Because I couldn't upload some videos to play from this site, I'm including the URL to YouTube, Google or other sites where they will play. Here's some examples:
High Cotton is a 5:45min song and slide show about cotton farming from planting to harvest. It could accompany a presentation on arsenic contamination from boll weevil pesticide use and from the use of arsenic as a defoliant. Arsenic does not break down and remains in the soil, making cotton fields a poor candidate for urbanization. The health risks when building homes and schools there are too great. Read my white paper, "Soil Issues for Residential Construction," for more info.
