It is interesting to note that when Harpenden complain against the prospect of Luton airport growth-due to environmental impact- it is a shame they do not mention how many homes within Harpenden have very large swimming pools, which I am sure has an even more impportant impact on our water resources!
In turn everytime a Monarch passes over their gardens I am sure the noise from the wings causes them disturbance? Just maybe that is why the Monarch butterfly is dwindling in habitats!
