Ingabe isihlahla esizama ukuphila edolobheni singcono kunesihlahla esimila ehlathini? Impendulo esobala ingase ibonakale ithi “cha”: Izihlahla zasemadolobheni zibhekene nokungcola, inhlabathi empofu, nesimiso sezimpande esiphazanyiswa itiyela namapayipi.

Kodwa lapho izazi zemvelo e-Boston University zithatha amasampula abalulekile ezihlahleni ezizungeze i-Eastern Massachusetts, zithole isimanga: Izihlahla zasemgwaqweni zaseBoston zikhula ngokushesha okuphindwe kabili kunezihlahla ezingaphandle kwedolobha. Ngokuhamba kwesikhathi, ukuthuthuka okwengeziwe kwanda eduze kwabo, bakhula ngokushesha.

Kungani? Uma uyisihlahla, impilo yedolobha iphinde inikeze inani lezinzuzo. Uyazuza kunitrogen eyengeziwe nesikhutha emoyeni ongcolile wedolobha; ukushisa okubanjwe i-asphalt nokhonkolo kuyakufudumeza ezinyangeni ezibandayo. Kunokuncintisana okuncane kokukhanya nendawo.
