Even if you grow your own veges and don't use pesticides and use natural fertilizers such as animal droppings or fish scales and seaweed, you still don't have an organic garden unless you've got no pollutants comming from anywhere including seepage through the soil, air pollutants and water pollutants.

If you live anywhere near the city you are fighting a losing battle to save yourself from pollutants although with that in mind, I live in the city and what plants and veges we grow for the table don't have pesticides used on them and in general, it's water from the tank used for watering.

It's difficult to protect your family in modern times, but I still think that any little thing you can do is better than doing nothing.
