A farmer in Southern Alberta was having a problem with insect pests, so he decided to use chemical control methods to get rid of them. After months of spraying his crops with the same chemical pesticide, the farmer noticed that the insect pests were NOT dying; but instead, he was finding dead hummingbirds around his farm.
After spraying his crops with the pesticide, the dead hummingbird is most likely an example of …
