Organic produce contains no synthetic pesticides. Chemicals such as fungicides, herbicides, and insecticides are widely used in conventional agriculture and sometimes residues remain on (and in) the food we eat.
Organic food is often fresher because it doesn’t contain preservatives and additives that make it last longer for transit. Organic produce is often (but not always, so watch where it is from) produced on smaller farms near where it is sold.
Organic farming is better for the environment. The best organic farming practices reduce pollution, conserve water, reduce soil erosion, increase soil fertility naturally, use less energy, and even sequester/store carbon. Farming without synthetic and dangerous pesticides is also safer for nearby birds, insects, and other animals as well as the people who live close to farms. Bees and other native pollinators, an integral part of our food ecosystem, have been imperiled by the prolific use of chemicals in agriculture.
