Editor,

Only the least informed and most ignorant Homo sapiens on planet Earth today do not understand that we Homo sapiens are responsible for the ongoing changes in Earth’s climate. In simple though real terms, our life habits are adding so much new carbon dioxide to the atmosphere that climate is warming. Yes, some efforts are being made to reduce that amount of new carbon dioxide, but so far these efforts are failing.

For visual evidence of this, just do an internet search for the so-called Keeling Curve. This is a graph of carbon dioxide in the atmosphere that is not just rising with time, but is rising at an ever-increasing rate. The culprit, if you will, is we so-called Homo sapiens, going about our daily lives.

One possible solution to reverse this trend is to simply have people rather drastically change their daily life habits. Another is to somehow reduce the number of Homo sapiens on our planet. This may be even harder to sell. Paul Ehrlich, former biology professor at Stanford University, tried educating us readers about this situation back in the 1960s. I invite you to read his book “The Population Bomb,” published in 1968. It seems to me that some combination of fewer people on planet Earth combined with some changes in human life habits is needed to reduce or stop global climate change.
