 50K miles. After 50K miles it has lost 4KG of microplastics. A car has 4 tires so 16KG.

    16000 grammes per 50K miles, is almost 1 gram per 3 miles.

    First Google result Straws on average weigh so little—about one sixty-seventh of an ounce or . 42 grams
