Here's something to think about if you're planning on tuning in to Joel Lambert's new survivalist show ... everyone involved with filming on location is probably carrying around bags full of their own excrement.

The former Navy SEAL was back in LA after filming "Lone Target" -- his new show on Discovery Channel that forces Joel to escape capture by elite military forces around the world.

So we asked him a lot of crap ... and the rules are simple ... when you're on the run leave no trace in the wild ... so producers, camera guys, and even Joel himself, had to pick up and carry around their turds.
