Njengoko sibonile kwinqaku Ukukhula koqoqosho okanye ukuzinza kwendalo?Kukho abantu abakholelwa ukuba ukukhula koqoqosho akunasiphelo ngexesha. Kodwa inyani yahlukile okwahlukileyo. Ukukhula koqoqosho kusekwe ekuxhatshazweni nasekusebenziseni izinto zendalo esinikwa yiplanethi yethu. Kodwa ezo oovimba balinganiselwe kunye nenqanaba lokuphinda kuhlaziywe kufuneka libe sezantsi kunenqanaba lokuxhaphaza ukuze uqhubeke nokuxhamla kubo. Eso siphelo saziwa ngokuba yimida yeplanethi.
Umntu, emva kwenguquko kwimizi-mveliso, ulonyusile inani labantu kwihlabathi kwaye oku kukhokelele ekwandeni kokuxhatshazwa kwezixhobo zendalo. Oko kuxhaphaza kukhulu kakhulu kangangokuba sele igqithile kumthamo wokuthwala indalo, ekhokelela kunqongophala kwendalo.
Kukho imida eli-9 yeeplanethi: Ukuphela kwezilwanyana, ukutshintsha kwemozulu, ukonakala kweozone, ukufakwa kweasidi yolwandle, ukuntywila kwemichiza, ukusetyenziswa kwamanzi amatsha, utshintsho kwinkqubo yoMhlaba, ukulahleka kwendalo kunye nemisebenzi kunye nezinto ezintsha.
Namhlanje ukusetyenziswa kunye neepateni zemveliso yenkqubo yethu yezoqoqosho sele yenziwe ezine kwimida yeeplanethi. Le mida yiyo eqinisekisa ukusebenza ngokukuko koMhlaba nazo zonke iinkqubo zawo ezintsonkothileyo ezisebenza ngolungelelwano olunengqiqo.
Utshintsho lwemozulu, izinga lokuphela kweentlobo, utshintsho ekusetyenzisweni komhlaba kunye nokuguquguquka kwe-biogeochemical phosphorus kunye ne-nitrogen ziinkqubo esele zigqithile. Oku kuthetha ukuba kwandisa umngcipheko okubandakanya ukuqhubeka nokwenza imisebenzi yoluntu ngeli nqanaba. Olunye uvavanyo lwenzululwazi lusebenza ukuqinisekisa ukuba ukusetyenziswa kwamanzi amatsha sele kugqithisiwe kwaye kongezwe kuluhlu lwemida yeplanethi egqitha kumda okhuselekileyo.
Indalo inendlela yokukwazi ukungenisa iimpembelelo zabantu kwindalo yayo kwaye kungenxa yezi mpawu zomzimba kunye nezebhayoloji ukuba iplanethi yethu ihlale izinzile iminyaka emininzi esinokuhlala kuyo "ukuvumelana". Nangona kunjalo, ikho ukungaqiniseki kwezenzululwazi Phambi kokuba iziphumo zokugqwetha kwezi patheni zigcina iplanethi izinzile kunokubangela. Kungenxa yoko le nto sizifumana sinekamva elingaqinisekanga elinokuhamba kunye utshintsho olungenakulungiswa kwizixhobo esixhomekeke kuzo ukuze siphile.
Ngokubhekisele kumda wamanzi amatsha, indawo yokusebenza ekhuselekileyo yokusebenzisa amanzi iyafundwa. Into eyaziwayo enkosi kwi-Living Planet Index, kukuba amanzi amatsha abonisa ukuba alahlekile Iipesenti ezingama-81 zabemi phakathi kowe-1970 nowama-2012.
Kwelinye icala, umda wotshintsho lwemozulu ulinganiswa ziingxinano ze-CO2 kwiatmosferi nezinye iigesi zegreenhouse. Sikwanomda ukwanda kweedigri ezimbini kumaqondo obushushu aphakathi komhlaba. Kule nto, ubuninzi be-CO2 akufuneki budlule 400 ipm. Nangona kunjalo, Ukugxininiswa komyinge okugqityiweyo kugqityiwe kabini ngokulandelelana.
Kukho eminye imida yeplanethi ebonelela ngokungaqiniseki okukhulu kwezesayensi xa ubulinganisa kwaye ubhala. Umzekelo, Ukuphulukana nemisebenzi yendalo kunzima ngakumbi ukulinganisa. Ukuvela kweemveliso ezintsha, ezinje ngezinto eziguqulweyo zemfuza okanye inkunkuma eqhumayo, kukwangumda weplanethi ekunzima ukuwulinganisa kunye nokugcina iirekhodi okanye ukwenza iziphumo ezinokugqithisa.
Uncedo, ngokutsho oko, kukuba yonke imida yeeplanethi inxulumene. Iyantlukwano kunye nemozulu zizinto ezimbini ezigcina imeko ezinzileyo ekufuneka iplanethi iqinisekise ubomi esibuphilayo. Ezi zinto zezona zinokumelana ngcono nefuthe leminye imida yeeplanethi. Oko kukuthi, i-ecosystem eneentlobo ezahlukeneyo zezinto eziphilayo kunye nenani elikhulu leentlobo, inokuxhathisa ngcono iimpembelelo ukuba sicaphukise kuyo, kuba kukho inani elikhulu lobudlelwane kunye nokuxhomekeka phakathi kwabo.
Olunye utshintsho kwimida yeplanethi lunokubuyiselwa umva ngamanyathelo angqingqwa kunye nexesha elaneleyo, njengoko kwenzekile nokwehliswa komngxunya kumaleko weozone emva iProtokholi yaseMontreal kunye namanyathelo okususa i-chlorofluorocarbons (CFCs) kwiifriji nakwiinkqubo zeerosol. Kwezinye iimeko, ingxaki inokumiswa kuphela, kodwa ukubuyela kwimeko enjalo akunakwenzeka, njengoko kwenzeka ngokuphela kweentlobo.
Kodwa into ekufuneka siyithathele ingqalelo kukuba nantoni na esiyenzayo, masiqhubeke ukuguqula iplanethiKungenxa yoko le nto kufuneka siqinisekise ukuba olu tshintsho alunakulungiseka kwaye lusivumele ukuba siqhubeke nokonwabela iimeko esihlala kuzo ngoku.
