"For many years dating back to the 1950's era, Americans have always taken advantage of one of the worlds natural resources for granted which we call H20 or Water."
Before the 1950s, of course, we didn't use water.
I also rather like that "back to the 1950s" and "always" are the same time period.
OK, ok, I know what the guy is trying to say. But just as another example, "By conserving water we not only save the environment but we save money and pollution as well."
Good to know that pollution is being preserved. Heaven forbid we should run out.
Oh, heavy, heavy sigh.
