First of all, in industrial farms or large farms, a lot of chemicals are used, such as fungicides and pesticides, etc. Those are known facts. Everybody, every chef or most people....
Foods with lot of chemicals are not as healthy as organic food. You cannot grow organic food in huge, large.... You need greater varieties of crops. Nature will take care of itself.
As for anybody who is saying that we cannot afford organic food for kids, I think that's a very bad statement, because the medical costs are huge compared to whatever extra time we would have to spend on growing organic food. I think the future generation will not look too greatly on the people today who use a lot of chemicals in growing foods.
