The Canadian thistle is the perfect example. The weed can affect our crops and pastures by forcing farmers to spend extra money on herbicides. Even though herbicides can take care of the weed, it negatively can affect the environment and ourselves when we consume the produce. 1 The U.S. spends 137 billion dollars a year to cover the cost of non native species and the damage they do to our environment.
There is a lot of farm land in our area; therefore, the thistle is a very frustrating weed. If crops are farmed then the weed takes the nutrition from the soil. If animals are farmed then the weed can cause irritation when the animal is trying to eat anything
