Amachibi namachibi ezweni lonke ahlupheke ngenxa yokulahlwa kwendle nokulahlwa kwendle, okuwumphumela wazo zombili izindawo zokuhlala kanye nemisebenzi yezimboni. Lobu budedengu budale umonakalo omkhulu emizimbeni yethu yasemanzini ahlanzekile, kungcolisa amanzi futhi kucekele phansi impilo yasemanzini. Ukwelashwa kwamakhemikhali okuvamile, nakuba ngezinye izikhathi kusebenza ngempumelelo, ngokuvamile kuza nemiphumela emibi engahlosiwe futhi yehluleka ukunikeza izixazululo zesikhathi eside.
NgokweZizwe Ezihlangene, cishe izindawo ezisogwini ezingu-400 kanye namachibi anamanzi ahlanzekile angaphezu kuka-100 ahlushwa I-Harmful Algal Blooms (HABs), ebangela ukucekelwa phansi kwemvelo okusakazekile, ukulahleka kwezinhlobonhlobo zezinto eziphilayo, futhi kubeka engcupheni impilo yabantu. Ngaphezu kwalokho, umbiko we-European Environment Agency wembula ukuthi amachibi angaphezu kuka-60% aseYurophu abhekene nosongo olubangelwa izingcindezi ezihlobene nokufudukela emadolobheni.
Imizamo yokulungisa ibalulekile ekuvikeleni nasekubuyiseleni imvelo ehlukahlukene, ukuqinisekisa ukusinda kwezinhlobonhlobo zezitshalo nezilwane, kanye namagciwane. Lokhu kukhuthaza ukulinganisela okuphelele kwemvelo futhi kugcine izindawo zokuhlala ezibucayi.
Ukulungiswa kuqinisekisa ukutholakala kwemithombo yamanzi ahlanzekile naphephile, okuzuzisa kokubili imiphakathi yabantu kanye nezilwane zasendle. Ivikela imithombo yamanzi okuphuza futhi inciphise nengozi yezifo ezibangelwa amanzi.
Amachibi avuselelwe kabusha namachibi anikeza amathuba emisebenzi yokuzijabulisa ethuthukisiwe njengokubhukuda, ukuhamba ngesikebhe, nokudoba. Lokhu kusekela ukuzijabulisa kwangaphandle, kuthuthukisa ezokuvakasha, futhi kukhuthaze umnotho wendawo.
Ngokuvuselela imithombo yamanzi, sibamba iqhaza ngenkuthalo ekongiweni kwemithombo yemvelo, siqinisekisa ukusetshenziswa kwayo ngokuqhubekayo ezizukulwaneni ezizayo.
Amachibi anempilo namachibi adlala indima ebalulekile ekulawuleni isimo sezulu ngokumunca nokusabalalisa amandla elanga. Lokhu kusiza ukuzinzisa amazinga okushisa embulunga yonke kanye nezimo zesimo sezulu, kube nomthelela ekuqiniseni isimo sezulu.
Uma kucatshangelwa lezi zici ezibalulekile, kusobala ukuthi ukulungisa amachibi namachibi kubalulekile ekulondolozeni nasekubuyiseleni le mithombo yamanzi ahlanzekile ebalulekile.
I-organic matter eyeqile, udaka nodaka, ukudumba, nokungalingani kwezakhi okubangela i-eutrophication
Izinto eziphilayo ngokweqile, udaka nodaka, ukungcola, ukungalingani kwezakhi eziholela eutrophication, izindawo ezifile ngenxa yokuntuleka kwegazi, nokufa kwezinhlanzi okubangelwa amazinga aphezulu e-ammonia.
Ukunikeza izixazululo eziklanyelwe izindaba ezinjengokuchitheka kukawoyela, ukulungiswa kwe-nallah (umsele wokudonsa amanzi), kanye nokuphathwa kwechibi.
