Since the third age refers to our impact on the environment, I spent a while thinking about what my carbon footprint is, and how environmentally conscious I am being. Overall, I believe I'm pretty 'green'. I reduce, reuse, recycle, and rely on my bike and feet to get me places. While I grew up in a household that recycled, and it seems normal to me, it still may be a relatively new idea to some Americans. Ok, maybe a new idea wasn't the write choice of words; but I think it would be a change of lifestyle. According to this article, 23% of Americans don't recycle for various reasons ranging from availability, too much effort, costs, and just plain ignorance.
As far as transportation goes, biking is very popular in Minneapolis. Voted the most bike-friendly state in the nation and boasting more bicyclists than Portland, Minneapolis is greatly reducing its carbon emissions. I make a point to never ride my bike in the winter; 1) because of the cold, 2) because of the damage salt, sand, and ice would have on my already fragile bike, and 3) because its terrifying.
Besides more obvious ways of trying to save our planet, there are other ways that we still take for granted, and most likely don't even think about. Some examples include looking at what chemicals are in the food and products we purchase, the waste we produce, and how far they had to travel to get there. I think its important to point out that even if we believe that we are being green, there is almost always something more we can do to help out our mother.
