UMfula iNayile odume njalo bekukholelwa ukuthi yiwo omude kunayo yonke emhlabeni, kepha kuthiwani uma bekungenjalo? Ukukala le mifudlana akulula njengoba kuzwakala, hhayi nakubadwebi bamabalazwe be-hydrographic njengoba kuya ngezici ezahlukahlukene: isikali sokulinganisa esisetshenziswayo, lapho kuqala khona umfula omunye uphela (njengoba imifudlana eminingi ihlangana nezinhlelo zemifula), ubude bayo noma ivolumu.
Ochwepheshe abaningi bathi umfula omude kunayo yonke emhlabeni empeleni yi-Amazon. Kepha kungani kunempikiswano engaka ngale ndaba? Uyini ngempela umfula omude kunayo yonke emhlabeni?

Uma sibheka ukugeleza kwayo, umfula waseMelika uyinkosi yayo yonke imifula kwazise ithumela isilinganiso sama-cubic metres ayi-200.000 njalo ngomzuzwana ku-Atlantic Ocean. Linjalo-ke inani lamanzi elihliphayo ukuthi ngezinsuku ezinhlanu nje lingagcwalisa lonke iLake Geneva (amamitha ayi-5 ukujula namakhilomitha angama-150 ubude). Kuyamangalisa impela.

Iphi impikiswano ke?

Ngubani onesizathu?
Umphakathi wesayense jikelele uyaqhubeka nokugcizelela ukuthi uMfula iNayile mude kunayo yonke emhlabeni. Ngubani onesizathu? Akwaziwa nakanjani ngoba udaba lusaphikiswa. Yize, inikezwe ububanzi nevolumu yayo enkulu, mhlawumbe kungadingeka ukuncika ngase-Amazon.
