Biologen lassen Blumen aus der Eiszeit blühen

Wie will man diese Wüsten bewässern und graslandschaften wachsen lassen? Was hat der mensch für einen nutzen (finanziell denn darum geht es immer) wenn er erstmal Millionen im jahr ausgeben muss um am Ende weniger dabei rauszubekommen?

Du kannst es drehen und wenden wie Du willst. Es kann nicht funktionieren.

Erkundige dich mal etwas, es gab schon pilotprojekte in diese richtung mit künstlichen atmosphären.
Bewässerung,bewuchs.....alles intern geregelt.

Das mag ja auch alles sein und ich würde es ja toll finden wenn das klappen würde ohne das die Tiere darunter zu leiden haben, aber ich kanns mir beim besten willen nicht vorstellen.

Ich hoffe die Notwendigen Gelder werden bewilligt & alle Notwendigkeiten getroffen, ist ja schon i-wie eine interessante Sache :)

Abstract

Whole, fertile plants of Silene stenophylla Ledeb. (Caryophyllaceae) have been uniquely regenerated from maternal, immature fruit tissue of Late Pleistocene age using in vitro tissue culture and clonal micropropagation. The fruits were excavated in northeastern Siberia from fossil squirrel burrows buried at a depth of 38 m in undisturbed and never thawed Late Pleistocene permafrost sediments with a temperature of −7 °C. Accelerator mass spectrometry (AMS) radiocarbon dating showed fruits to be 31,800 ± 300 y old. The total γ-radiation dose accumulated by the fruits during this time was calculated as 0.07 kGy; this is the maximal reported dose after which tissues remain viable and seeds still germinate. Regenerated plants were brought to flowering and fruiting and they set viable seeds. At present, plants of S. stenophylla are the most ancient, viable, multicellular, living organisms. Morphophysiological studies comparing regenerated and extant plants obtained from modern seeds of the same species in the same region revealed that they were distinct phenotypes of S. stenophylla. The first generation cultivated from seeds obtained from regenerated plants progressed through all developmental stages and had the same morphological features as parent plants. The investigation showed high cryoresistance of plant placental tissue in permafrost. This natural cryopreservation of plant tissue over many thousands of years demonstrates a role for permafrost as a depository for an ancient gene pool, i.e., preexisting life, which hypothetically has long since vanished from the earth's surface, a potential source of ancient germplasm, and a laboratory for the study of rates of microevolution.

Ich kann mir vorstellen dass man mit Eiszeit- Obst nen gewaltigen Verkaufshit machen könnte...
