I'm not sure what you're trying to say. Because homeless people litter, you shouldn't have to cover the load of trash you're hauling to the dump in your pickup? If they're going to litter, you should be able to litter too?

We've been cleaning up the homeless camps for years, and evicting the homeless from them, so I'm not sure what else you think we could be doing, or why that perpetual issue should keep us from making progress in other areas.

And perhaps most importantly, none of this has anything to do with reducing greenhouse gas emissions.
