We have traded goods across continents for centuries, in some cases for thousands of years. But it was in the 20th century that globalisation came of age with most primary goods being sourced internationally.

Or is globalisation a positive force enriching our experience, and localism conservative and backward looking leading to higher prices, fewer goods, and radically lower living standards?
