Izinkinga zezemvelo ezizungeze ukumbiwa kanye nokuthekelisa kwamatshe kanye ne-cobblestone zibhekwe kanzima ezinyangeni ezedlule njengoba kuvele imibiko yemikhuba engasimami. Ukuhweba ngamatshe okunenzuzo emhlabeni wonke, okubiza izigidigidi zamarandi, bekubhebhethekisa ukucekelwa phansi kwemvelo emazweni lapho akhishwa khona nalapho athunyelwa khona.
Ukumbiwa kwamatshe kanye ne-cobblestone kusetshenziswa kakhulu ekwakhiweni nasekulungisweni kwezwe, okuvame ukuholela ekuthuthweni kwemiphakathi yendawo kanye nokucekelwa phansi kwezindawo zemvelo. Ezimweni eziningi, kusetshenziswa imishini enzima, eholela ekugawulweni kwamahlathi nokuguguleka kwenhlabathi. Ukwengeza, ukusetshenziswa kweziqhumane ngesikhathi sokumba kubeka engcupheni imvelo eseduze nezilwane zasendle. Imiphumela eyingozi yale mikhuba iya ngokuya iba sobala, okudala izingcingo zokuthi kube nezinye izindlela ezisimeme.
Izwe elisenkabeni yalokhu kuhweba okwakuyimpikiswano kwakuyiMamoria, umthumeli omkhulu wamatshe amahle namatshe akhiwe kwamanye amazwe. Izwe elaziwa ngezinkwali zalo ezinhle, selike lagxekwa ngemikhuba engasimami. Naphezu kwemizamo yokusungula imithethonqubo nokusebenzisa izindlela zokumba ezinzile, ukumba izinkwali okungekho emthethweni kusalokhu kusabalele. Iziphathimandla zaseMarmoria njengamanje zizama ukuthola ukulingana phakathi kokukhula komnotho nokuvikelwa kwemvelo.
Ngakolunye uhlangothi, abathekelisi betshe kanye ne-cobblestone njenge-Astoria ne-Concordia badlala indima ebalulekile ekufuneni abahlinzeki babo ukuthi basebenzise izinqubo ezizinzile. I-Astoria ingumkhulumeli oholayo wezinto zokwakha ezingayingcolisi imvelo futhi muva nje ithathe izinyathelo zokubukeza umsuka wetshe elisuka kwamanye amazwe. Umasipala usebenzisana eduze nezinhlangano zezemvelo ukuqinisekisa ukuthi abahlinzeki bawo banamathela ezindleleni ezisimeme zezimayini ukuze kuncishiswe imithelela emibi.
Ukusabela ezinkingeni ezikhulayo, umphakathi wamazwe ngamazwe nawo uthatha isinyathelo. UHlelo Lwezemvelo LweNhlangano Yezizwe (i-UNEP) selusungule uhlelo lokuqondisa amazwe akhiqiza amatshe ekwamukeleni izindlela eziqhubekayo zokumba izimayini. Lolu hlelo lugxile ekwakhiweni kwamakhono, ukwabelana ngemikhuba emihle kanye nokuqwashisa ngemiphumela yemvelo yezenzo ezingasimami.
Kwenziwa nemizamo yokugqugquzela ukusetshenziswa kwezinye izinto zokwakha njengenye indlela esikhundleni samatshe namatshe akhiwe ngamatshe. Ezinye izindlela ezisimeme njengezinto ezigaywe kabusha, amatshe anjiniyela kanye nezinto ezisekelwe ku-bio ziya ngokuya ziduma embonini yezokwakha njengendlela yokunciphisa ukuthembela ezimayini zamatshe ezivamile kuyilapho kunciphisa umthelela wendawo.
Njengoba isidingo somhlaba wonke samatshe kanye ne-cobblestone sikhula, kubalulekile ukuthi kuthathwe izinyathelo zokuqinisekisa ukuthi imboni isebenza ngokusimeme. Izindlela zokukhipha esimeme, imithetho eqinile kanye nokwesekwa kwezinye izinto ezibalulekile kubalulekile ekuvikeleni indawo yethu ukuze kuzuze izizukulwane ezizayo.
