Was heute auf dem Teller liegt, sieht noch so aus wie vor 50 Jahren, ist es aber nicht.
Bei unserem Lucerne Minds 14/2 Treffen ging es um das Thema "Essen heute" bzw. um die Verbreitung von Gentech-modifizierten Lebensmittel, welche Firmen die grossen Treiber dahinter sind und ob es gentechnisch veränderte Lebensmittel braucht.

15. • The defenses of the potato plant have fought off the spores, rendering them harmless
• “crops remain controversial in Europe, and only two are approved for planting in the
EU.”
• How genetically modified crops could help protect the world’s food supply
• defenses against plant diseases, which annually destroy some 15 percent of the
world’s agricultural harvest.
• Climate change is likely to make the problem far worse
• Creating a potato variety through conventional breeding, for example, takes at least
15 years; producing a genetically modified one takes less than six months.
• But the lengthy testing and regulatory processes for genetically modified crops, and
the danger that consumers will reject them, mean that only “a handful of large
companies” can afford the expense and risk of developing them, he says.
• But recent genomic breakthroughs are encouraging. Scientists have sequenced the
genomes of crops such as rice, potatoes, bananas, and wheat. At the same time,
advances in molecular biology mean that genes can be deleted, modified, and
inserted with far greater precision. I
