Globalization refers to the increased economic and cultural exchange across international borders. It involves the production, delivery, sale, and movement of goods across countries. Globalization has increased trade through advances in technology that allow for quicker and more efficient international trade. It also leads to the spread of ideas and culture through shared media across borders. A key part of globalization is the rise of transnational corporations that operate in multiple countries. While globalization can increase economic opportunities and spread ideas, it also faces criticisms such as potentially exploiting weaker countries and spreading harmful ideas and pollution.
