The local prevalence of non-native invasive species of plants and animals makes a strong case that it is. We have to look no further than the starlings feeding among the dandelions in our yards to find invasive species. But, most of our very agricultural crops that we depend on for food have origins outside of our borders.

Invasive species were either deliberately or accidently introduced through man’s actions. There are nearly 50,000 invasive species in this country, half of them are plants and most are pathogens or diseases with lesser numbers of insects and vertebrate animals.
