Abstract
Healthy food is crucial in the modern world, but farmers and market vendors are employing more chemicals, which is polluting the waterways overall. Farmers are primarily using more chemical fertilizers, which have an impact on the soil, resources, animals, plants, and human health. They're all contaminated because of inorganic farming. Therefore, the key is to avoid using chemicals in marketing and to use less chemical fertilizers to increase yields. Consequently, this lowers the risk of developing cancer, heart attacks, strokes, and many other illnesses. Enhancing organic yields is crucial because it will encourage the government to get involved, take the initiative to encourage farmers to use organic fertilizers, market organic products separately, and encourage government websites to offer free certification and additional subsidies to organic farmers. The article outlined the key benefits of adopting organic farming, the ways in which it differs from chemical farming, and how it protects the ecology and climate.
