One mining company is now producing their own fertilizer in the form of Fish Excrement. Why? With mining companies now green and trying their best at re-foresting and re-greening past mining operations, traditional fertilizer was becoming more costly by the year. By growing their own fish and harvesting the fish (Rainbow Trout) "poop" for fertilizer the company now saves money while using an environmentally safe product. Once the fish get to be too big for the pens, they are realeased into nearby lakes & rivers adding to the local fisheries. It's a win win situation for everyone.
