You Murderer You!
Arnold van Vliet has studied the number of crushed bugs on front car license plates in Denmark. A similar study was also performed in the UK. From the data, van Vliet extrapolated to come to the following conclusion:
“In 2007, over seven million cars [in the Netherlands] travelled about 200 billion kilometres. If we assume for simplicity that every month the average is the same for all cars, then 16.7 billion kilometres are travelled a month.
“In just the licence plates, 3.3 billion bugs are killed per month. The front of the car is at least 40 times as large as the surface of the plate.
“This means that cars hit around 133 billion insects every month. In half a year, that is 800 billion insects. This is significantly more than we had estimated six weeks ago.”
Extrapolating from Van Vliet's data US publication Treehugger calculated that cars kill around 32.5 trillion bugs in the US every year.
