World Sky Race Lead Research Scientist Dimitri Deheyn talks about the World Sky Race during his TED Talk, where he focuses on the urgent global issue of microplastics.

The talk addresses the issue of microplastics. It begins by emphasizing what we know from large pieces of plastics in general, then dives into their smaller and more dangerous counterparts. The goal is to answer the "and so what?" question by outlining the routes of toxicity that microplastics may take.

Ultimately, this is a global and long-term issue. That’s why Deheyn stresses the importance of engaging with citizens and educating high school students, who will become the next generation of environmental stewards.

Dimitri Deheyn is a marine biologist and ecotoxicologist at Scripps Institution of Oceanography, UC San Diego. His cross-disciplinary research centers on plastics—especially microplastics—and their toxic potential due to chemical additives and ability to enter organisms and the food chain, including humans.

He emphasizes the power of public education and the role of global citizen science in understanding and combating microplastic pollution. With roots in Belgium, Africa, and South America, Deheyn brings a global perspective to the science of environmental health.

His overarching goal is to help the world better understand microplastic production and distribution and to develop tangible solutions that protect ecosystems and future generations. This TEDx talk, conducted in the style of TED conferences but organized independently by a local community, is part of the growing dialogue on environmental responsibility.
