This isn't so much of a "survival" video for hiking on the trail, but it is essential, and it is a big deal when it comes to keeping the trail clean and beautiful for yourself for other hikers!
This guy is giving advice from the trail (awesome idea!! maybe I should try it...) and not only talks about handling your own trash, but also talks about packing out other people's trash when you come across it. Ziplock bags are the one of the best things you can have on the trail. Especially when it comes to repackaging food and packing trash! Bring a bag full of bags that you can have extras with and pack out as much extra trash as you can.
Don't be disrespectful of other hikers--be a kind, smart hiker!
I won't rewrite all of his tips here because he explains it far better than I could....just watch!
