Farming affects all of Earth's systems listed:
- **Atmosphere:** Farming activities can influence local and global climate patterns through emissions of greenhouse gases, changes in land use, and the release of aerosols.
- **Hydrosphere:** Agriculture impacts water systems through irrigation practices, water consumption, and potential runoff of fertilizers and pesticides into water bodies.
- **Geosphere:** Farming alters landforms and soil structure through practices such as plowing, the application of chemicals, and land clearing, which can lead to soil erosion and changes in land cover.
- **Biosphere:** Farming directly affects biodiversity, ecosystems, and habitats through land use changes, and it can impact the variety and population of plant and animal species.
In summary, all four systems—atmosphere, hydrosphere, geosphere, and biosphere—are influenced by farming practices.
