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.

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.
