Let­ters In Brief

Weekend Post (South Africa) - - THIS WEEK YOU’RE SAYING ... -

GREEN par­ties could play the blues to solve global warm­ing: In some places day­light per­sists much longer than other places and near the Arc­tic Cir­cle one has very long days in sum­mer and phy­to­plank­ton ad­justs to this.

Phy­to­plank­ton re­moves huge quan­ti­ties of car­bon diox­ide from the at­mos­phere by us­ing green and blue light to flour­ish. But it is harmed by ul­tra­vi­o­let light.

At night, when there is vir­tu­ally no ul­tra­vi­o­let light, ir­ra­di­ate the ocean with green and blue light. The lights could be on tall poles on land while peo­ple dance on the sand. This would cre­ate a tourist at­trac­tion.


I AB­SO­LUTELY loved Casper Lot­ter’s opinion piece (Week­end Post last week). He wrote about a very se­ri­ous mat­ter in­ter­spersed with com­ments that had me laugh­ing from “toe­nail ex­trac­tion”, “un­con­trolled bal­lis­tic mis­sile” to “wreck­ing ball”. My imag­i­na­tion was work­ing over­time and re­minded me that some­times all you can do is laugh, to keep your­self from cry­ing.
