Ekhulwini lamashumi amabili nanye, inkinga yokuphepha kwemvelo iya ngokuqina. Inqubo yokukhiqiza elinganiselayo idinga ukuthi osomabhizinisi banakekele kakhulu ukulahlwa kwemfucuza. Ukulondolozwa kwemvelo kusesimweni esifanele kuyindlela ebalulekile yezenhlalo nezomnotho, ngoba ikhwalithi yempilo yabantu incike ngqo kwikhwalithi yemithombo yemvelo. Ukutholakala kwamanzi okuphuza, ukuzala okukhulu kwenhlabathi, ukusuthiswa kokudla okunamavithamini abalulekile kanye nezinto ezincane, njengoba wazi, ngaphezu komthelela kumuntu wanamuhla, kuthinta impilo yezizukulwane ezizayo.
Izinkinga ezinkulu zemvelo
Izinsizakusebenza zemvelo, ngaphandle kwezindawo ezincane, ziyakwazi ukuthonyelwa abantu nsuku zonke. Isici se-anthropogenic sinikela ekuphazanyisweni kwemijikelezo yemvelo nokuphazamiseka kwamaketanga okunomsoco ngenxa yokuzalaniswa kokufakelwa kwezilwane zasendle ngezinhloso zokuqonda.
Izinkinga ezinkulu zokuphepha kwemvelo ezihambisana nengxenye yomhlabathi zifaka:
- ukugawulwa kwamahlathi nokugawulwa kwamahlathi;
- ukusetshenziswa okungenangqondo kwamadlelo namadlelo;
- ukungabi nenani elifanele lomanyolo;
- ukungabuyisi kwenhlabathi okwanele ngemuva kokuvuna.
Ukuze amasimu akhiqize isivuno esingcono, kuyadingeka ukuthi ukhethe izimo ezifanelekile ngohlobo ngalunye lwesitshalo, utshale inani elanele lezihlahla, futhi wehlise nenani lobuthi obusetshenzisiwe. Njengoba kunzima ukubuyisa ihlathi, kufanelekile ukunakekela ukukhawulela ukugawulwa kwamahlathi asekhona.
Okungabalulekanga kangako namuhla inkinga yokulahlwa kukadoti:
- amabhodlela epulasitiki angenye yezinto ezibhubhisa kakhulu, ngoba azikho izinto ezincane emvelweni ezingadiliza ipulasitiki;
- izikhwama ze-cellophane - eziwela ngaphansi komhlaba, zakha izimo ezungeze izitshalo ezikhona ezingathandeki ekukhuleni kwazo okuqhubekayo;
- amabhethri, okokusebenza kwehhovisi, izingxenye zekhompyutha - ziqukethe ingxenye yamakhemikhali kanye nenkokhiso ethile edinga imizamo eyengeziwe evela kubasebenzi bamabhizinisi azimele.
Ukwakhiwa kwezingxenye zokwenziwa ngumuntu kwakungabonakali kusengaphambili ngokwemvelo. Umuntu kuphela okwazi ukuthola ukulahlwa okwanele kwalowo doti. Isixazululo esifanelekile kungaba ukusebenzisa kabusha ipulasitiki ngemuva kokuyisebenzisa lapho kwenziwa izinto ezintsha ezidingekayo emisebenzini yansuku zonke.
Kepha kuthiwani ngegciwane lomhlaba?
Uma lezi zinkinga ezingenhla zifaka amandla okululama kusuka kumthelela omubi wesikhathi eside emvelweni, khona-ke lezi zindawo ezilandelayo ezibuhlungu emvelweni zingenakuguqulwa.
Ukushintsha ukwakheka kwamakhemikhali e-biosphere kuyinkinga enzima engajwayele ukukhuluma ngayo ngokuzwakalayo:
- Lapho kuba nokuguquka ekuphenduleni kwemvula ohlangothini lwe-asidi, izimvula ezihlinzekelwa ukunisela umhlaba ziba yinto eyinhlekelele. Imvula ene-acid inegalelo elibi kuzo zonke izinto eziphilayo, futhi i-sulfur dioxide eyakhiwe ngophethiloli kawoyela, uwoyela, uphalafini nophethiloli, ngenxa yokwanda kobuthi, yonakalisa kakhulu iplanethi yethu yasekhaya.
- "Umphumela wokushisa okushisayo" uholela ekushiseni kwaminyaka yonke, okuthinta kakhulu izinga lempilo yabantu. Izimbobo ze-ozone ziholela ekukhanyeni kwelanga ngqo ku-biosphere, okucekela phansi kabuhlungu yonke impilo. Emkhathini, inani lesikhutha liyakhuphuka, okufaka isandla ekushiseni kancane kancane komoya.
Iplanethi ithola amanzi amancane futhi asebenzisekayo. Izimo zezulu ziyashintsha, amaphethini wemvelo aya ngokuya ancipha, ukungasebenzi kahle kwenzeka kumaseli ahlukahlukene abaphilayo.
Kuyini ukuphepha kwemvelo
Ukuze usindise iplanethi ethonyeni elilimazayo lezici ezingezinhle, kwaqokelwa lonke igatsha lemvelo. Yonke imibuso inenqubomgomo yokulawulwa kwemfucuza, ukwephulwa kwayo okujeziswa ngumthetho. I-biotechnology yezemvelo ibandakanyeka kakhulu ekuqoqeni, ezokuthutha, ukucubungula kanye nokumaketha. Amalabhorethri ahlakulela zonke izinhlobo zamagciwane angathuthukisa ikhwalithi yemithombo yemvelo. Kwenziwa izinto zokufakelwa ezidiliza ipulasitiki nezinye izinto zokwenziwa. Izingqinamba zenqubomgomo ejwayelekile yezimboni zifaka phakathi izici zobuchwepheshe bokukhiqiza ezizwakala kahle emvelweni okuhloswe ngazo ukuqeda umonakalo kusuka ekwakhiweni kwezinto zokwenziwa.
