Ukufunda ngoLwandle

Ndikhethe ukufunda e-Ocean Foundation kuba bendisazi kancinci malunga nolwandle kunye neengenelo zalo ezininzi. Ndandisazi ngokubanzi ukubaluleka kweelwandle kwi-ikhosistim yethu kunye norhwebo lwehlabathi. Kodwa, bendisazi kancinci kakhulu malunga nendlela izinto ezenziwa ngabantu ezizichaphazela ngayo iilwandle. Ngexesha lam e-TOF, ndafunda malunga nemiba emininzi ebandakanya ulwandle, kunye nemibutho eyahlukeneyo ezama ukunceda.

I-Acidification yoLwandle kunye noNgcoliseko lwePlastiki

Ndafunda ngeengozi ze Ulwabiwo olwandle (OA), ingxaki eye yakhula ngokukhawuleza ukususela kwinguqulelo yezoshishino. I-OA ibangelwa ziimolekyuli zekharbon diokside ezinyibilikayo elwandle, nto leyo ekhokelela ekuyilweni kweasidi eyingozi kubomi baselwandle. Lo mkhwa ubangele umonakalo omkhulu kwiiwebhu zokutya zaselwandle kunye nokubonelela ngeeprotheyini. Ndaye ndangenela inkomfa apho uTom Udall, uSenator ophezulu waseNew Mexico, wathi thaca eyakhe Yahlukana nePlastiki yoNgcoliseko Act. Lo mthetho unokuvala izinto zeplastiki ezisetyenziswa kanye kuphela ezingaphinde zisetyenziswe kwaye zenze abavelisi bezikhongozeli zokupakisha bayile, balawule, kwaye baxhase ngemali inkunkuma kunye neenkqubo zokurisayikilishwa.

Umdla ngekamva loLwandle

Eyona nto bendiyonwabela kakhulu ngamava am kukwazi abantu abanikezela imisebenzi yabo ukusebenzela ikamva elizinzileyo lolwandle. Ukongezelela ekufundeni ngeembopheleleko zabo zobungcali nokuba zazinjani iintsuku zabo eofisini, ndafumana ithuba lokufunda ngeendlela ezibakhokelela kwimisebenzi yokulondoloza ulwandle.

Izoyikiso kunye noKwazisa

Ulwandle lujongene nezoyikiso ezininzi ezinxulumene nabantu. Ezi zoyikiso ziya kuba mbi ngakumbi xa kujongwe ukukhula kwabemi kunye nophuhliso lwemizi-mveliso. Ezinye zezi zoyikiso ziquka ukwenziwa kweasidi yolwandle, ungcoliseko lweplastiki, okanye ilahleko yemithi yemango kunye nengca yolwandle. Nangona kunjalo, kukho umba omnye okhoyo ongonakalisi ngokuthe ngqo ulwandle. Lo mba kukungaqondi ukuba kuqhubeka ntoni na ngeelwandle zethu.

Malunga neshumi leepesenti labantu abaxhomekeke elwandle njengomthombo wesondlo ozinzileyo – oko kumalunga nama-870 ezigidi zabantu. Sikwaxhomekeke kuyo ngezinto ezahlukahlukeneyo ezinjengamayeza, ukulawulwa kwemozulu, kwanokuzonwabisa. Nangona kunjalo, ababaninzi abantu abakwaziyo oku kuba abachatshazelwa ngokuthe ngqo kwiinzuzo zayo ezininzi. Oku kungazi, ndiyakholelwa, kuyonakalisa ulwandle lwethu njengayo nayiphi na enye ingxaki efana ne-asidi yolwandle okanye ungcoliseko.

Ngaphandle kolwazi ngeenzuzo zolwandle lwethu, asiyi kukwazi ukutshintsha imiba ejongene nolwandle lwethu. Ukuhlala e-DC, asizixabisi ngokupheleleyo iingenelo ezisinikwa lulwandle. Thina, abanye ngaphezu kwabanye, sixhomekeke elwandle. Kodwa ngelishwa, ekubeni ulwandle alukho emva kwendlu yethu, siyalibala malunga nokuphila kwalo. Asiluboni ulwandle kubomi bethu bemihla ngemihla, ngoko ke asicingi ukuba ludlala indima ebonakalayo kulo. Ngenxa yoku, siyalibala ukuthatha inyathelo. Siyalibala ukucinga phambi kokuba sithathe isixhobo esilahlwayo kwindawo yokutyela esiyithandayo. Siyalibala ukuphinda sisebenzise okanye siphinde sisebenzise izikhongozeli zethu zeplastiki. Kwaye ekugqibeleni, sigqibela ngokungazi ukuba bonakalise ulwandle ngokungazi.
