Based on a 2020 National Litter Study, the US produces about 24 billion pieces of roadside litter every year, and another 24 billion pieces can be found along waterways. You can see it everywhere you go, along every road or riverside in the country. Large metropolitan areas tend to have the most roadside litter per capita, but highways definitely represent the most roadside litter per mile. Litter is an epidemic, decreasing the value of regions and encouraging more litter as people think their little bottle or cigarette will simply be joining millions of "friends".
