Corn Diesel Crop
This was as high as I could reach over some of the largest corn crops I have ever seen. I was told that most of the corn crops in Belgium is processed to make Bio Diesel. There was simply hectares of these tall, dense corn crops. I think the crew at www.worldchanging.com and www.treehugger.com would be pleased.
