optimise for beef production in the regions that can do it most efficiently. The ‘worst’ (where we’re defining ‘worst’ as those that use the most land) 25% of beef producers use up 60% of the total land that is used for beef production. If globally we were able to reduce the amount of beef we eat by 25%, and eliminate this from the ‘worst’ beef producers, land use for beef production would be cut by a whopping 60%.
