Om inte löven trillar av så gör öronen det
Det senaste förslaget i kategorin “geoengineering” är artificiella träd som är mångfalt effektivare än den gamla sorten.
Enligt en studie skulle de kosta c:a 20 000 USD dollar styck. Men de har ju en fördel. Det blir inte en massa löv och barr som man måste blåsa bort med motordrivna kvastar. Och då spar man ju även på det. Frågan är om öronen, som faller av när man hör detta, ställer till med några bekymmer?
