Messages on Innovation and Adaptability
Winners of the 2024–2025 Student Video Contest
This year, we celebrated the 14th annual World of 8 Billion International Student Video Contest, with over 3,250 submissions from students in 67 countries and 45 states plus DC. Our global topics included Child Wellbeing, Rainforest Ecosystems, and Sanitation. We were inspired by the effort students put into researching and brainstorming creative, sustainable solutions to issues related to these themes. Through the winning videos, our staff learned about composting toilets, bioremediation techniques, solar-powered vaccine refrigerators, and more. Winners were judged by 51 global experts in sustainability, education, and activism.
Nearly 300 teachers used the contest as a vehicle for diving deeper into engaged citizenship in their classrooms. For the first time, we offered mini grants of up to $500, which helped 17 teachers purchase cameras, microphones, and editing software. More than 500 students, mostly from Title I schools, were able to participate in the contest due to these grants.
This year’s winners inspired us with their innovative and adaptable approaches to improving child wellbeing, protecting rainforest ecosystems, and advancing sanitation through the lens of climate change and population growth. The insightful one-minute videos offer us hope for the future as we think critically about how to sustainably and equitably share resources and preserve them for future generations. In recognition of their thoughtful and creative work, high school winners received $1,200 for first place, $600 for second place, and $300 for honorable mention. Middle school winners received $600 for first place and $300 for second place.
To celebrate the winners, we hosted a virtual film screening in early June, attended by the students, their families and teachers, and Population Connection staff. You can explore this year’s winning videos and learn about their student producers here.
