Industrial agriculture views the farm as a factory with, let's just say "inputs." These Factories may use pesticides, feed, fertilizer, and fuel and "outputs" such as corn, chickens, and so forth. Their goal is to increase the size and amount of animals, so they can grow faster and make more money. I find this absolutely wrong! You shouldn't give an animal steroids just for it to grow faster, stronger and bigger.
There are many purported benefits of this industrial approach, such as lower food prices for consumers, cheap feed for animal factory farms, a potential energy source to replace foreign oil, and substantial exports to foreign markets. We should really think about our environment and how it will affect it greatly! However industrial agriculture isn't the only method of agriculture. There is also a sustainable approach which
embraces a wide range of techniques, including organic, free-range, low-input, holistic, and biodynamic.
A sustainable approach, based on understanding agriculture as an ecosystem, promises sufficient produce without sacrificing the environment. This is a much better method for farms as they minimize tilling and water usage, encourage healthy soil by planting fields with different crops year after year, and avoiding pesticide use. However it is said that Industrial agriculture is one of the best inventions ever made for the costs and benefits! I believe it's great how you can get cheaper food, greater ability of labour, environmental, economic, and industrial agricultural costs.
