How U.S. agriculture affects the world...?

Question

i'm writing an essay on the ways that agriculture affects the world...i've come up with a few reasons, but they are all really weak. can anyone give me a few stronger examples to put into my essay, it would mean a lot.

Answer 1

The US used to export a lot of agricultural commodoties, but now we are exporting less product, but more and more scientific information.  Genetic research and biotechnology now probably have a greater effect on the world today than what we export.

Answer 2

I would say that the main way is through charity.  The United States gives more to other countries than anyone else, and a lot of that is in the form of food.  A tremendous amount of US agricultural products are used, essentially, to feed the world.
