Ngaba umthi ozama ukuphila esixekweni ulunge ngakumbi kunomthi okhula ehlathini? Impendulo ecacileyo ibiya kubonakala ngathi “hayi”: Imithi yesixeko ijamelene nongcoliso, umhlaba ombi, nenkqubo yeengcambu ephazanyiswa yitela nemibhobho.

Kodwa xa izazi ngendalo kwiYunivesithi yaseBoston zathatha iisampulu ezingundoqo kwimithi ejikeleze iMpuma Massachusetts, zafumanisa isimanga: Imithi yesitalato saseBoston ikhula ngokuphindwe kabini kunemithi engaphandle kwesixeko. Ngokuhamba kwexesha, okukhona uphuhliso lusanda kubangqongileyo, kokukhona bakhula ngokukhawuleza.

Ngoba? Ukuba ungumthi, ubomi besixeko bukwabonelela ngeenzuzo ezininzi. Uyangenelwa kwinitrogen eyongezelelekileyo nekharbon diokside kumoya ongcolileyo wesixeko; ubushushu obubanjwe yi-asphalt kunye nekhonkrithi bufudumeza kwiinyanga ezibandayo. Kukho ukhuphiswano oluncinci lokukhanya kunye nendawo.
