There are likely to be additional resources in other areas of this sustainability section that also showcase the benefits of organic/regenerative/agroecological farming methods on the human and planetary health. Please be sure to look through other resource areas as well.

- The concept of one health highlights that human health is not isolated but connected to the health of animals, plants and environments.Â
- In this Review, we demonstrate that soils are a cornerstone of one health and serve as a source and reservoir of pathogens, beneficial microorganisms and the overall microbial diversity in a wide range of organisms and ecosystems.

- Found significantly higher levels of these phytochemicals in addition to vitamins C and E. In comparison, pesticide residues and toxic metal content was four times as high in conventional fruits.
- Â Researcher state that shifting to organic farming can increase the phytochemical content in produce to the current equivalent of eating 2-4 portions of fruits and vegetables!

- Organic agriculture reduces the greenhouse gas (GHG) footprint of farming by eliminating most fossil fuel–based inputs, and it builds climate resilience by promoting healthy soils, diversifying food crops, and supporting threatened wildlife habitats and biodiversity.Â
- Data show that organic farming emits less nitrous oxide by avoiding chemical fertilizers and pesticides commonly used in conventional agriculture, and organic livestock production leads to fewer methane emissions compared with conventional concentrated animal feeding operations (CAFOs). Â
- Research demonstrates that organic agriculture benefits our health by dramatically reducing exposure to agricultural pollution in air, water, and food. Farmworkers and others working and living near conventional farms suffer serious acute and chronic health ailments associated with pesticide exposure, and studies indicate that pesticide residues in our food may be harmful to consumer health.

- The diets found to have the lowest environmental impacts were the vegan, climatarian, and Mediterranean diets. These low-carbon-footprint diets can likely be attributed to a reduced reliance on ruminant meat (cattle and sheep) and processed food consumption, while diets with high carbon footprints are more dependent on ruminant meat and saturated fat.
-  Making simple substitutions within each individual’s diet can be advertised as an effective approach to collectively lower the environmental impact in tandem with improving health and longevity.

- Industrial agriculture requires increasing amounts of fertilizers and pesticides to maintain yield. This seems to be the result and/or the cause of a poor microbial diversity in the soil. Soil erosion and climate change also affect microbial biodiversity and contribute to the loss of large areas of arable land and their microbial populations
- Since microbes from fruits, salads and vegetables join the human gut microbiome, the plant microbiome can affect the gut microbiome and thereby human health.

- An active soil microbiota plays an important role for various soil based ecosystem services such as nutrient cycling,erosion control and pest and disease regulation
- Overall, we found that organic systems had 32% to 84% greater microbial biomass carbon, microbial biomass nitrogen, total phospholipid fatty-acids, and dehydrogenase, urease and protease activities than conventional systems

- Diet choices and the associated food production methods also have important impacts on environmental sustainability
- Organic dairy products, and perhaps also meats, have a higher content of omega-3 fatty acids compared to conventional products. However, these differences are likely of marginal nutritional significance.
- Of greater concern is the prevalent use of antibiotics in conventional animal production as a key driver of antibiotic resistance in society; antibiotic use is less intensive in organic production.
- Overall, this review emphasises several documented and likely human health benefits associated with organic food production, and application of such production methods is likely to be beneficial within conventional agriculture, e.g., in integrated pest management.

- Organic farming is one of the best ways that does not only reduce the deterioration of water quality but also decrease food toxicity.
- Fields that are organically managed continuously for years have fewer pest populations and were attributed to increased biodiversity and abundance of multi-trophic interactions as well as to changes in plant metabolites.

- Lower yields can range depending on the situation and they say it’s possible to see a lower yield that’s only 5-9% less than the traditional counterpart. This same study also found that it can be a larger amount of 30-40% less of what the organic crops are producing. It’s fascinating that there can be such a wide range of yields with organic depending on the conditions
