Examples of the different types of global exchanges which took place before the seventeenth century:
→ Textiles, spices and Chinese pottery were exchanged by China, India and Southeast Asia in return for gold and silver from Europe.
→ Gold and foods such as potatoes, soya, groundnuts, tomatoes and chillies were first exported from the Americas to Europe.

The global transfer of disease in the pre-modern world helped in the colonisation of the Americas because the native American Indians were not immune to the diseases that the settlers and colonisers brought with them. The Europeans were more or less immune to small pox, but the native Americans, having been cut off from the rest of the world for millions of years, had no defence against it. These germs killed and wiped out whole communities, paving the way for foreign domination. Weapons and soldiers could be destroyed or captured, but diseases could not be fought against.

The British government's decision to abolish the Corn Laws was the inflow of cheaper agricultural crops from America and Australia. Many English farmers left their profession and migrated to towns and cities. Some went overseas. This indirectly led to global agriculture and rapid urbanisation, a prerequisite of industrial growth.

The coming of rinderpest to Africa caused a loss of livelihood for countless Africans. Using this situation to their advantage, colonising nations conquered and subdued Africa by monopolising scarce cattle resources to force Africans into the labour market.

Most of the victims of world war belonged to young generations of working men. As a result, it reduced the workforce in Europe, thereby reducing household income. The role of women increased and led to demand for more equality of status. It made the feminist movement stronger. Women started working alongside men in every field. Women and youngsters became more independent and free with long-term effects.

The impact of the Great Depression in India was felt especially in the agricultural sector. It was evident that Indian economy was closely becoming integrated to global economy. India was a British colony and exported agricultural goods and imported manufactured goods. The fall in agricultural price led to reduction of farmers’ income and agricultural export. The government did not decrease their tax and so, many farmers and landlords became more indebted to moneylenders and corrupt officials. It led to a great rural unrest in India.

The decision of MNCs to relocate production to Asian countries led to a stimulation of world trade and capital flows. This relocation was on account of low-cost structure and lower wages in Asian countries. It also benefitted the Asian nations because employment increased, and this resulted in quick economic transformation as well.

Two examples from history to show the impact of technology on food availability were:
→ Faster railways, lighter wagons and larger ships helped transport food more cheaply and quickly from production units to even faraway markets.
→ Refrigerated ships helped transport perishable foods such as meat, butter and eggs over long distances.
