A large advantage of CEA practices is the positive environmental impact due to the increased reliance on local and regional food systems, and a decreased need for cross-country transportation for fresh produce. In addition, CEA uses fewer resources; resources like water, soil, pesticides, and overall land usage. Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations.Sustainable farming practices include: using compost, cover crops, and rotational grazing to build healthy living soil; rotating crops and using companion planting to attract beneficial organisms to fight pests; integrating crops and livestock; planting trees and shrubs to increase biodiversity

I believe that an environmental control is an important aspect in farm structures design. Undesirable environmental conditions may put stress on livestock, human worker in farm building. Environment parameters affect comfort and health of animals and ultimately affect production. Crops grown using this method include micro greens, leafy greens, tomatoes, peppers, strawberries, herbs and medicinal cannabis. The Controlled Environment Agriculture Market was valued at US$ 74.45 Bn. in 2021 and is estimated to reach a value of US$ 157.28 Bn. in 2029. The Global Controlled Environment Agriculture Market size is estimated to grow at a CAGR of 9.8% over the forecast period. CEA technologies include hydroponics, aeroponics, aquaculture, and aquaponics. Different techniques are available for growing food in controlled environment agriculture. Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Considering solutions from various viable practices and innovations, CEA is a sustainable solution to critical challenges. Comparing advantages versus traditional field production, CEA offers some distinct improvements in sustainable resource management and value creation in food production. While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices. Farmers are being paid to sequester carbon to mitigate climate change, to improve watershed management and to conserve biodiversity.
