Humanity has developed an extraordinary capacity to transform the world. Through science, technology, education, infrastructure, economic cooperation, and the exchange of knowledge, societies have expanded what people can achieve individually and collectively. Yet this growing capacity has created a fundamental challenge: the ability to change the world is advancing faster than the ability to anticipate all the consequences of that change. Decisions that appear beneficial in the short term can generate costs that emerge years later, while problems that seem distant can become urgent when several systems begin to interact.

Plastic pollution in the world’s oceans has reached a critical level, with long-term consequences for ecosystems, economies, and human health. While it is widely known that most ocean plastics originate on land, recent research has significantly changed our understanding of how this pollution is distributed globally.
