Ban on polystyren

In reading Mr. Rudolph Silva's letter (Sept. 13), he offers a very simplistic argument regarding polystyrene dangers due to the chemicals used in its manufacture. He fails to mention that the chemicals used in its manufacture no longer exist in their original form.

There are many products used in every day life that are derived from very dangerous chemicals, but when reacted , have no harmful effects.

A simple example of two products are common table salt, and essential oils (fragrances). Table salt is comprised of sodium and chlorine, both very toxic and dangerous to the human body. Essential oils are typically made from sulfuric and nitric acid and various other materials, but when reacted together, present a very pleasant fragrance used by many people.

Mr. Silva's comments are typical of many environmental groups They typically present the most dangerous arguments, but always fail to mention the facts.

Bravo, militia

If Robert Zanker, Concord (Sept. 10 letter), has ever met a gun owner or a member of the NRA, then he's met the militia.

That militia (so many gun owners) is a huge reason this country has not been invaded since the Revolutionary War. And then, it was the militia that began the fight to get this nation the freedoms we have.
