What we have now in the U.S. and most parts of the world is a lot of interest and ideas on how to address our carbon footprint to reduce global warming. While we cannot dictate to the rest of the world what we think needs to be done, we can certainly lead by example if we want to take those necessary steps. It seems to me that if we look where we should be in the future, we need to start coming together now and discuss the best ways to move forward. These are difficult issues potentially impacting all of our lives.
