He's right. Western Europe heavily imports laborers from Eastern Europe, Turkey and North Africa for many crops. Germany opened its borders at the height of the first Covid-19 wave to allow workers from Romania to come, when Romania was a hot bed for Covid-19.
Many Western countries are self sufficient agriculturally and they are huge exporters.
Agriculture is a cornerstone of national security. Life sucks when you are rationing fuel or imposing lights out curfews but it gets dire (and dangerous!) when people starve.
