[Edit] Here's an article I found on organic produce, although I'd wager there's a fair bit of bias. But like I said, I'm not in a position to challenge the status quo just because I think something might taste better, or would benefit their career choice. http://skeptoid.com/episodes/4019
The criteria here for organic food is pretty strict, still one has to be choosy and read labels. As far as pesticides go, I don't use anything except safer soap. It basically is a biological , non-toxic soap that blocks the breathing spicules of insects, thereby suffocating them. I have birdfeeders and water dishes for birds to encourage natural pest predation, as well as a healthy local anole population. I don't spray the yard for insects. The cats and dogs are groomed everyday, and we use diatemaceous earth. All it is is the skeletons of old dead sea creatures, but it cuts the exoskeletons of bugs and makes them bleed. I don't have a lot of garden pests, actually.
Of course plants make toxins, and those naturally occuring toxins were used hundreds of years ago, pyrethrin by the chinese, for example. (It comes from chrysanthemums, members of the daisy family). It is true, however, that things that are "naturaly occuring" can be toxic.
As far as taste, home grown and organically farmed veggies taste better because they are picked when mature. Produce picked while green and ripened with ethylene gas (which is a naturally occuring product of fruit ripening) tastes less flavorful because the flesh/sugars/cell structures in the ovary/seed/fruit/vegetable haven't broken down and released all the components that make them taste good. Plants, (especially orchids) are underestimated for their "cleverness". Humans have been pherome and aroma tempted by plants for years to eat plant young and spread their seeds.
I do understand, though, how much it does cost for planters, hardware, growing medium, and other startup costs.
Oh, and as much as I agreed on several points teh author made, he omitted several important issues regarding farming. The fact that hundreds of arable acres of farmland have been turned into housing developments, and for many home gardeners, growing produce or having l is forbidden by homeowner associations, and in some cities, livestock of all forms is illegal.
Knowing me, I will be out in teh garden one day, forget to eat, and die of a diabetic coma under a hanging basket of strawberries.
