Wall Chart: A Quick Trip to 8 Billion

Poster for middle level and high school classrooms

World population reached an unprecedented milestone in late 2022: a global population of 8 billion people. Why did our global family grow so quickly? What are the impacts of such a large (and still growing) world population? The Quick Trip to 8 Billion poster aims to answer these questions and more.

Follow the chronological timeline through modern history to see events, discoveries, and inventions that have influenced population size and led us to expand from 1 billion to 8 billion in just over 200 years.

Then flip the poster over for colorful infographics on current and future trends affecting people and the planet. While there are great challenges, like water stress and biodiversity loss, there is also much reason for hope, like increasing renewable energy use and lower maternal mortality. Curious to know even more about these global trends? Check out how these topics connect to the SDGs and go more in-depth here.
