I try to be green.
Like tengu most of my choices are due to econonics. Quite a bit of stuff that is labeled eco-frendly is just marketing of a premium product, sold at high prices. The easiest way for the average bushcrafter to lower their carbon footprint is quite simply to make their own kit, and interact with our local environment. We don't need to do expensive courses in the sweden to be experts, or buy hand knitted wooly hats form a sammi tribes woman to look the part. Recycling that shunk tatty jumper into a good pair mittens, buying a 40 year old wool blanket from oxfam to make a bushcrafters top is far better for the environment than something that is made from organic llama from a commune in montana. Some kit like waterproofs finding the greenest affordable opition that works is very difficult (please prove me wrong).
Those of us that are into wild food, know there is nothing better than food that was a part of ecosystem three hours ago and is now on your plate. No plastic wrapping, no being shipped up and down the country in trucks, just a short a walk, or car ride, to get to your plate.
