Un studiu recent, publicat \u00een revista \u0219tiin\u021bific\u0103 The Lancet Planetary Health, dedicat\u0103 rela\u021biei dintre mediu, clim\u0103 \u0219i s\u0103n\u0103tate, dezv\u0103luie c\u0103, dac\u0103 produc\u021bia mondial\u0103 de plastic continu\u0103 \u00een ritmul actual, costurile pentru s\u0103n\u0103tatea popula\u021biei globale vor cre\u0219te dramatic p\u00e2n\u0103 \u00een anul 2040.<\/p>\n

Cercetarea, prezentat\u0103 de Futura-Sciences<\/a>, porne\u0219te de la cantitatea de plastic produs\u0103 la nivel mondial: peste 400 de milioane de tone sunt fabricate anual. Din acestea, aproape dou\u0103 treimi ajung, mai devreme sau mai t\u00e2rziu, la gunoi, \u00een sistemele de colectare ale ora\u0219elor \u0219i comunelor.<\/p>\n

Surs\u0103 constant\u0103 de poluare<\/h2>\n

Odat\u0103 ajuns acolo, plasticul nu dispare. Dimpotriv\u0103, pe tot parcursul ciclului s\u0103u de via\u021b\u0103 \u2013 de la extrac\u021bia petrolului \u0219i gazelor folosite ca materie prim\u0103, la produc\u021bie, transport, reciclare sau incinerare \u2013 el genereaz\u0103 emisii de gaze cu efect de ser\u0103, contribuie la poluarea aerului \u0219i elibereaz\u0103 substan\u021be chimice toxice, cu efecte directe asupra s\u0103n\u0103t\u0103\u021bii.<\/p>\n

Autorii studiului, cercet\u0103tori din Marea Britanie \u0219i Fran\u021ba, au folosit modele statistice pentru a estima impactul cumulativ al acestor procese. Echipa include speciali\u0219ti de la London School of Hygiene & Tropical Medicine, una dintre cele mai importante institu\u021bii de cercetare \u00een s\u0103n\u0103tate public\u0103 din Regatul Unit, precum \u0219i de la Institut national de la recherche agronomique \u2013 institut public francez care studiaz\u0103 agricultura, alimenta\u021bia \u0219i mediul.<\/p>\n

Pre\u021bul s\u0103n\u0103t\u0103\u021bii p\u00e2n\u0103 \u00een 2040<\/h2>\n

Rezultatele sunt \u00eengrijor\u0103toare. Dac\u0103 modul actual de producere \u0219i gestionare a plasticului r\u0103m\u00e2ne neschimbat \u2013 scenariul \u201ebusiness as usual\u201d \u2013 impactul asupra s\u0103n\u0103t\u0103\u021bii la nivel mondial ar putea ajunge la 83 de milioane de ani de via\u021b\u0103 pierdu\u021bi p\u00e2n\u0103 \u00een 2040.<\/p>\n

Practic, raportat la anul de referin\u021b\u0103 2016, impactul aproape s-ar dubla, de la aproximativ 2,1 milioane de ani de via\u021b\u0103 pierdu\u021bi la 4,5 milioane.<\/p>\n

Un impact mai mare dec\u00e2t se credea<\/h2>\n

\u201ePoluarea cu plastic \u0219i emisiile asociate ciclului s\u0103u de via\u021b\u0103 afecteaz\u0103 via\u021ba \u0219i bun\u0103starea popula\u021biilor din \u00eentreaga lume, dar amploarea acestor efecte asupra s\u0103n\u0103t\u0103\u021bii nu a fost \u00eenc\u0103 pe deplin cuantificat\u0103\u201d, explic\u0103 cercet\u0103torii.<\/p>\n

Potrivit acestora, efectele asupra s\u0103n\u0103t\u0103\u021bii sunt legate de \u00eenc\u0103lzirea global\u0103, poluarea aerului \u0219i de apari\u021bia bolilor, inclusiv a unor decese premature, cauzate de expunerea la substan\u021be chimice toxice.<\/p>\n

Ciclul unei sticle de plastic<\/h2>\n

Pentru a face mai u\u0219or de \u00een\u021beles acest mecanism, una dintre autoarele studiului, Megan Deeney, ofer\u0103 exemplul unei simple sticle de ap\u0103. Aceasta este fabricat\u0103 din petrol \u0219i gaze fosile, transformate \u00een polietilen tereftalat (PET) \u0219i transportat\u0103 pe distan\u021be lungi p\u00e2n\u0103 la consumator. Dup\u0103 utilizare, chiar \u0219i \u00een condi\u021biile recicl\u0103rii, are \u0219anse mari s\u0103 ajung\u0103 \u00eentr-o groap\u0103 de gunoi. Acolo, \u00een timp, se descompune \u0219i elibereaz\u0103 substan\u021be chimice \u00een mediul \u00eenconjur\u0103tor.<\/p>\n

Efecte care nu au fost m\u0103surate<\/h2>\n

Cercet\u0103torii atrag aten\u021bia c\u0103 studiul nu surprinde pe deplin amploarea riscurilor. Analiza nu include expunerea direct\u0103 a popula\u021biei la substan\u021bele care pot migra din ambalajele alimentare \u2013 precum microplasticele sau al\u021bi compu\u0219i chimici \u2013 ceea ce \u00eenseamn\u0103 c\u0103 impactul real asupra s\u0103n\u0103t\u0103\u021bii ar putea fi chiar mai mare dec\u00e2t cel estimat.<\/p>\n

Solu\u021bia: mai pu\u021bin plastic<\/h2>\n

Exist\u0103 \u00eens\u0103 \u0219i ve\u0219ti mai pu\u021bin sumbre. Modelele arat\u0103 c\u0103 impactul asupra s\u0103n\u0103t\u0103\u021bii ar putea fi redus cu aproximativ 43% p\u00e2n\u0103 \u00een 2040, dac\u0103 statele ar adopta politici ferme: reducerea produc\u021biei de plastic, \u00eembun\u0103t\u0103\u021birea colect\u0103rii \u0219i elimin\u0103rii de\u0219eurilor, cre\u0219terea recicl\u0103rii, \u00eenlocuirea unor produse din plastic cu materiale alternative \u0219i introducerea sistemelor de reutilizare.<\/p>\n

\u00cens\u0103 cea mai eficient\u0103 m\u0103sur\u0103 r\u0103m\u00e2ne reducerea produc\u021biei de plastic \u00een sine, chiar \u0219i f\u0103r\u0103 substituirea imediat\u0103 a materialelor, atrag aten\u021bia speciali\u0219tii. Un acord \u00een acest sens la nivel mondial nu a fost posibil p\u00e2n\u0103 acum, \u00een principal din cauza intereselor economice ale statelor produc\u0103toare de petrol. \u201e\u00cen fa\u021ba unei crize de s\u0103n\u0103tate public\u0103 la scar\u0103 mondial\u0103, nimic nu \u00eempiedic\u0103 \u00eens\u0103 \u021b\u0103rile s\u0103 ac\u021bioneze la nivel na\u021bional\u201d, consider\u0103 cercet\u0103torii.<\/p>\n","protected":false},"excerpt":{"rendered":"
