Bees have a laundry list of problems going against them these days. Among them is air pollution, and a new study shows just how air pollution is affecting bees’ ability to find food. By studying how changes in air chemistry affect foraging patterns of bees, researchers from Penn State illustrate that a rise in air pollution is a serious problem for pollinators.
According to PhysOrg:
Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators use to locate needed food, according to a team of researchers led by Penn State. The pollution-modified plant odors can confuse bees and, as a result, bees’ foraging time increases and pollination efficiency decreases. This happens because the chemical interactions decrease both the scent molecules’ life spans and the distances they travel.
The real kicker is that the breakdown process actually creates even more air pollutants which speeds up the breakdown.
Without bees able to find food and thus pollinate plants, not only do bee populations decline but so do many species of plants that rely on their pollination, including crops that humans rely on for food. Decreasing air pollution isn’t only for the best interest of pollinators and plants, but for our own survival as well.
