Just suppose for a minute that I was thinking of investing some hard-earned shekels in QRN. Hey - those pictures on TV ? Is that COAL they are carrying ? Pardon me ??? - but is not COAL mainly constituted of CARBON ??? Is this the same CARBON that Saint Julia of GreenLabor is exhorting us all to cease including in our lives ?? As in "reduce our CARBON footprint" ? I am puzzled - confused that QRN could possibly be a great investment as a COAL hauler - if CARBON is presumably so bad. Can somebody please clear this up for me and convince me that:- [A] coal hauling can have a great future. [B] We can obey Saint Julia and reduce our carbon footprint. Many thanks.
