In truth, it's the type of farming in which farmers use artificial pesticides, herbicides and other conventional farming techniques that is really historically new to us. Before 1940, much of the produce grown and eaten in American homes was totally organic and was often picked no further than one's own backyard.

The use of chemical additives and even farm implements we see today gradually found its way into farming in the first half of the Twentieth Century. In 1950, there were three million tractors in the US, up from 600 tractors in 1910. At about the same time, proponents of organic farming techniques began to practice their trade, beginning in Central Europe and India around 1920.

Organic farming methods began to reach consumer awareness, beginning in the 1950s and, in the following two decades, there was an increasing concern about the environmental effects of farming techniques using chemical pesticides and herbicides.

This was when food-purchasing cooperatives and specialized organic food producers came to the forefront among some consumers.

In the 1970s and 1980s, regulators recognized a growing need for some way to provide organic certification to those farmers who followed specific growing rules and who used approved growing techniques. It wasn't, however, until the 1990s that the formal or governmental certification of organic foods became available in the US and in several countries throughout the world.

In the last two decades, the availability of organic foods on the market grew dramatically and, at one point, the surge of growth of the organic food market exceeded twenty percent per year. In fact, the sales of organic baby food increased by almost twenty-two percent in 2006 alone.

In the last five to seven years, multinational food companies have jumped on the organic food bandwagon and have increased their research and development of foods that could be certified organic. This has led to an increase in the availability of processed organic foods and in the lowering of the cost of these types of products.

In today's time, organic foods continue to be more expensive than their conventional counterparts, in part due to the fact that organic farmers must meet stricter quality guidelines. This is a labor intensive process that drives up the costs of the product.

To meet consumer demand, supermarkets strictly devoted to providing organic foods, such as the Whole Foods Market and Waitrose (in the UK), have gone into business and are providing quality organic foods to consumers. In order to provide organic foods to a larger population, Wal-Mart announced its plans to increase the availability of organic foods to its customers and at a lower cost than the supermarkets.

It appears that, almost as soon as the big farmers began putting synthetic pesticides and herbicides on their crops, a backlash developed and a group of dedicated farmers and consumers worked-and continue to work-toward improving the availability and quality of organic foods for those food consumers who can't grow an organic produce garden in their own backyard.
