Here’s what the ancient Greeks and Romans can teach us about the environment and ourselves. From Roman soldiers in crowded camps to emperors cleaning up rivers, there are many lessons to be learned.

Today the perilous state of the environment is often in the news. Many stories describe how Earth is being damaged by human beings and discuss ways to prevent this.

These concerns are not new. Millennia ago, people in ancient Greece and Rome already knew humans were damaging the natural world. Literature from these ancient times contains many references to the environment and the harms it suffers.

Many of these insights ring true today. Polluting the soil we farm, air we breathe and water we drink has clear repercussions. We can only degrade the environment for so long before it will come back to haunt us.
