LCA for different production Systems

In this section a short description of four pig production systems is given - two Danish systems and two French systems. These systems are more or less different in terms of housing and the productivity of the pigs indicating that the environmental impact may be different. At the end of this section you are asked to give your opinion on which of these pig production systems you believe have the largest and the lowest environmental impact in terms of 'Global warming potential', 'Acidification potential' and 'Eutrophication potential'.
