Because when they brought the cows back the Autumn Buttercup began to thrive. They took the cows out of the pasture thinking that the Autumn Buttercup would grow better. They noticed that the Autumn Buttercup was thriving in a field nearby where there were cows grazing.

Nature has been developing its habitats for thousands and thousands of years. In time there is a balance where there aren't too many plants and animals, but enough food for each.

It can cause species to extinct. It will take nature hundredsof years to find balance again.
