Roses are red, violets are blue.....but without scent it seems.
The Independent [as reproduced on CommonDreams] reports on new scientific research which finds that flowers are losing their scent:
"Pollution is dulling the scent of flowers and impeding some of the most basic processes of nature, disrupting insect life and imperilling food supplies, a new study suggests.
The potentially hugely significant research - funded by the blue-chip US National Science Foundation - has found that gases mainly formed from the emissions of car exhausts prevent flowers from attracting bees and other insects in order to pollinate them. And the scientists who have conducted the study fear that insects’ ability to repel enemies and attract mates may also be impeded.
The researchers - at the University of Virginia - say that pollution is dramatically cutting the distance travelled by the scent of flowers. Professor Jose Fuentes, who led the study, said: “Scent molecules produced by flowers in a less polluted environment could travel for roughly 1,000 to 1,200 metres. But today they may travel only 200 to 300 metres. This makes it increasingly difficult for bees and other insects to locate the flowers.”
