Should corn be considered an invasive species in the Midwest?


I agree with commenter Bryan Krause in that this question requires opinion -- but I think it only requires opinion as to the definition of what we consider "invasive". 

The concept of an "invasive" species is highly contested among biologists. It is often used interchangeably with the terms non-native, non-indigenous, and alien. 

Some people think we should consider a species as 'invasive' even if it is native to the region but is causing "economic or environmental harm or harm to human health". For example, the USDA considers Juniperus virginia a native species, despite its spread from plantings and its economic and ecological impacts in 'invaded' regions.
