A macroeconomic impact of organic food would be a win-win for the environment and consumers. Farming with organic principals causes less pollution and erosion. It is more sustainable as it depletes the soil less the conventional agriculture. Consumers would have healthier food with less pesticide residue. Increasing organic farming would be good.
No, the macroeconomic impact of organic food is not desirable, because it is very expensive to make and distribute. People who only purchase organic food have less money for other things. If we all had to buy only organic food, the economy would contract. Fortunately, there are not so many people that buy organic food that it makes a difference.
