There is an unfortunate tendency by the Americans to assume that what applies in their country is the same worldwide, and then others outside the USA take these 'facts' and assume they are correct.
Think of the major grain producers (not exporters) in the world - USA, Canada, Argentina, Australia, Egypt, India, China, Ukraine, Russia - do you really think that most of this grain is used for feeding animals? Considering that the major exporting countries (USA, Canada, Argentina, Australia) sell almost all exports to countries that have low consumption of meat, such as China and India, this seems unlikely.
The elephant in the room that nobody mentions is the increasing world population - that is the root of almost every environmental problem.
