Healthy food Quote by Jeff Lowenfels
““Chemical fertilizers, pesticides, insecticides, and fungicides affect the soil food web, toxic to some members, warding off others, and changing the environment. Important fungal and bacterial relationships don’t form when a plant can get free nutrients. When chemically fed, plants bypass the microbial-assisted method of obtaining nutrients, and microbial populations adjust accordingly. Trouble is, you have to keep adding chemical fertilizers and using “-icides,” because the right mix and diversity—the very foundation of the soil food web—has been altered. It makes sense that once the bacteria, fungi, nematodes, and protozoa are gone, other members of the food web disappear as well. Earthworms, for example, lacking food and irritated by the synthetic nitrates in soluble nitrogen fertilizers, move out. Since they are major shredders of organic material, their absence is a great loss. Without the activity and diversity of a healthy food web, you not only impact the nutrient system but all the other things a healthy soil food web brings. Soil structure deteriorates, watering can become problematic, pathogens and pests establish themselves and, worst of all, gardening becomes a lot more work than it needs to be.””

Relying on synthetic chemicals disrupts the soil ecosystem, killing beneficial microbes and earthworms, leading to poorer soil health and more work for gardeners.
In simple terms: Chemicals harm soil life, reducing soil quality and increasing effort.
Reduce chemical inputs and restore microbial diversity.
