Final answer:
The North American Free Trade Agreement (NAFTA) has resulted in an increase in the ease of travel between countries by eliminating trade barriers and promoting economic activities. Special economic zones called maquiladoras in Mexico have played a role in facilitating cross-border movement of people for work.
Step-by-step explanation:
An increase in the ease of travel between countries is an important development that has occurred because of the North American Free Trade Agreement (NAFTA). NAFTA is a trade agreement between Canada, the United States, and Mexico that eliminates trade barriers such as tariffs between each nation. By reducing trade barriers, NAFTA has facilitated the movement of goods and services across borders, which in turn has made travel between these countries easier.
One example of how NAFTA has increased the ease of travel is through the creation of special economic zones called maquiladoras in Mexico. Maquiladoras are factories near the US-Mexico border where raw materials are imported, assembled or processed, and then exported. These maquiladoras have attracted foreign investments and created job opportunities, leading to an increase in cross-border movement of people for work.
In summary, NAFTA has had a significant impact on increasing the ease of travel between countries by eliminating trade barriers and promoting economic activities that require cross-border movement of people.
