Why there´s a need for "The Archaeology of the Recent Past"

I think this documentary clearly illustrates the need for archaeology of the recent past. It also shows some interesting approaches as to how fieldwork can be done on town sites. It should also (of course) be clear to everyone that children can´t participate on  regular WW2 battlefield archaeology digs because of security issues.

Enjoy :) !
