SEJDA: Tak nejaky paralely tam budou. Kurovec, podobne jako ty rasy je pritomny v kazdem zdravem lese. Za normalnich podminek, ale nedochazi k jeho exponencialnimu premnozeni (tzv gradaci). K tomu premnozeni dochazi imho bezne i v prirode, kdyz jsou ruzne naruseny ekosystemovy vazby. Ale tady je to zpusobeny teda zvysenim teploty, ale hlavne tim, ze se splachujou mineralni hnojiva ze zemedelsky produkce, ktery do oceanu dodavaj velky mnozstvi zivin a soucasne jsou vytezovanim naruseny ty casti ekosystemu, ktery se rasama zivi. Imho podobnej problem proste jako mame v nadrzich se sinicema. Celkove tyhle premnozeni jsou problem jako prase, protoze vytvarej mrtvy zony bez kysliku, ktery jsou smrtelny pro zivot. Nektery jsou dnes velky jako cely zeme... Viz treba Mexickej zaliv, kam usti splasky hnojiv z US zemedelsky produkce.
Ale fuckup je to treba i v Baltskym mori, checkuj sateltni snimky ras:
Less oxygen dissolved in the water is often referred to as a “dead zone” because most marine life either dies, or, if they are mobile such as fish, leave the area. Habitats that would normally be teeming with life become, essentially, biological deserts.
Hypoxic zones can occur naturally, but scientists are concerned about the areas created or enhanced by human activity. There are many physical, chemical, and biological factors that combine to create dead zones, but nutrient pollution is the primary cause of those zones created by humans. Excess nutrients that run off land or are piped as wastewater into rivers and coasts can stimulate an overgrowth of algae, which then sinks and decomposes in the water. The decomposition process consumes oxygen and depletes the supply available to healthy marine life.
Dead zones occur in coastal areas around the nation and in the Great Lakes — no part of the country or the world is immune. The second largest dead zone in the world is located in the U.S., in the northern Gulf of Mexico.
