“In today’s world, where huge numbers are going vegan and vegetarian for the climate, we promote small families as the biggest reduction in one’s carbon footprint, with 100 times more impact than going vegan. Thank you for making that film and sharing the trailer. It’s really good.”

Confronting the Impact of Unsustainable Growth

Today, humanity’s demand for resources vastly exceeds nature’s ability to supply them. Food, water, climate and extinction emergencies are unfolding before our eyes. 8 Billion Angels tells the truth about the conflict between the size of our global population and the sustainability of our planet. It dispels the misperceptions that technology can save us, that reducing consumption is the answer, and that the blame lies solely in the developing world.

At its core, 8 Billion Angels derives its power from stories because audiences connect more deeply to experiences than data and facts. 8 Billion Angels weaves together the voices of people around the world as they confront the growing impact of overpopulation on their lives and the planet.

With passion, humility, and honesty, experts explain the indisputable connection between our environmental catastrophes, unsustainable population and increasing consumption. The consequences to humanity and the planet are laid bare if we do not quickly and dramatically alter our current population and consumption trajectories.
