I assume you mean roamed.

We grow enough food to feed us and a larger percentage of the world. People starve on this planet due to politics not lack of food. We have the most efficient system to produce food and get it to market than any other country, including beef!
The attack on raising cattle is nothing more than another shot by the left to make us feel guilty about what we do and how we live. America, and our way of life, is the best country the planet has ever seen. American exceptionalism is under attack. What is indisputable is this country is a place for exceptional ideas including freedom, life, liberty, and the pursuit of happiness.
