The geese in the above picture know that they have to keep changing the leader in order to preserve the stamina of the entire flock.
People have polluted the atmosphere with carbon by wastefully burning carbon-based fuels. Even those who accepted climate change didn’t worry about a few degrees increase in temperature; but they didn’t realize that major shifts in extreme weather patterns comes along with small increases in the global average temperature. It may already be too late to keep things as they are, even if we change now. We should have changed much earlier to keep the weather patterns of old.
Many cultures and governments are currently learning that they have to change to keep things the way they were. We have collectively moved toward global commerce and now some wonder if that was the right way to go. Is it too late to make the changes necessary to preserve the cultures of old?
If I want to keep things photographically as they are, I will have to make some changes. If I hope to keep walking and carrying a camera I have to make changes. I have been assuming that the pain in my knees was due to arthritis, but I just learned that I have no sign of arthritis in my knees according to recent x-rays that I had. It is my back that is pinching the nerves to my legs and creating my balance problems and pain in the knees. Hopefully I won’t have to have more surgery. I had one lumbar fusion in 2010 because of this problem.
