Knowing Your Food
Sustainable farming has developed as an alternative to the industrial methods that tend to focus more on profit than preservation. Many industrial-farming practices can leave the land drained, eventually unfit for cultivation. Additionally, these practices may disregard animal welfare and tend to establish an unbridgeable gap between growers and consumers. You don't meet the farmers who grow your food when it's industrial-grown.
In sustainable farming, eggs are free range, beef has no added hormones and grapes are, in almost all cases, pesticide-free. Often, you can even shake the hand that picked those grapes.
The sustainable method is gathering speed as more and more operations, typically small-scale and organic, convert to the more Earth-friendly, animal-friendly, grower-friendly mode of operation. Some people practice sustainable farming in their backyards or community gardens.
