Vand er afg\u00f8rende for livet, og derfor er det vigtigt, at vi passer godt p\u00e5 vores have, floder og s\u00f8er.<\/p>\n<\/div>\n<p>For at hj\u00e6lpe med dette har ESA sendt rumfart\u00f8jer som Sentinel-satellitterne i kredsl\u00f8b om Jorden. De er udviklet til at overv\u00e5ge Jorden fra rummet og sende billeder til forskerne p\u00e5 Jorden. De oplysninger, de indsamler, bruges til at overv\u00e5ge vandstandene, planl\u00e6gge foranstaltninger mod oversv\u00f8mmelser og sikre, at der er vand nok til alle.<\/p>\n<p>Nu bliver vi mere og mere opm\u00e6rksomme p\u00e5 et stort problem, som vores have st\u00e5r over for: plastforurening. Hvert \u00e5r ender omkring 10 millioner ton plastaffald i Jordens have. Det er let at se plastaffald, n\u00e5r det skylles op p\u00e5 strandene, men affaldet findes ogs\u00e5 langt ude p\u00e5 havet. Nogle steder er der endda fundet plast i den frosne polaris!<\/p>\n<\/p>\n<p>L\u00e6s mere om, hvordan ESA\u2019s satellitter bidrager til forvaltningen af vandforsyningen. Ophavsret: EO4SD-Water-konsortiet.<\/p>\n<p>Plasten i vores have nedbrydes gradvist af b\u00f8lgerne. Den kan derefter ved et uheld blive spist af fisk og andre havdyr. Ud over at v\u00e6re skadelig for disse dyr, kommer plasten ind i f\u00f8dek\u00e6den, hvilket betyder, at andre levende v\u00e6sener \u2013 herunder mennesker \u2013 p\u00e5virkes.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"ESA - ScienceOffice.org\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2018\/04\/Remote_sensing_of_marine_plastic_litter\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2018\/04\/remote_sensing_of_marine_plastic_litter\/17873039-2-eng-GB\/Remote_sensing_of_marine_plastic_litter.jpg\" alt=\"Remote sensing of marine plastic litter\"><figcaption>Fjernm\u00e5ling af plastikaffald i havet<\/figcaption><\/figure>\n<p>Satellitkort over havstr\u00f8mme bruges allerede til at forudsige, hvor affald vil samle sig i Stillehavet, Atlanterhavet og Det Indiske Ocean. Forskerne h\u00e5ber at tage dette et skridt videre ved at unders\u00f8ge, om satellitter direkte kan p\u00e5vise plastforurening, der flyder i Jordens have. ESA-satellitter vil fors\u00f8ge at g\u00f8re dette ved at studere det infrar\u00f8de lys, der reflekteres af affaldet, og lede efter et s\u00e6rligt \u201cfingeraftryk\u201d, der viser, at der er plast til stede. Denne teknologi bruges allerede i genvindingsanl\u00e6g til at sortere forskellige plasttyper fra hinanden.<\/p>\n<p>Hvis det her fungerer godt, kan vi udarbejde et pr\u00e6cist kort over Jordens have, der viser, hvor plastikaffaldet flyder. N\u00e5r vi f\u00f8rst kender problemets reelle omfang, kan vi udarbejde de bedste l\u00f8sninger p\u00e5 det!<\/p>\n<p>Sjovt faktum:<\/p>\n<p>Sentinel-satellitterne har f\u00e5et deres navn efter soldater, hvis opgave det er at holde \u00f8je med farer.
