What is transboundary pollution?

Transboundary pollution refers to environmental harm that occurs when pollutants cross national borders, affecting air, water, and land in different countries. This issue is significant because pollutants released in one country can travel through the atmosphere or waterways and have detrimental impacts on neighboring countries, creating international concerns regarding environmental health and safety. Examples include acid rain caused by emissions from one country that fall as precipitation in another or industrial runoff that contaminates rivers shared by multiple nations. Understanding this concept is crucial for addressing global environmental challenges and promoting international cooperation in pollution management and sustainability efforts.
