EarthEcho International, the global nonprofit dedicated to building a youth movement to protect and restore our ocean planet, today announced the three middle school teams selected as the grand prize winners of the OurEcho Challenge. The winning teams were part of a STEM competition designed to engage young problem solvers in protecting the diversity of species and ecosystems that make life on earth possible. The competition is made possible through the support of Aramco Americas. Team Algae Biofiltration, Team Habitat Hotels, and Team Springtails were selected after presenting their projects virtually to a panel of judges and members of the public on June 11, 2021, during a Facebook Live event. A panel of judges—comprised of youth, environmental and corporate leaders, engineers, scientists, and educators—reviewed presentations from 10 finalist teams and selected the three grand prize winners based on their projects’ inspiration, scientific rigor, feasibility, and how well the team communicated.
