Final answer:
Globalization increases the availability of products globally by improvements in transportation, enhancements in technology, and international trade agreements; these developments decrease costs and enhance economic interconnections.
Step-by-step explanation:
Globalization affects trade and the source of products by increasing their availability across international borders and creating a more interconnected global market. Three key developments enabling this are:
- Improvements in shipping and air cargo that have reduced transportation costs, making it more economical to trade goods globally.
- Innovations in computing and telecommunications that have facilitated the management of long-distance economic connections, such as production and sales, at lower costs.
- International agreements and treaties that have been established between countries to promote and encourage greater trade.
These cutting-edge changes in technology and policy have transformed how products are sourced and sold, having a profound impact on global commerce and connectivity.
