Section 2:

This source talks about the organic farming and the effects of herbicides and pesticides on the environment specially the soil and the water, as this source mentions that all the chemical used as herbicides and pesticides are water soluble and the are sprayed on the soil which itself forms a danger as it could be picked up by rainwater to nearby lacks and water streams which can contaminate drinking water.
The other issue that was mentioned in this source is the effect on the soil and the bacteria that inhabit the soil which is considered beneficiary to the plants as it help in transforming the air nitrogen into nitrates that is needed by the plants to thrive.
