<\/div>[vc_column_text css_animation=”fadeIn”]Broj stanovnika na Zemlji 1900. godine, dakle prije svega 120 godina iznosio je 1,65 milijardi, a procjena je da \u0107e do kraja ovog stolje\u0107a narasti na oko 11 milijardi. Uz ovakvo drasti\u010dno pove\u0107anje broja ljudi, tako\u0111er je do\u0161lo i do drasti\u010dnih promjena u stilu \u017eivota. Danas gotovo svako ku\u0107anstvo posjeduje barem jedan automobil, nekoliko mobitela i brojne ku\u0107anske ure\u0111aje pa je tzv. \u201ekonzumeristi\u010dki\u201c stil \u017eivota doveo do toga da je pritisak na prirodu pove\u0107an znatno vi\u0161e od 10 puta u svega stotinjak godina. Trenuta\u010dno stanje je takvo da bi trebali 1,8 kapaciteta Zemlje da osiguramo odr\u017eivost resursa i usluga ekosustava koje upotrebljavamo.[\/vc_column_text][vc_column_text css_animation=”fadeIn”]<\/p>\n

Ugro\u017eavanjem prirode ugro\u017eavamo i usluge ekosustava koje nam ona pru\u017ea, a samim time i kvalitetu vlastitih \u017eivota. Preko 25% vrsta je ugro\u017eeno te im prijeti visok rizik od izumiranja, a u posljednjih 50 godina brojnost populacija u prosjeku je smanjena za 20%.<\/strong><\/h2>\n

[\/vc_column_text][vc_column_text css_animation=”fadeIn”]Biomasa divljih kralje\u017enjaka smanjena je za 82%, stani\u0161ta vrsta naru\u0161ena su za 30%, gotovo pola milijuna vrsta nema adekvatnu povr\u0161inu stani\u0161ta. Podaci su to Globalne procjene stanja bioraznolikosti i usluga ekosustava<\/a> (eng. Global assessment report on biodiversity and ecosystem services, IPBES, 2019) u kojoj je sudjelovalo 145 znanstvenika iz 50 zemalja, a u sklopu koje je izra\u0111ena procjena stanja za ukupno 132 zemlje \u010dlanice. U obzir su uzeti podaci koji su dostupni za posljednjih 50 godina.<\/p>\n

Postoje brojne studije koje upu\u0107uju na sli\u010dne zaklju\u010dke pa tako npr. Izvje\u0161\u0107e o \u017eivotu na planeti (eng. \u201eLiving Planet Report\u201c, WWF, 2020<\/a> ) upozorava da je izgubljeno 90% mo\u010dvara, a da su se veli\u010dine populacija smanjile za 84% kod slatkovodnih organizama, a za 68% kod pra\u0107enih vrsta sisavaca, ptica, riba, gmazova i vodozemaca (obuhva\u0107eno 21.000 vrsta). Divlji opra\u0161iva\u010di su tako\u0111er veoma ugro\u017eeni, a o njima direktno ovisi proizvodnja hrane za \u010dovje\u010danstvo i divlje vrste. Procijenjeno je da koristimo barem 58% resursa vi\u0161e nego \u0161to to granica odr\u017eivosti dozvoljava.[\/vc_column_text][vc_column_text css_animation=”fadeIn”]<\/p>\n

Glavni razlozi gubitka bioraznolikosti su:<\/strong><\/h2>\n
    \n
  • Direktno uni\u0161tavanje stani\u0161ta<\/strong><\/li>\n
  • Invazivne strane vrste<\/strong><\/li>\n
  • Zaga\u0111enje<\/strong><\/li>\n
  • Neodr\u017eivo kori\u0161tenje resursa<\/strong><\/li>\n
  • Klimatske promjene<\/strong><\/li>\n<\/ul>\n

    [\/vc_column_text][vc_column_text css_animation=”fadeIn”]Treba uzeti u obzir da se prema najnovijim podacima trenutno u upotrebi nalazi oko 350.000 vrsta razli\u010ditih kemikalija. Utjecaj na okoli\u0161 ispitan je za manje od 1% njih. Praksa pokazuje da se o negativnim posljedicama nekih od njih mo\u017ee saznati tek kroz razdoblje od 50 i vi\u0161e godina kori\u0161tenja kada postaje jasno da su neke bolesti bile uzrokovane utjecajem jedne ili vi\u0161e kemikalija kombinirano.<\/p>\n

    Za\u0161tita prirode nikada nije bila potrebnija. U Hrvatskoj se prirodu \u0161titi na vi\u0161estruke na\u010dine, a glavni mehanizmi su upravljanje za\u0161ti\u0107enim podru\u010djima i podru\u010djima ekolo\u0161ke mre\u017ee Natura 2000, razli\u010dite vrste procjene utjecaja zahvata na okoli\u0161 i prirodu te progla\u0161avanjem vrsta, minerala i fosila za\u0161ti\u0107enima. Temeljni dokument za\u0161tite prirode u Hrvatskoj je Zakon o za\u0161titi prirode.[\/vc_column_text][vc_btn title=”Vi\u0161e o upravljanju za\u0161ti\u0107enim podru\u010djima” shape=”square” color=”default” size=”lg” align=”center” css_animation=”fadeIn” link=”url:https%3A%2F%2Fzeleni-prsten.hr%2Fportal%2Fzastita-prirode%2Fupravljanje%2F|title:Upravljanje||” el_class=”btn-outline text-black”][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
