Zašto reke menjaju boju?

Blog
Mnogo je vode Dunavom proteklo od doba čuvenog kompozitora Johana Štrausa Mlađeg do danas. Zub vremena nagrizao je i tada romantičarsku sliku druge najduže evropske reke - od lepe i plave svojevremeno do ne tako lepe i ne tako plave sada. Umesto "na lepom, plavom Dunavu", čini se, plovimo "na Dunavu". Slično kao kod devojaka, lepotu reka narušava plastika u ogromnim količinama, a zbog čega menjaju boju? Da li žute od zavisti, zelene od muke ili crvene od stida? Ili pak d) sve od navedenog? Ili pak e) ništa od navedenog?
