A few years back, we at the Environment Report did a comprehensive series called, "The Ten Threats to the Great Lakes." Doing our best to make it comprehensive, we broke each of the Ten Threats into several stories.
We joked that the "Ten Threats" series turned into a 33-part series as we dug deeper into the issues.
For the series, I traveled to northwest Ohio and met with Lynn Davis. His grandfather had started a farm drainage business in 1910 using a steam powered trenching machine. Davis later took over the business from his father and uncle.
It being the age of multi-media production, I put together this audio slideshow of that visit. My goal was to give you a picture of what "farm drainage tile" is and why it's important.
