| @indianwolf1992: I think it's a combination of factors. Climate - most of these animals thrive in a temperate climate, and the temperate climate belts happen to be largely occupied by developed countries. Tradition - partly because we associate the products from some countries with quality, such as Chinese silk and Danish fur, and partly because it means that the infrastructure to support the production is in place. The heavily industrialized agriculture of the developed countries, which means that the production cost per unit is low. Trade barriers - which means that for instance in the EU, products from non-EU countries are imposed with tariffs, while products from within the EU are not, which of course encourages consumption of EU-made products. And export subsidies - which mean, for instance, that in some developing countries powdered milk produced in the EU is cheaper than locally produced milk. |
