D\u00edky sv\u00fdm n\u00e1dhern\u00fdm modr\u00fdm oce\u00e1n\u016fm nen\u00ed divu, \u017ee se Zemi \u0159\u00edk\u00e1 Modr\u00e1 planeta. Voda je nezbytn\u00e1 pro \u017eivot, a proto je d\u016fle\u017eit\u00e9, abychom se dob\u0159e starali o na\u0161e mo\u0159e, oce\u00e1ny, \u0159eky a jezera.<\/p>\n<\/div>\n

Aby v tomto ohledu pomohla, vyslala ESA na ob\u011b\u017enou dr\u00e1hu kolem Zem\u011b dru\u017eice, jako jsou nap\u0159\u00edklad Sentinel. Jsou navr\u017eeny tak, aby pozorovaly Zemi z vesm\u00edru a zas\u00edlaly sn\u00edmky v\u011bdc\u016fm na Zemi. Informace, kter\u00e9 shroma\u017e\u010fuj\u00ed, se vyu\u017e\u00edvaj\u00ed ke sledov\u00e1n\u00ed hladin vody, k p\u0159\u00edprav\u00e1m na povodn\u011b a k zaji\u0161t\u011bn\u00ed toho, aby bylo dostatek vody pro v\u0161echny.<\/p>\n

V sou\u010dasn\u00e9 dob\u011b si st\u00e1le v\u00edce uv\u011bdomujeme velk\u00fd probl\u00e9m, s n\u00edm\u017e se pot\u00fdkaj\u00ed na\u0161e oce\u00e1ny: zne\u010di\u0161t\u011bn\u00ed plasty. Ka\u017ed\u00fd rok se do sv\u011btov\u00fdch oce\u00e1n\u016f vyhod\u00ed p\u0159ibli\u017en\u011b 10 milion\u016f tun plastov\u00e9ho odpadu. Plastov\u00fd odpad je snadno viditeln\u00fd, kdy\u017e ho vlny vyvrhuj\u00ed na pl\u00e1\u017ee, ale odpadky se nach\u00e1zej\u00ed i daleko na mo\u0159i. N\u011bkter\u00e9 z nich byly dokonce objeveny v zamrzl\u00e9m pol\u00e1rn\u00edm ledu!<\/p>\n<\/p>\n

Plasty v na\u0161ich oce\u00e1nech se pod vlivem vln postupn\u011b rozpadaj\u00ed. Ryby a dal\u0161\u00ed mo\u0159\u0161t\u00ed \u017eivo\u010dichov\u00e9 je pak mohou omylem spolknout. Plast je nejen \u0161kodliv\u00fd pro tato zv\u00ed\u0159ata, ale dost\u00e1v\u00e1 se tak\u00e9 do potravinov\u00e9ho \u0159et\u011bzce, co\u017e znamen\u00e1, \u017ee m\u00e1 dopad i na dal\u0161\u00ed \u017eiv\u00e9 organismy \u2013 v\u010detn\u011b lid\u00ed.<\/p>\n

Satelitn\u00ed mapy oce\u00e1nsk\u00fdch proud\u016f se ji\u017e vyu\u017e\u00edvaj\u00ed k p\u0159edpov\u00edd\u00e1n\u00ed m\u00edst, kde se bude hromadit odpad v Tich\u00e9m, Atlantsk\u00e9m a Indick\u00e9m oce\u00e1nu. V\u011bdci doufaj\u00ed, \u017ee v tomto sm\u011bru postoup\u00ed je\u0161t\u011b o krok d\u00e1l a ov\u011b\u0159\u00ed, zda satelity dok\u00e1\u017eou p\u0159\u00edmo detekovat plastov\u00e9 zne\u010di\u0161t\u011bn\u00ed plovouc\u00ed v mo\u0159\u00edch Zem\u011b. Satelity ESA by se o to pokusily t\u00edm, \u017ee by studovaly infra\u010derven\u00e9 z\u00e1\u0159en\u00ed odra\u017een\u00e9 od odpadk\u016f a hledaly by speci\u00e1ln\u00ed \u201cotisk\u201d, kter\u00fd by nazna\u010doval p\u0159\u00edtomnost plastu.

Pokud to bude fungovat, budeme moci vytvo\u0159it p\u0159esnou mapu sv\u011btov\u00fdch oce\u00e1n\u016f, na kter\u00e9 bude vid\u011bt, kde se vzn\u00e1\u0161\u00ed plastov\u00fd odpad.
