Final answer:
The rivalry between nations can impact the people living in those areas in terms of economy, social and cultural aspects, and psychological well-being.
Step-by-step explanation:
One of the major impacts is on the economy. Rivalry can lead to trade restrictions and tariffs, which can negatively affect businesses and individuals who rely on trade with the rival country for their livelihoods.
Another impact is on the social and cultural aspects. Rivalry often leads to increased nationalism and patriotism, which can result in stereotypes, prejudice, and discrimination against people from the rival nation. This can create tensions and division among the people living in those areas.
Lastly, rivalry can also have a psychological impact on the people. Living in a region with constant tension and hostility towards another nation can create anxiety, fear, and stress among the population.
