Smell the Roses While You Still Can

A new study has determined that flowers are losing their scent due to pollution from power plants and cars. To make matters worse, not only are we facing a future lacking in the gorgeous scents of blooms, but insects won't be able to find pollen. According to National Geographic News:

Flowers produce volatile scent molecules that bond with pollutants such as ground-level ozone, in the process breaking down the plants' sweet smell.

With more pollution in the air, the aromatic molecules don't remain potent as long and travel shorter distances on the wind.

What you can do
Since the pollution is coming from cars and power plants, the obvious solution would be to drive hybrids or plug-ins (or, even better, walking or biking!) and to either limit energy use or rely on pollutant-free energy such as wind or solar power.
