Earth's population has surged by 4 billion people since the first Earth Day in 1970.

Earth Day 1970 - 2019: No Time To Waste #datavisualization · 3:20 · Video: American Museum of Natural History · Watch at the source

In short: Since the inaugural Earth Day in 1970, the global population has expanded by 4 billion. This video explores the environmental consequences of this growth, specifically focusing on the massive inefficiency of our global food systems and the resulting impact on greenhouse gas emissions.

While the planet currently produces sufficient food to sustain its entire population, the distribution of these resources remains deeply unequal. A significant portion of this output—one-third of all food produced—is lost or wasted.

This waste represents more than just discarded calories; it signifies a massive squandering of the natural resources required for production. By examining these patterns, the video highlights how food waste contributes directly to greenhouse gas emissions and suggests ways individuals can participate in addressing these systemic challenges.
