Eminyakeni eyizinkulungwane edlule, imisebenzi yabantu ayilimazanga kakhulu imvelo, kepha ngemuva kwezinguquko zobuchwepheshe, ibhalansi phakathi komuntu nemvelo yaphazamiseka, ngoba izinsiza zemvelo sezisetshenziswe kakhulu. Inhlabathi nayo yancipha ngenxa yemisebenzi yezolimo.
Ukucekelwa phansi komhlaba
Ukulima njalo, ukutshala izitshalo kuholela ekonakaleni komhlaba. Umhlabathi ovundile uphenduka ugwadule, okuholela ekufeni kwemiphakathi yabantu. Ukwehla kwenhlabathi kwenzeka kancane kancane futhi izenzo ezilandelayo ziholela kuwo:
- ukuchelela okuningi kunikela ngosawoti womhlabathi;
- ukulahleka kwezinto eziphilayo ngenxa yokungavumelani okwanele;
- ukusetshenziswa ngokweqile kwezibulala-zinambuzane nama-agrochemicals;
- ukusetshenziswa okungenangqondo kwezindawo ezitshaliwe;
- amadlelo angahlelekile;
- ukuguguleka komoya namanzi ngenxa yokugawulwa kwamahlathi.
Umhlabathi uthatha isikhathi eside ukwakheka uphinde ululame kancane. Ezindaweni lapho kudla khona imfuyo, izitshalo zidla zife, namanzi emvula aqeda umhlabathi. Ngenxa yalokho, kungakha imigodi ejulile nemifula. Ukwehlisa ijubane nokumisa le nqubo, kuyadingeka ukuthi uthuthele abantu nezilwane kwezinye izindawo bese utshala ihlathi.
Ukungcoliswa kwenhlabathi
Ngaphezu kwenkinga yokuguguleka nokuqedwa kwezolimo, kunenye futhi inkinga. Lokhu kungcoliswa kwenhlabathi okuvela emithonjeni ehlukahlukene:
- imfucuza yezimboni;
- Ukuchitheka kwemikhiqizo kawoyela;
- umanyolo wezimbiwa;
- ukuthutha imfucuza;
- ukwakhiwa kwemigwaqo, izindawo zokuthutha;
- izinqubo zokuthuthela emadolobheni.
Lokhu nokunye okuningi kuba imbangela yokubhujiswa kwenhlabathi. Uma ungalawuli imisebenzi ye-anthropogenic, khona-ke izindawo eziningi zizophenduka izingwadule nezingwadule. Umhlabathi uzolahlekelwa ukuzala, izitshalo zizofa, izilwane nabantu bazokufa.
