Ukuthetha ngolwandle, abantu abaninzi bacinga ngamanzi aluhlaza okwesibhakabhaka, iilwandle zegolide, kunye nezidalwa zolwandle ezithandekayo ezingenakubalwa.Kodwa ukuba unethuba lokuya kwisiganeko sokucoca ulwandle, unokumangaliswa yimeko yolwandle olusondeleyo.
Ngomhla wama-2018 weZizwe eziManyeneyo wokuCoceka koLwandle, imibutho yokusingqongileyo elwandle kwilizwe lonke yacoca iikhilomitha ezingama-64.5 kunxweme kwiidolophu ezingama-26 eziselunxwemeni, ivuna ngaphezulu kweetoni ezili-100 zenkunkuma, elingana namahlengesi angama-660 eentlanzi zabantu abadala, ngeplastiki elahliweyo edlula i-84% yenkunkuma iyonke.
Ulwandle ngumthombo wobomi eMhlabeni, kodwa ngaphezu kwezigidi ezisi-8 zeetoni zeplastiki zigalelwa elwandle minyaka le.Amashumi alithoba ekhulwini eentaka zaselwandle ziye zatya inkunkuma yeplastiki, kwaye iminenga emikhulu ivala inkqubo yazo yokwetyisa, kwaye—— Mariana Trench , eyona ndawo inzulu kwiplanethi, inamasuntswana eplastiki.Ngaphandle kwesenzo, kuya kubakho inkunkuma yeplastiki eninzi elwandle kuneentlanzi ngo-2050.
Ulwandle lweplastiki alukwazi nje ukusongela ukusinda kobomi baseLwandle, kodwa lulimaza impilo yabantu ngokusebenzisa ikhonkco lokutya.Uphononongo lwezonyango lwakutsha nje luchaze ukuba ukuya kuthi ga kwi-microplastics esithoba yafunyanwa kwilindle lomntu okokuqala.I-microplastics encinci ingangena egazini, inkqubo ye-lymphatic kunye nesibindi, kunye ne-microplastics emathunjini inokuchaphazela impendulo yokuzivikela kwi-digestive system.
“Ukunciphisa ungcoliseko lweplastiki kunxulumene nekamva lethu ngamnye wethu,” wacebisa uLiu Yonglong, umlawuli weZiko loPhuhliso lweNtlalontle yoLuntu lwaseShanghai Rendo Marine."Okokuqala, kufuneka sinciphise ukusetyenziswa kweemveliso zeplastiki. Xa kufuneka sizisebenzise, ukuhlaziya kwakhona sisisombululo esisebenzayo."
Iplastiki ibe yinkunkuma ibe bubuncwane, ukwenziwa kwezinto zemoto
UZhou Chang, injineli kwiZiko le-Ford Nanjing R & D, uye wanikela iqela lakhe kule minyaka mithandathu idlulileyo ekufundeni izinto ezizinzileyo, ngakumbi iplastiki esetyenzisiweyo, ukwenza iindawo zemoto.
Umzekelo, iibhotile zamanzi eeminerali ezisetyenzisiweyo, zinokuhlelwa, zicocwe, zityunyuzwe, zinyibilike, zibe yigranular, zilukwe kwilaphu lesitulo semoto, iirola ezilahliweyo zoomatshini bokuhlamba, zisetyenzwe zibe yipleyiti eqinileyo neyomeleleyo esezantsi kunye nephakeji yehabhu;ifayibha yeplastiki kwikhaphethi endala inokucutshungulwa kwisakhelo sekhonsoli eseziko kunye nesibiyeli sepleyiti yesikhokelo esingasemva;Izinto ezinkulu zokupakisha zeplastiki, ezisetyenziselwa ukucubungula isiseko somnyango, kunye neekona zelaphu le-airbag ngexesha lenkqubo yokuvelisa ukwenza i-skeleton egcwele amagwebu njengekholamu.
Umgangatho ophezulu wolawulo, ukwenzela ukuba ukuphinda kusetyenziswe iplastiki kukhuselekile kwaye kucocekile
"Abathengi banokuxhalaba malunga nokuphinda kusetyenziswe iplastiki engakhuselekanga, umgangatho awuqinisekiswanga, senze iseti yendlela yolawulo olupheleleyo, inokuba luvavanyo olungqongqo kunye nolawulo lomgangatho, ukuqinisekisa ukuba iindawo zokuvelisa izinto ezihlaziyiweyo zinokudlula umaleko phezu kongqinisiso, ukuhlangabezana ngokupheleleyo nehlabathi jikelele le-ford. umgangatho," wazisa uZhou Chang.
Umzekelo, izinto eziluhlaza ziya kucocwa kwaye ziphathwe kwiqondo lokushisa eliphezulu, kunye nelaphu lesihlalo kunye nezinye iimveliso ziya kuvavanywa ukungunda kunye nokwaliwa ukuqinisekisa ucoceko kunye nokhuseleko lokusetyenziswa kwezinto ezihlaziyiweyo.
"Okwangoku, ukusebenzisa iplastiki ehlaziyiweyo ukwenza iinxalenye zemoto akuthethi ukuba iindleko zokuvelisa eziphantsi," uZhou wachaza, "kuba ukuthandwa kwezi zicelo zendalo kwishishini kufuneka kuphuculwe. inokuncitshiswa ngakumbi.”
Kule minyaka mithandathu idlulileyo, abakwaFord baphuhlise ngaphezu kweshumi elinambini ababoneleli bezinto ezisetyenzisiweyo e-China, kwaye baphuhlise iilebhile zemathiriyeli ezikumgangatho ophezulu zokurisayikilisha.Ngo-2017, iFord yaseChina iye yaphinda yarisayikilishe ngaphezulu kweetoni eziyi-1,500 zemathiriyeli.
"Ukunciphisa ungcoliseko lweplastiki kunye nokukhusela okusingqongileyo kunye neentlobo-ntlobo zezinto eziphilayo azikho i-icing kwikhekhe, kodwa yinto ekufuneka siyithathele ingqalelo kwaye siyisombulule ngokupheleleyo," watsho uZhou Chang."Ndiyathemba ukuba iinkampani ezininzi zinokujoyina ukhuseleko lokusingqongileyo kwaye ziguqule inkunkuma ibe bubutyebi kunye."
