I am on Facebook and recently saw a group called: "Zero Emissions Day on September 21." I don't get this. Even if we were dead, we would not be zero emission because our decaying body would emit carbon. Carbon is a natural part of the life process. Our bodies are made of carbon. Every creature, tree, organism has carbon. Carbon is the glue that holds life together. (PBS has a great video series on carbon.) Without carbon there would be on life on this planet. So saying that we want zero emission, isn't possible.
If we are talking about not using transportation or any appliances the create CO2, I guess we can do that for one day, one hour. But it's not a sustainable solution. I don't know many people who are willing to go back to living like cave men.
I like what I read in one article. What we are faced with is a design problem. We designed our environment to conflict with nature. Now we have to go and redesign how we make things, use things, and what we do afterwards with the items. I know that this is oversimplification, but I'm getting sleepy and need to go to sleep. I have a big day tomorrow.
So, yes, I'll try to reduce my carbon footprint on the 21st of September, but I will also try to find ways that will help in small ways, every day.
