For example, in the case of Jonai Farms where there are just 12 sows (so a total herd of around 110 pigs at any given
time) on 9ha of paddocks, the 250m
buffer zone from rural dwellings recommended by Australia Pork Limited (APL) is actually wider than the pig paddocks in their entirety, and yet at
times there are no pigs visible in a one - acre paddock
due to low stocking densities.
Due to the ocean's
buffering capacity and the biological pump, as seen in the graph below, the upper ocean can experience upwelling that drives CO2 levels to 3
times higher than what would be expected from equilibrating with the atmosphere.
