If you see a bag of trash stop and pick it up. Plain and simple. Yes it takes about 10 min of your life to do this, but guess what, if everyone did that there would be no issue. I've done it everytime I've driven 127, which is quite a bit considering I live in Pahrump and have family in LA. As for the black tanks being dumped, that's just plain disgusting. If you aren't going to be responsible about that then you don't need to be alive, IMO.
