Why has pollution become a global concern?

Transboundary pollution issues include pollution from rivers and lakes (since some rivers and lakes are shared by different countries), atmospheric pollution, and global climate change caused by an increase in carbon dioxide in the atmosphere.

Pollution is the responsibility of the polluter, but it also affects some other countries (downstream countries in the case of river pollution, for example). Since no one can keep pollution contained in the immediate vicinity of the source, pollution is an international and transboundary problem, and any form of pollution is a real global health risk.

Pollution has become a global concern due to its detrimental effects on human health, ecosystems, and the environment. Industrial activities, urbanization, transportation, and agricultural practices release pollutants into the air, water, and soil, leading to a range of problems such as respiratory illnesses, water contamination, biodiversity loss, and climate change. The widespread nature of pollution means that its impacts transcend national borders, making it a global issue that requires coordinated efforts to mitigate and address.
