Nature Recycles.

Yes nature recycles. Did you ever stop to think about it? Food is made from matter. Most of this matter is absorbed from the soil by the activities of any kind of living plant but a good deal of it is also absorbed from the air. This has interesting details especially to one who has biological interests in improving the food production process.

Carbon dioxide is absorbed from the air by plants then the carbon is extracted and then oxygen is released. This carbon is then combined with nutrient matter from the soil in a solar powered endothermic process to create carbohydrates. The basic building block of plants and food. A simplified description of a complicated process to be sure.

But this extraction from the soil will eventually deplete it. When this happens then plants can no longer live in it. This condition is usually remedied with fertilizer. Fertilizer is usually made up of dead cellulose and/or defecation by products that of course will break down in the soil into basic plant nutrient matter. Nature recycles. All of this will reenter the process all over again and become food. This has been a scientifically established process for a very long time and some of America's founding fathers contributed to this knowledge.

This may come as a shock but their is no such thing as "virgin" food. You may be eating it but it has been eaten before. This is the way it works and it cannot be changed. If this were not so the Earth's nutrients would have been depleted long ago and all life would have since starved to death. The possibility of crop death from depleted soil is something that farmers are always working to prevent because many have seen it.

Now here is an issue that gets more serious. Many cities dump their sewage into rivers thus into the oceans. This will eventually cause some balance in nature problems. In the extreme this would mean an overly enriched ocean with red tide plagues and an otherwise difficult environment for marine life and also a dead depleted barren landscape unable to support life. This sewage fertilizer should be dumped back on the fields were it belongs but that doesn't always happen. But this is the thing with money/capitalistic systems and that is it always goes with what is cheap and not always with what is best.
