Mraky dusiv\u00e9ho smogu; pl\u00e1\u017ee pokryt\u00e9 ropou; \u0159eky zbarven\u00e9 do \u010dervena chemik\u00e1liemi. To v\u0161e jsou z\u0159ejm\u00e9 p\u0159\u00edklady zne\u010di\u0161t\u011bn\u00ed.<\/p>\n<\/div>\n

Ne v\u0161echny druhy zne\u010di\u0161t\u011bn\u00ed jsou v\u0161ak snadno viditeln\u00e9. Nap\u0159\u00edklad nad na\u0161imi m\u011bsty a obcemi se mohou vzn\u00e1\u0161et neviditeln\u00e9 oblaky plyn\u016f. Ty mohou zp\u016fsobovat astma a pot\u00ed\u017ee s d\u00fdch\u00e1n\u00edm. Mohou tak\u00e9 zab\u00edjet stromy.<\/p>\n

Dal\u0161\u00edm probl\u00e9mem je zji\u0161t\u011bn\u00ed rozsahu posti\u017een\u00e9 oblasti. V\u00edtr m\u016f\u017ee zne\u010di\u0161\u0165uj\u00edc\u00ed l\u00e1tky rozn\u00e1\u0161et na vzd\u00e1lenost tis\u00edc\u016f kilometr\u016f, z jedn\u00e9 strany oce\u00e1nu na druhou. Chemik\u00e1lie, kter\u00e9 proud\u00ed velk\u00fdmi \u0159ekami, mohou na sv\u00e9 cest\u011b k mo\u0159i zne\u010di\u0161\u0165ovat mnoho zem\u00ed.<\/p>\n

Pak je tu je\u0161t\u011b probl\u00e9m zjistit, kdo za to nese vinu.<\/p>\n

Satelity jsou kl\u00ed\u010dov\u00fdmi n\u00e1stroji v tomto nekone\u010dn\u00e9m boji za \u010distotu na\u0161\u00ed planety. Vesm\u00edrn\u00e9 p\u0159\u00edstroje dok\u00e1\u017eou detekovat \u0161kodliv\u00e9 plyny a chemick\u00fd odpad vypou\u0161t\u011bn\u00fd pr\u016fmyslem, elektr\u00e1rnami a dopravou.<\/p>\n

Satelity dok\u00e1\u017eou p\u0159esn\u011b ur\u010dit zdroje zne\u010di\u0161t\u011bn\u00ed, sledovat jeho pohyb v ovzdu\u0161\u00ed a zjistit, kam se nakonec dostane. Mohou tak\u00e9 zkoumat barvu oce\u00e1nu a detekovat \u00faniky ropy na mo\u0159i, a to jak ve dne, tak v noci.<\/p>\n
