I spoke last night (and am speaking again tonight) to the best and brightest students in North Carolina who are attending a state funded summer program on two North Carolina campuses. To say that the experience has been (and I'm assuming will continue to be) overwhelming is a complete understatement. The reception that I received, their open minded approach and the intelligence I saw in these students gives me great hope. The Governor's School is truly shaping tomorrows leaders and I just wanted to throw a shout out to the incredible minds that I have been encountering and continue to encounter while here.
While the students have impressed me to no end, the faculty is equally if not more impressive! In the short time that I have been here I have seen a level of commitment that is fairly unparalleled. These are the bright minds that should be molding our future and it is my hope that they continue to do what they are doing for a long time coming. These are the folks that are doing it right!
Every state should have a program like this and every young mind should be challenged the way these kids are being challenged - to think, to explore, and to continue learning and evolving.
Thank you to everyone who has made my experience memorable.....you inspire me.

P.S. Ironically, the reason that I am here in the first place is because of Katherine T., a teacher who asked me come to speak to her class in California last year. One of her students who heard me speak sent me one of the greatest letter I have ever received, so I'm glad I was able to return the favor.

The Secret Life of T-shirts
I found this really good write up about what goes into the making of an average t-shirt at emagazine.com. It's quite the eye opener.

COMMENTARY: The Secret Life of T-Shirts
The Toxic Legacy of Conventional Cotton Clothing, and Why You Should Seek Alternatives
By Brian Clark Howard
The conventional cotton in most T-shirts is responsible for 25% of the world’s pesticide use.
Whether you got it at a rock show, thrift store, vacation spot or trendy boutique, chances are you own a favorite, well-worn T-shirt. Soft, comfortable and cool, the tee is the ultimate laid-back attire, but can just as easily be dressed up with a sports coat or simple skirt and accessories. But there’s more to the T-shirt than wearability—the wardrobe staple leaves behind a serious environmental impact.

Whether you got it at a rock show, thrift store, vacation spot or trendy boutique, chances are you own a favorite, well-worn T-shirt. Soft, comfortable and cool, the tee is the ultimate laid-back attire, but can just as easily be dressed up with a sports coat or simple skirt and accessories. But there’s more to the T-shirt than wearability—the wardrobe staple leaves behind a serious environmental impact.
Toxic Fields
Most T-shirts are made of cotton, or at least a cotton blend. Unfortunately, the fabric of our lives has a huge impact on the environment and workers' health. Conventionally grown cotton occupies only 3% of the world's farmland, but uses 25% of the world's chemical pesticides. In the U.S., which produces cotton on 1% of agricultural land, 10% of all agricultural chemicals are used on the crop. A 2000 U.S. Department of Agriculture study found that eighty-four million pounds of pesticides were sprayed on cotton in the U.S., ranking it second behind corn. Seven of the top 15 pesticides used on cotton are considered "likely" or "known" human carcinogens by the Environmental Protection Agency.
And it's not just pesticides. Conventional cotton farmers also use heavy inputs of synthetic, petroleum-derived fertilizers, soil additives, defoliants and other substances, which affect soil, water, air and living things for years to come. Further, 75% of the conventional cotton grown is now genetically modified, a fact that worries critics of the technology, who fear it could contaminate natural organisms and lead to super pests.
Processing
After harvesting, cotton is often treated with chlorine bleach to whiten it. Not only is chlorine toxic at acute doses, but it can also be a skin and lung irritant at lower concentrations. The fabric is also frequently treated with formaldehyde resins—often to render it "easy care”—another highly toxic chemical.
Traditionally, colors are created with dyes that may contain heavy metals, such as chromium copper. Even some so-called “natural dyes” can be mixed with heavy metals to prolong their color.
Printing
If you made T-shirts in art class, chances are you used screen printing. Although there are less-toxic screen printing techniques available today, most major operations rely on the old methods—including an ink called plastisol, a variation of the toxic-to-produce polyvinyl chloride (PVC).
Discharge printing is faster and produces more vibrant colors, but often uses toxic chemicals as well. For example, zinc formaldehyde sulfoxylate (ZFP) is often used to print light colors onto a dark shirt. But again that includes formaldehyde, a known carcinogen. Some people have even gone so far as to suggest that it might not be a good idea to wear such shirts to sleep or while working out.
Shipping
Our economy is global, and so are our T-shirts. Much of today's cotton is grown in the Middle East and India, yet garments are most commonly made in East Asia. Finished products are typically shipped from China and elsewhere to North America and other markets. That results in a substantial use of fuel (often the very dirty stuff burned by container ships), not to mention release of greenhouse gases, particulates and other pollutants.
Plus, it's not uncommon for shipping companies to spray fabrics with insecticides in transit.
Buy Local, Buy Organic
You can help decrease the footprint of your wardrobe, and still look great, by buying locally produced goods, especially stuff made from fibers sourced in your region. Yes, it can help to buy American, although as the above notes sometimes only part of the entire process happens domestically.
It's always a good idea to buy used clothes, or swap things with friends, family or even strangers (swap meets can also be a lot of fun). Used clothes already exist—they don’t consume energy during growing, production and distribution like new clothes—so their overall carbon footprint is a lot less.
You can also find an increasing selection of clothes made from organic cotton, or alternative fibers like bamboo, hemp or recycled materials. These greener goods keep coming down in price, and in many cases are cost competitive with all but the very cheapest, low-quality duds.
Organic cotton, in particular, is grown without synthetic pesticides and herbicides, using techniques that replenish and maintain soil fertility and biodiversity. By buying third-party certified organic, you have greater assurance that the product is produced with genuine sustainability in mind. In the U.S., no genetically engineered materials are allowed in organic products.
The good news is that the farming of organic cotton has been on the rise. That segment increased 152% during the 2007-2008 crop year, according to the Organic Cotton Farm and Fiber Report 2008 by Organic Exchange. Next time you’re shopping for a new favorite tee, look for the organic label.
