Izimbali nezilwane kwakha izinhlobonhlobo zezinto eziphilayo emhlabeni. Umuntu ubangela i- ukulahleka kwemvelo emhlabeni jikelele okudala izinkinga zangempela emhlabeni. Sicabanga ukuthi into ebaluleke kakhulu ngamadolobha nezakhiwo lapho silahlekelwa yiyo yonke imvelo yethu yemvelo.
Lapha sizochaza ukuthi yini ukulahleka kwemvelo kanye nezimbangela eziyinhloko nemiphumela okukuyo emhlabeni wethu.
Kuyini ukuhlukahluka kwemvelo
Lapho sikhuluma ngezinhlobonhlobo zezinto eziphilayo, sizobe sibhekise kuzo zonke izinhlobo zezinto eziphilayo ezikhona emhlabeni. Okungukuthi, ku-ecosystem, ngokwesibonelo, kunezinombolo eziphelele zezinto eziphilayo ezihlala kuyo. Leli nani eliphelele lezinto eziphilayo yilokho esikubiza ngokuthi yi-biodiversity. Akunandaba nenani labantu, i-ecosystem ingaphakama noma yehle ngokuhlukahluka kwemvelo kuya ngenani lezinhlobo zezinto eziphilayo. Uma singabhekiseli kwinani labantu abahlala kuleyo ndawo yemvelo yohlobo ngalunye, sizothi kungukuchichima kwalo.
Ngokuqondene nezidalwa eziphilayo, zingahlala kunoma yiluphi uhlobo lwe-ecosystem oluphakathi kwamathafa, amahlathi, amahlathi, imvelo eyahlukene yamanzi ahlanzekile nosawoti. Ukubaluleka kokuhlukahluka kwemvelo kutholakala kunani langaphakathi. Futhi kungukuthi, yize abaningi bengakwazi, Izinhlobonhlobo zezinto eziphilayo zinikela ngenani elikhulu lezinsizakalo nezimpahla kubantu ezibalulekile ekusindeni. Phakathi kwalezi zimpahla nezinsizakalo sithola ukudla, amanzi, izinto zokusetshenziswa nokunye imithombo yemvelo.
Imiphakathi eminingi ehlala ezindaweni zasemakhaya incike ngokuphelele kulezi zinsizakalo ezinikezwa ukuhlukahluka kwemvelo.
Izimbangela zokulahleka kwemvelo
Inkinga yokulahleka kwezinto eziphilayo inkulu kakhulu emvelweni. Ikhiqizwa ngokwengeziwe ngokuqhamuka nemingcele. Kulinganiselwa ukuthi cishe ama-36% azo zonke izinhlobo zezinto ezisengozini yokuqothulwa. Kumele kucatshangwe ukuthi ukuncishiswa kwezinto eziphilayo ezahlukahlukene kwenzeka ngesivinini esisheshayo endaweni yasemanzini.
Izizathu eziyinhloko zokuthi kungani izidalwa eziphilayo zinqotshwa ezandleni zabantu yilezi:
- Ukusetshenziswa ngokweqile kwemithombo yemvelo. Umuntu udiliza imithombo yemithombo yemvelo futhi eshiya ngemuva imikhondo emikhulu yokungcola. Ukungcola kwazo zonke izinhlobo ezibanga, zona, zivuseleleke kabi imvelo kanye nomonakalo omkhulu kwezinye izinhlobo ezincike kuwo.
- Ukulahleka nokonakala kwezindawo zemvelo. Ukuze izinhlobo zezinto eziphilayo ziphile zidinga indawo yokuhlala yemvelo. Ngokusetshenziswa ngokweqile kwemithombo yemvelo esishilo ngaphambili, izindawo zokuhlala zihlukanisiwe, zehlisiwe futhi azinazo izimo ezidingekayo zokuthi izidalwa eziphilayo zikhule.
- Ukungcola. Ngenxa yezimbangela ezingenhla, kukhona ukungcoliswa kwamanzi, inhlabathi nomoya. Lokhu kungcoliswa kwehlisa izinga lempilo kanye nemvelo edala umonakalo.
- Isingeniso sezinhlobo ezihlaselayo. Izinhlobo ezihlaselayo zinesici esikhethekile sokukwazi ukuphila endaweni yemvelo okungeyona eyazo. Lokhu kungenxa yokuthi izidalwa ezihlasela imvelo zincane noma azikho nhlobo noma ukuthi isimo sezulu nezimo zezemvelo zikusekela ngokuphelele ukukhula kwazo.
- Ukuguquka kwesimo sezulu nemiphumela yako emibi. Isamba sazo zonke izimbangela ezingenhla sidala futhi sandisa imiphumela yokuguquka kwesimo sezulu. Izinguquko esimweni sezulu ezivumela izimbangela ezingenhla zenzeke ngamandla amakhulu nobuningi.
Imiphumela yokulahleka kwemvelo ehlukahlukene
Njengoba kunikezwe zonke izimbangela esizihlaziye phambilini, manje yisikhathi sokubona imiphumela okumele ibonwe yizinhlobonhlobo zezinto eziphilayo. Into okunzima ukuthi abantu bacabange ngayo ukubaluleka kokuhlukahluka kwemvelo nemiphumela yokunyamalala kwayo. Imiphumela ngokuvamile iba mibi impela futhi, ngaphezu kwakho konke, ibe nomthelela kuzinto eziphilayo.
Ukuqothulwa kwezinhlobo zezinto eziphilayo yikhona okudala umthelela kuzinto eziphilayo. Lokhu kungenxa yokwehla kwesilinganiso semvelo. Izinhlobo ezihlukene zakha izixhumanisi ezithile ochungechungeni lokudla ezisebenza ngebhalansi. Uma leyo bhalansi yephuliwe ngoba izinhlobo zilahlekile, zonke ezinye izinhlobo nazo zizothinteka kabi. Kusengathi kuyindida. Uma izingcezu zilahlekile, yonke iphazili ayikwazi ukuqedwa.
Kuyaziwa kubantu abaningi inkinga yamanje esinayo nge izinyosi. Izinyosi zibaluleke kakhulu ezinhlotsheni zezitshalo, ngoba ziyizimpova. Yize kungezona ukuphela kwezinambuzane ezithutha impova ezikhona, zibaluleke kakhulu kuyo yonke imvelo.
Ngakolunye uhlangothi, kukhona nokungalingani emaketangeni e-trophic adala ukuvela kwezinambuzane ezahlukahlukene. Lokhu kwenzeka lapho umhlaseli wezinhlobo ezithile encipha noma enyamalala futhi izinhlobo zezilwane zingakhula ngaphandle kwanoma yiluphi uhlobo lokulawula. Lezi zinambuzane zingadala ukubhujiswa kwezindawo ezinkulu zezitshalo futhi imiphumela yalezi zinambuzane ingaba yimbi kakhulu.
Ukuqothulwa kohlobo oluthile lwesilwane akunaso isisombululo. Ngalesi sizathu, ukusinda komuntu kusongelwa ukunyamalala kwalezi zidalwa eziphilayo. Lokhu kubeka engcupheni impilo yethu nenhlalakahle yethu, ngoba izinto eziningi zemithi zinemvelaphi yemvelo, zombili izilwane nemifino. Ngokulahleka kwezinhlobonhlobo zezinto eziphilayo, izinhlobo zezitshalo ezingaziwa ziyaqedwa, kuvimbela ukwelashwa kwezifo ezahlukahlukene esingenakuzelapha namuhla.
Kakhulu umhlabathi, njengoba amanzi nomoya nakho kuncike enhlotsheni yemvelo yomhlaba. Izimila zibamba iqhaza elibalulekile kulezi zinto zesimo sezulu. Ngenxa yayo, i-CO2 ingangena futhi ingxenye yokushisa egcinwe amagesi abamba ukushisa ingaqedwa.
Njengoba ukwazi ukubona, ukulahleka kwezinhlobonhlobo zezinto eziphilayo kuyinto ekhula kakhulu futhi umonakalo wayo uba nomthelela omkhulu. Angazi ukuthi umuntu uzocabanga nini ngokuthile okuzokulungisa ngempela futhi ayeke ukuganga. Iplanethi ngeke ilinde ukuthi sicabange ngesisombululo, isixazululo kufanele sinikezwe MANJE.
