Mücke als Verbündeter / Rückwirkung von Eingriffen

Beitragvon Alex » Dienstag 27. März 2007, 15:51

Im aktuellen Economist ist ein kurzer Artikel über zwei amerikanischer Wissenschaftler (Johns Hopkins University), die untersuchen, inwiefern man gegen Malaria resistente Anopheles-Mücken züchtet und in der Natur aussetzt. Dort sollen sie dann in der genetischen Selektion den nicht-resistenen Mücken überlegen sein.

Der Artikel ist auch für Nicht-Abonnenten kostenlos online nachlesbar:


Auch wenn die Sache bisher im Prinzip nicht viel mehr als eine Idee ist, stellt sich bereits die übliche Frage, ob ein solcher Eingriff des Menschen wünschenswert ist. Denn er könnte unverhersehbare Konsequenzen haben.

Man denke, viele haben da vielleicht noch nicht viel von gehört, an das enorme Bienensterben der letzten Jahre. Über die Zahlen bin ich mir nicht mehr sicher, aber in bestimmten Regionen der USA soll nach dem Winter 60 bis 70% der Bienenpopulation schlicht verschwunden sein. Es wird spekuliert, dass dies ein Nebeneffekte des Anbaus gentechnisch veränderten Mais ist. Irgendwie ist der Mais gegen einen Pilz immun und irgendwas schädigt dann möglicherweise das Immunsystem der Bienen.


Oder diese Riesenkröten in Australien...
