livestock, food -- cause for concern?

GRAIN (from their website, "GRAIN is an international non-governmental organisation (NGO) which promotes the sustainable management and use of agricultural biodiversity based on people's control over genetic resources and local knowledge.") has an upcoming special issue of their flagship periodical,
Seedling, on livestock. From their release about that livestock issue:
"we take a close look at the livestock industry. Behind the scenes this global industry is going through a rapid process of concentration as it extends its control over livestock farming. As consumption of meat increases, hundreds of thousands of small farmers have been tied into production contracts mainly for the export market. Furthermore, we are heading for more diseases, more deadly types of disease, and more capacity for these diseases to spread. And yet, the international response fails to reflect the seriousness of the situation. Meanwhile traditional cultures dependent on livestock are also being further marginalised as illustrated in this issue of Seedling in Mongolia and Niger."

Is the knowledge about these issues freely available? What stops people from using it?
