Dutch designer Daan Roosegaarde has spent much of his career seeking artistic solutions to solve our environmental woes. His past projects include "Bioluminescent Trees" to light streets, a "Smog-Free Tower" to clean Beijing's polluted air, and "Gates of Light," which uses the headlamps of passing cars to illuminate the 60 floodgates of the Afsluitdijk, a major dam and causeway in the Netherlands. Now, the creative artist is hoping to use his skills to solve a pressing global issue - space junk!
