No. The current monocultural system relies on petroleum or other non-renewable resources for machinery, chemicals used in fertilizers and pesticides, and transportation to distributors and super markets. On average a meal travels 1500 miles and 7 to 10 calories of energy are used to produce every 1 calorie we eat.
Furthermore because crops are raised in a monocultural system, which is not how plants grow in nature, local pollinators can’t exist because they need nectar year-round. What happens then is millions of beehives are trucked hundreds to thousands of miles so that the bees can pollinate nearly every fruit and vegetable we eat. However this process stresses the bees out and contributes to lowering their immune system along with several other things that are happening in modern day agriculture which have contributed to CCD and the disappearance/die-off of the bees. Currently the U.S. has to import millions of bees from Australia just pollinate
its crops. Check out the documentary The Vanishing of the Bees and some of PEak Oil educator Richard Heinberg’s books for more information about why our current agricultural system is not sustainable.
Like americalibre mentioned, one of the biggest reasons why our agricultural system isn’t sustainable at the moment is due to the long distance the crops travel. This requires a lot of gas and transportation costs, which aren’t healthy for the environment. A better solution would be to encourage local growers and farmers markets. They are a great way to eat healthy and support green living!
