have you ever eaten tasteless produce?

I wanted to a bit more research into pesticide and insecticide use in modern agriculture. The first pesticide that was developed was DDT in 1939. It was very effective at controlling pests, however it was later realised that it also had an effect on reproductive cycles of animals higher up the food chain and was banned in 86 countries in 1972.

The development of DDT, however, paved the way for new pesticides to be developed and when farming became more intensive in the 1950’s these pesticides and herbicides became commonly used in industrial agriculture.

However, an interesting article by the University of Queensland written in 1996, maintains that although pesticides and insecticides reduce pest numbers, they do so temporarily, and when insects and other pests evolve to become resistant to the pesticides, their numbers explode to levels higher than before the use of these toxins. This also, inevitably, costs the farmers more than they would have had to invest, had they not used pesticides at all.

A large number of deaths in the developing and developed world can be attributed to close contact with pesticides, in farmers and farm workers, using them on agricultural produce.

Other practices such as forcing fruit and vegetables to ripen by bombarding it with specific gases, means that the mineral and vitamin content of contemporary fruit and vegetables are also reduced. The fruit or vegetable can only harvest nutrients from the soil and sun while it is still on the vine, and when the produce is picked before it is ripe and then chemically ripened, it decreases the mineral content of the fruit and vegetables.

Interestingly, organic farmers do also use pesticides, although these are naturally derived, and one of the precepts of organic farming is that synthetic pesticides are not used on produce. One article did suggest that the pesticides used on organic farms, are actually just as dangerous as the chemical counterparts.

However, organic farmers also use other methods to reduce the impact of pests, such as integrated pest management, using pest resistant varieties, using predatory insects to kill the plant eating insects, employ mechanical pest traps, and eliminate pest nests by ploughing under harvested crops.

Crop rotation can also be used to replenish the nutrients in the soil as they have been used by a particular plant, and companion planting, which can increase diversity of the population of crops and reduce insects and pests in that way.

Animal livestock is fed wheat, corn and soy that is heavily sprayed in nutrient depleted in soil, and these toxins accumulate in the flesh and fat of these animals. Meaning that eating meat thereby puts the consumer in contact with higher levels of toxins than are even available through fruit and vegetable.

For my two cents, it is a serious concern that much of the produce we consume regularly is tasteless, spoils easily and is chemically ripened. I think that it reduces our levels of health and resilience.

Although the light source of this operation is synthetic, it does give people the capacity to eat produce without toxins.

The Environmental Working Group yearly compiles a list of fruit and vegetables that have the highest levels of pesticide residues. These are currently:

Apples, celery, capsicum, peaches, strawberries, nectarines, grapes, spinach, lettuce, cucumbers, blueberries and potatoes.

The key here is to buy local AND organic wherever possible. Some local farms use sustainable methods, but have not been certified organic due to the cost involved in getting accreditation. The best practice is to visit local farmers markets and to ask the farmers themselves, what their pest control practices are!
