Regarding TV shows "The Colony", "Survivorman" and "Man vs. Wild"

Now, just to start off with here I want to say this: I enjoy watching these shows. I learn something from each show. It may be how to make a fire or a shelter a certain way, how to climb down a small cliff with vines, how to not do something stupid Mr. Grylls does, or how to make a wood gasifier. Here are a few complaints about these shows that have been on my mind (besides Mr. Grylls' stupid and dangerous behavior at times).

Regarding "The Colony"...

• Why is this show set in a setting of an industrial park with tons of industrial equipment and such around? How realistic is this? Why not show how a small neighborhood or apartment/condo community would come together to divide up duties, make life as normal as possible where they live, provide security for themselves and survive?
• Why not address the reality of guns existing in such an aftermath situation and the proper use and concerns associated with weapons and mauraders (rather than gawking, food throwing monkey like raiders)?
• Why not address troops (domestic, UN or otherwise) trying to force their will upon an unwilling group of survivors?

In general...

• Why is the issue of dealing with human waste never addressed (other than the basically urban situation on "The Colony", which goes as far as "good thing the toilet flushes!")?
• How about some basic sheltering in place and some real homesteading type educational programming?
