Example of tree shedding pollen
Every year, in August, this tree releases masses of pollen which rises up in a continous moving cloud, making it look like the tree’s on fire. This continues for many hours over several days.
And this is from just one tree. Imagine the amount released over a larger area of woodland! A nightmare for those allregic to tree pollen. (watch video)
Naturally, we have evolved to cope with much of this airborne debris – but even so, our immune system has an awfully big job to do. And sometimes it gets things wrong, provoking the body into a violent response that we call an allergy. Unfortunately, allergies to airborne pollution seem to be on the increase.
