Animal exploitation acts as a hindrance to the availability and quality of education in poorer countries where children are pulled out of school to work in fields growing commodity crops for livestock, or directly watching over livestock. In higher education, decades of animal testing have provided misleading results and hindered human knowledge. Furthermore, large companies with a vested interest in continuing this system of animal exploitation are funders of research and will prevent the publication of research that is negative to their commercial interests. Nutritional information is skewed towards the glorification of animal products, again through funding and lobbying of governments to favor animal products in dietary guidelines. Children are routinely denied the knowledge of where their food comes from and the heavy cost on the environment and on the animals themselves of the industrialized system of animal exploitation is downplayed or ignored altogether. Much of this secrecy is imposed through Ag-Gag laws which prevent investigations of these facilities which would allow the truth to come out. Were society more educated on this issue, people might make better choices as to their nutrition.
