One of the reasons I quitted Amazon Prime was ecology.
My neighborhood is plagued with Amazon delivery vans.
They are everywhere, double parked, which makes traffic a mess in a place that used to be a quiet neigborhood.
I am sure Amazon has no idea about how many CO2 they emit, since most of them are freelance contractors.
But since they don't pay much, they have no low emission vehicles, and makes the rest of the people emit more CO2 since they double park everywhere.
