Give two examples from history to show the impact of technology on food availability.
Two examples from history showing the impact of technology on food availability are:
First, railways played a crucial role in linking agricultural regions to ports. As food production expanded in Eastern Europe, Russia, America and Australia to meet British demand, railways enabled the transportation of agricultural products to ports for shipping. This made food more accessible in distant markets.
Second, refrigeration technology revolutionized meat availability. Animals were now slaughtered at the starting point in America, Australia or New Zealand and transported to Europe as frozen meat. This reduced shipping costs and lowered meat prices in Europe. As a result, the poor in Europe could consume a more varied diet, adding meat, butter and eggs to their earlier diet of bread and potatoes.
Explanation
This question is from the section '2.2 Role of Technology' in the chapter 'The Making of a Global World'. The textbook provides two clear examples of how technology impacted food availability: (1) Railways connected agricultural regions to ports, enabling efficient transport of food grains, and (2) Refrigeration technology allowed frozen meat to be transported from distant colonies to Europe, making meat affordable for the poor. Both examples demonstrate how technological advances in transport and preservation directly improved food access and variety for consumers.
