We hear these words today; biodiversity, localvores, carbon footprint, self-sufficient living and sustainability. But what do they actually mean, and how important are they for us today?

This is an article written by one of our guest submitters, Jack Lundee, who explains these issues by writing about Gary Nabhan and his unfailing push to get people to not only eat locally, but to also eat what is in season, and to only eat food that has come within a 250 mile radius.

Gary Nabhan is a champion of locally grown food that has been produced using non-genetically modified seeds and supporting heirloom vegetables and heritage animal breeds that are sadly, fast disappearing.

“In other environmental issues we tell people to stop something, reduce their impact, reduce their damage," claims Agriculturist Gary Nabhan. Nabhan is an ethnobotanist whose endorsement of biodiversity has captured the attention of many individuals over the years. Since "Coming Home to Eat" was printed in 2001, the local food movement has caught fire, causing a global green epidemic, along with a fight to match Nabhan’s philosophies.

Nabhan proposes that eating homegrown crops will have a greater impact on sustainability for our planet, ultimately reducing our carbon footprint. Otherwise known as “eat what you conserve," this is a well-established theory in that by eating the fruits and vegetables that we are trying to conserve/save, we’re promoting the granular dissemination of various plant species.

There are many opponents of Nabhan’s theory however. In particular, a lot of scientists are struggling to yield crop from genetically modified seeds. – This is exactly the type of situation that proponents of biodiversity are looking to avoid.

Former President Clinton, Doug Band, and the Clinton Global Initiative (CGI) have supported the International Rice Research Institute (IRRI) on rice seed modification in an effort to create a more sustainable rice crop. This attempt is classified as a direct result of climate change, and the handful of people that support thoughts like this believe that we’re attempting to fix human-created problems.

Recent studies have demonstrated these modified seeds and their ability to fail completely, leaving hundreds of thousands of dollars in crop to waste. Herein lies the argument; most would say that we’re actually creating further problems with genetically altered crops.

Most experienced agriculturists and sustainability experts would agree with Gary Nabhan’s theories on biodiversity, further bearing the notion of eat what you conserve. In fact, well-known agriculturist Marco Contiero portrays Nabhan’s theories quite evidently in boldly stating, “biodiversity is an essential characteristic of any sustainable agricultural system, especially in the context of climate change." Contiero also believes that people should start eating more localized crops, and spending less time shopping for exotic fruits and vegetables.

Nevertheless, both conservationists rely on action-oriented approaches to providing greater sustainability through biodiversity. As eco-conscious individuals, we must all remember to play our role in promoting these same ideas; don’t hesitate to stop by your local farmers market to pick up tomatoes or strawberries. Congruently, be sure to pick up what’s in season and grown locally.
