Its a case of trying to show us how the hell we can feed 7 billion people in the future. Unfortunately, the program has simply shown how the big players have to f#+k around with chemicals and methods that frankly should perhaps be going backwards rather than forwards in terms of husbandry and farming methods.
There is a large movement in the uk that want better farming methods than the large monoculture type of farming. Particularly where livestock is concerned.
I did find it obscene that a pig farmer who is growing rare breed pigs should go into a large commercial piggery in the states and realistically not put even the slightest argument against doing it that way. Even away from the farmer!
