Thank you to all the teachers and students who participated in the 2018-2019 World of 7 Billion student video contest. We were blown away by the creativity, passion, and expertise showcased throughout the videos, especially by the 18 winning films.

World of 7 Billion infographic flyer

The contest first ran during the 2010-2011 school year as a “teachable moment” around world population reaching 7 billion. 619 videos were received from 36 U.S. states and four countries abroad in that first year and it was meant to be a one-time event. But we received such positive feedback from teachers – many wanted to participate again and make the contest a permanent project in their courses – that we decided to make the contest an annual event.

Now in its 8th year, nearly 14,000 student-made videos on the impacts of population have been created as a direct result of the contest. Thousands of students are now more aware of the vast connections between population and so many of today’s pressing global challenges.

We look forward to continuing the contest into the future and watching as more students explore the complexities of population growth through film.
