Approach #1. The Smear Campaign. Like its name implies, researchers claim that by smearing your poop thinly over rocks, the sun's UV radiation will sterilize your poop and it will eventually wash away with time and will no longer impose any health risks. Wow, I will forever look at a peanut butter and jelly sandwich differently, what a shame!
Approach #2. No pun intended! Pack it out. Now, they say, that this is the single best option for the environment but it definitely isn't for the faint of heart, or pretty much everyone I know, so let's move on.
Approach #3. The Toss. Sometimes when traveling through a steep, rocky environment, it can be quite precarious, and sometimes impossible, to leave the trail for fear of falling down a ravine, crevasse or off a cliff. So in this situation it's suggested that you merely throw your poo, out and away from the trail where others are unlikely to be. But use common sense and before you throw it yell, "lookout below!"
Approach #4. Bury it. This old fashion but highly reliable method is by far my favored approach to waste disposal in the woods and is the tidiest, as well. You simply find a spot, that's at least 200 feet from any water source, dig a hole roughly six inches deep and wide and once you are finished, you cover it back up.
And finally, approach #5. The Clench. Now the design of this glorious idea is that you don’t actually take a poop. You just tough it out for two, three, sometimes five days, because you are deathly afraid of crapping in the woods and getting it all over your hands.
So, ultimately, respect "Mother Nature" and don't just poop all over her. Be mindful of those around you and rigorously follow the proper practices and regulations in the area that you'll be recreating...and pooping in!
