Maruva chiratidzo chechimwe chinhu chakanaka uye chakanaka. Vatsvakurudzi vave vachitsigira kwenguva refu migumisiro yakanaka iyo miti yemaruva ine pamamiriro emanzwiro. Kuvandudza mafungiro nekumhanya kwemheni, maruva aida vakadzi venguva dzose uye vanhu nokuda kwechikonzero.
Chidzidzo chemaitiro chakaitwa paYunivhesiti yeNew Jersey inotungamirwa napurofesa wepfungwa Jeannette Havilland-Jones. Boka revatsvakurudzi rakadzidza hukama pakati pemavara uye kugutsikana kwehupenyu pakati pevatori vechikamu pamusoro pemwedzi gumi. Sezvineiwo, mhinduro yakacherechedzwa ndeyepasi rose uye yakaitika mumapoka emazera ese.
Maruva ane nguva refu yakanaka pamafungiro. Vatori vechikamu vakashuma kuderera kwekuora mwoyo, kunetseka, uye kufara mushure mekugamuchira maruva, nekuwedzera kwekunakidzwa kwehupenyu.
Vanhu vakura vanoratidzwa kuwana nyaradzo mukukomberedzwa nemaruva. Vanokurudzirwa zvikuru kutarisira zvirimwa, kurima gadheni uye kunyange kugadzira maruva. Tsvagiridzo inoratidza kuti Maruva ane hupenyu hwawo, kutepfenyura simba rakanaka, kuunza mufaro, kusika, tsitsi uye kugadzikana.
Kana zvasvika pakushongedza imba yemukati, kuvapo kwemaruva kunozadza nzvimbo nehupenyu, kwete kungoishongedza chete, asiwo kunopa mhepo inodziya uye inogamuchirwa. Izvi zvinosimbiswa nebepa rinonzi "Kudzidza Ecology Kumba" rakaitwa paHarvard University:
NASA masayendisiti akawana angangoita makumi mashanu emba uye maruva ayo. Mashizha nemaruva ezvirimwa zvinonatsa mweya, kuburitsa okisijeni nekutora muchetura une njodzi senge carbon monoxide uye formaldehyde.
Kana iri ruva rakachekwa rakamira mumvura, zvinokurudzirwa kuwedzera chipunu chemarasha, ammonia, kana munyu kumvura kuitira kuderedza kukura kwebhakitiriya uye kurebesa hupenyu hweruva. Cheka hafu yema inch yedzinde zuva rega rega uye shandura mvura kuti uchengetedze kuronga kwemaruva kwenguva refu.
