Biologisk mangfold<\/h1>\n\n\n

Verdien av biologisk mangfold<\/h2>\n\t

Hvorfor er det s\u00e5 viktig \u00e5 bevare mangfoldet som finnes i naturen? At alle organismer har en \u00f8kologisk rolle blir mer og mer forst\u00e5tt. Det finnes ogs\u00e5 gode etiske argumenter for ikke \u00e5 utrydde arter. Den estetiske verdien av intakt natur er \u00e5penbar, selv om de f\u00e6rreste legger merke til om en sjelden plante- eller dyreart forsvinner. Men hva med den \u00f8konomiske verdien av det biologiske mangfoldet?<\/p>\n\t\t

Naturvernforbundet i Halden arrangerte \u00e5rsm\u00f8te torsdag 12. mars med rundt 30 deltakere, og det var unison tilbakemelding fra medlemmene om at vi i Halden kommune m\u00e5 prioritere motstand mot vindkraftanlegg i Ankerfjella.

En slik nedbygging av natur vil v\u00e6re dramatisk for Halden<\/p>\n\t\t
