Kodi mtengo wofuna kupulumuka mumzindawu uli bwino kuposa mtengo womera m'nkhalango? Yankho lachidziŵikire lingawonekere kukhala “ayi”: Mitengo ya m’mizinda ikuyang’anizana ndi kuipitsidwa, dothi losauka, ndi dongosolo la mizu losokonezedwa ndi phula ndi mapaipi.

Koma akatswiri azachilengedwe a payunivesite ya Boston atatenga zitsanzo za mitengo yozungulira Eastern Massachusetts, anapeza zodabwitsa: Mitengo ya m’misewu ya ku Boston imakula mofulumira kuposa mitengo ya kunja kwa mzindawu. M'kupita kwa nthawi, pamene chitukuko chinawonjezeka mozungulira iwo, iwo anakula mofulumira.

Chifukwa chiyani? Ngati ndinu mtengo, mzinda moyo amapereka angapo ubwino. Mumapindula ndi nayitrogeni ndi carbon dioxide wowonjezereka mu mpweya woipitsidwa wa m’mizinda; kutentha kotsekeredwa ndi phula ndi konkire kumakutenthetsani m'miyezi yozizira. Pali mpikisano wochepera pa kuwala ndi malo.
