A report on a respected science web site, Phys.Org, says that there is evidence of pesticides in European soils. That is not really a surprise but still worrying. The other part of that will be low organic matter in soil making it more prone to erosion.
Soil should be seen as a vital resource for growing food and not as a sterile medium for industrial agriculture. After 70 years of intensive farming soils are in a worse state and still deteriorating.
The only answer is the wide scale adoption of organic farming methods which cultivate healthy soils producing nutritious food. A good example of what can be done is Riverford Organic.
Or, you can start growing your own organic food!
