The Social Responsibility of Scientists
THE SOCIAL RESPONSIBILITY OF SCIENTISTS John Scales Avery May 23, 2021 INTRODUCTION1 Three major threats to human society Science and technology have conferred many benefits on human society, but as we start the 21st century, most thoughtful observers believe that our science-driven and information-driven industrial civilization has entered a period of crisis. All indices are increasing rapidly - population, total wealth, industrial output, rates of scientific discovery, and so on. But it is clear that the total human footprint on the face of nature has become too great. A sixth mass extinction of plants and animals is already in progress, Insects are disappearing, and with them, birds. Tropical rain-forests are being lost at an alarming rate. Ice loss at both poles is increasing. Temperatures worldwide are rising at an accelerating rate because of greenhouse gas emissions. There is a great danger that if immediate and drastic action is not taken, feedback loops will be initiated which will make human efforts to prevent climate change useless. Thus there is a threat of an ecological megacatastrophe, of which catastrophic climate change is a part. Another serious threat comes from nuclear war. Despite the Treaty on the Prohibition of Nuclear Weapons, which makes them illegal, the nuclear powers retain their weapons and even spend enormous amounts of money “modernizing” them. A third threat is an extremely widespread famine, which could occur by the middle of the 21st century from a combination of population growth, climate change and the end of the fossil fuel era. Catastrophic climate change A major problem with mobilizing the political will needed to take strong action to prevent the catastrophe is a contrast between time-scales.
