The problems that won’t go away

Economic injustice is a matter of human relations.  So is the question of war and peace..  They are matters of how we human beings decide to live with each other.

Other problems, such as population growth, climate change and exhaustion of natural resources, are different.  They are questions of how we human beings relate to an external world that is governed by the laws of physics, chemistry and biology, and not by human desires.

The Union of Concerned Scientists published a series of charts 25 years ago (in 1992) about ominous trends in the external world that affect human survival.   Now scientists have taken another look at these trends.  A couple have gotten better.  Many have gotten worse.

One success is the recovery of the ozone layer, achieved by regulation of ozone-depleting substances.   A great achievement not shown on the chart is elimination of famines and extreme poverty in many parts of the world.

Another is the reduction in the birth rate.  In many nations, it is at or below 2.1 children per couple, the replacement rate.  This was achieved by means of the spread of birth control information and the empowerment and education of women.  But birth rates are still high in some parts of the world and, even if this weren’t true , it would still take a generation or two before world population levels off..

In other ways, things have grown worse since 1992.   The concentration of greenhouse gasses continues to increase.  As a result, average temperatures continue to increase.   Deforestation continues.  There is a continued increase in ocean dead zones, where oxygen depletion kills all fish and aquatic animal life.   This means the world fish catch is declining.

This is a great challenge to humanity because there is very little than can be done that will have any impact in the lifetimes of adults now living.  Can we human beings unite?  Do we care enough about coming generations to put their interests first?  Is there still time to act?  I wish I knew the answers to these questions.
