I was asked recently to write a short essay on environmentalism to be published in a book on âKey Concepts in Critical Management Studiesâ to be published by Sage later in 2010. I hope itâs useful for those who want a little bit of history and critical understanding of environmentalist as a concept and a movement.

Hand sorting the 1982 Copper from the Zinc pennies. 1982 was the transition year for the US Mint to stop making pennies from copper and switch to zinc. There are sorting machines that can be purchased to do this work, but if you dont have a machine, your ears can do the job!
Why Not Pennies? You may ask, why not accumulate 95% copper (pre-1982 mint date) pennies? They already seen a spike in their base metal value to 2.2 cents each. But unfortunately, pennies have two problems: confusion and bulk. They are confusing, because 95% copper pennies are now circulating side-by-side with 97.5% zinc pennies. They are also about four times as bulky (per dollar of face value) as nickels. With nickels you wonât have to spend time sorting out pre-1982 varieties. At present, visually date sorting pennies simply isnât worth your time.
