Changing Climate Change

Leaders from 192 nations are gathered in Copenhagen for what has been called "the largest and most important UN climate change conference in history." Certainly the stakes are high. And the science is telling us dramatic action must be taken to prevent the worst effects of a warming globe. The worst, because the climate change ball is already in motion...

What does this have to do with nutrition? A whole heck of a lot it turns out.

Agriculture is a major contributor to greenhouse gas emissions. The livestock sector alone accounts for 18% of global greenhouse gas emissions- more than transportation- according to the FAO.

Climate change is also a public health issue. "The Environmental Protection Agency has concluded greenhouse gases are endangering people's health and must be regulated."

And as the effects of climate change become more drastic, we won't have a choice in rethinking the way we feed ourselves- plant hardiness zone changes, drought patterns, flood impacts, and more are already shifting the way we are able to grow food.

National Public Radio's Marketplace has been airing a series recently called the Climate Race with a companion web portal in which you can listen to the series and explore an interactive US Climate Change map (compiled by the US Global Research Program.) Open the map on the region you live and you'll find effects of climate change that are already occurring and what we can expect by the end of the century if the pattern continues. The Midwest region has already seen two record breaking floods in the past 15 years (many of our local farmers were impacted.) If that isn't scary enough the forecast shows, "Great Lakes water levels to fall 1 to 2 feet by century's end, depending on emission levels." The Great Lakes-- our greatest supply of fresh water. The fresh water situation in other parts of the country looks even more grim.

These are just some of the reasons that so much is at stake in Copenhagen right now. Rising sea levels, already affecting countries like Maldives, will also dramatically change the way we live. Sweeping change is only possible if leaders around the world agree to reduce our collective impact. (And unfortunately, the popular cap and trade solution seems to only switch the pieces on the chess board.) But as individuals, I believe we have some power to create change as well.

Choosing a "low-carbon" diet is one way to reduce your personal carbon footprint. Locally grown foods tend to be lower impact- both in transportation cost, but also, importantly, in processing and packaging costs. Fortunately, the side effects of increased consumption of local foods could turn out to be stronger communities and healthier people. Check out the Center for Food Safety's Cool Food Campaign for more tips on stopping global warming with the food we eat.

Sustainable Nutrition Bottom-line: Our food choices impact the world around us. Less meat, more local, less processed, more home made.... you get the drift. While global politicians continue their politicking, we can choose to reduce our own impact while building the resilience of our communities. Maybe, just maybe, our choices will help our voices trickle up to our leaders.
