It is not specific enough

A research must have a well-defined object. In this way, the researcher needs to choose something specific. In that case, the question "Is recycling effective in the United States?" is very broad. What kind of recycling is being talked about? Of glass? of pastic? of rubber? of trash? Anyway, a survey on recycling is perfectly possible, but needs to be better specified.

For example: it is possible to analyze a city that recycles its garbage has satisfactory results that make the difference for the environment.
