Next time you drive down the motorway check your windscreen, is it covered in splattered insects? This used to be the case, but now sadly there are so few insects left that in fact our windscreens are mostly clear.

In 2019 a study published by Danish researcher Anders Møller showed that insect numbers splattered on cars declined by more than 80% between 1997 and 2017. An earlier landmark study by Hallman et al in 2017 stated that “There has been more than a 75% decline over 27 years in total flying insect biomass in protected areas”. This study was breathtaking in its scope and involved nearly three decades of continuous, data collection across 63 sites.
This German study tracked insect biomass in nature reserves— protected land. The insects were gone because the fields around them were sprayed with herbicides and pesticides. Have you ever heard of tramlines? The tramlines I am talking about here are tractor tracks through in particular cereal fields (and vegetable fields).
Next time you drive past a field of wheat or barley, look for these tramlines — those tracks running through the crop. They’re permanent spray lanes, put there at sowing so a tractor can enter the field over and over to apply chemicals. A typical Irish cereal crop gets sprayed four to six times between October and June.
Cereal fields (and increasing grass monocultures where all diverse plants are removed by selective herbicides) are essentially a chemical monoculture from October through June — no flowering weeds (removed by herbicide), no insects able to complete life cycles in or around the crop, nothing for birds to eat. The tram lines are the visible manifestation of the chemical applications. The crop looks green and healthy. What isn’t visible is the biological silence inside it. They’re the signature of an industrial spray programme, written in bare soil across every tillage field in Ireland.
There is more evidence of the devastation wrought by chemical agriculture, populations of European grassland butterflies are estimated to have declined by 50% in abundance between 1990 and 2011. In England, the total abundance of butterfly species declined by 58% on farmed land between 2000 and 2009, despite a doubling of conservation spending.
And finally in the USA in the last three decades, monarch butterfly populations have declined by 80–95%. Researchers studying monarchs found on average traces of seven pesticides in each individual butterfly studied. But the application of glyphosate and the destruction of milkweed a key plant that Monarchs feed on is a critical part of the population collapse.
So, the next time you drive down a motorway and you notice those tram lines, have a look at the insect splatter on your windscreen and remember the application of herbicides and pesticides and fungicides do not only impact our health but also the health of our little living friends that we share this earth with and whom we rely on for pollination and our food. (Over 75% of human-cultivated crops worldwide depend directly on insect pollination. About 88% of all flowering plants are pollinated by insects.)
As always thank you for your support, it means a great deal.

PS It is definitely holiday season and we are seeing harvest rolling in from the fields and also a marked increase in the absence of orders. If you are considering ordering please do, it will help us enormously especially at this time. Thank you.
