Organic farming is incredible and it works for you in many ways. The results are worth all the trouble to learn the techniques. The insecticides used on food has it's beginnings from World War I when they discovered that the NERVE GAS being used to kill soldiers also killed bugs. When gardening became a profit structure instead of a health quest, insecticides like DDT became the holy grail. We are now living with the results of that great experiment. Weight gain is one of the results and is the major contributor to obesity along with the vegetable oils and bad saturated fats are also big players in this issue.
Only about 4% of the entire food supply in America is organic. Organic must also be accompanied by food grown on fertile soil as opposed to the depleted, over cultivated, worn out soils being used to produce food that is 50% less nutrients than we had just 25 years ago. The good news is that people are now consuming more organic food than farmers can produce and the demand is growing. I believe Americans are beginning to see the real picture of what many large corporations have done to our food supply.
I saw an incredible example of what organic farming technique can do. I was a member of a group of a small city farm coop that was formed to grow our own food. There were the organic people and the chemical people separated so as not to contaminate each other's crops. Of course, the organic people were always at odds with the chemical people as to who was growing the best crops. The organic side grew these wonderful tasting foods and the chemical people grew food that was not as good, but they both had good appearances. The example was one small organic farm had been abandoned and weeds were about 4 feet high all over the area. All the rows of lettuce, tomatoes, etc. were eaten by aphids and bugs I've never heard of, except for one lonely, large, cabbage plant that was absolutely beautiful and covered with weeds. There was not a bug on it and it was huge. When we uncovered the plant and cleared the weeds, no one could believe it. So how did this happen? Right next to this perfect cabbage plant were two very large onion plants. Bugs hate onions.
No we do not need insecticides. We need dedicated farmers interested in health and welfare of this Nation, unlike corporations like MONSANTO that is contributing technology that is destroying the very fiber of quality, healthy foods and replacing them with genetically engineered garbage, seeds that contain insecticide genes that create corn plants with insecticides built into the corn, and terminator genes so farmers have to buy the seeds from them instead of using decades of environmentally, biodiversified, adapted seeds they have used for generations, and forcing their corporate will on farmers by suing huge numbers of them for patent infringement on seeds where they have patented life. Amazing.
Any word with "......cide" at the end of the word is designed to kill, not be nutritious. Everyone of us needs to take back the health of our food by refusing to buy the garbage and demanding quality.
good luck to you ---
