Ecology and Economics | John Scales Avery

Friday 4 June 2021

by John Scales Avery

A new report published in the Royal Swedish Academy of Sciences’ Ambio, points out that humanity is hurtling towards destruction unless we have the collective wisdom to change course quickly. Here is the link to the article.

The Ambio article was written as part of the preparation for a meeting of Nobel Prize winners to discuss the state of the planet. The virtual meeting will be held later this month.

We must achieve a steady-state economic system

A steady-state economic system is necessary because neither population growth nor economic growth can continue indefinitely on a finite earth. No one can maintain that exponential industrial growth is sustainable in the long run except by refusing to look more than a short distance into the future.

Of course, it is necessary to distinguish between industrial growth, and the growth of culture and knowledge, which can and should continue to grow. Qualitative improvements in human society are possible and desirable, but resource-using and pollution-producing industrial growth is reaching its limits, both because of ecological constraints and because of the exhaustion of petroleum, natural gas, and other non-renewable resources, such as metals. The threat of catastrophic climate change makes it imperative for us to stop using fossil fuels within the next few years.

Entropy is a measure of disorder. Our present economic system is unidirectional and entropic: Low-entropy resources are converted into high-entropy waste, a unidirectional process. By contrast, to be sustainable in the long run, a process must be cyclic, like the growth and regeneration of a forest.

We must decrease economic inequality

In his Apostolic Exhortation, “Evangelii Gaudium” Pope Francis said:

“In our time humanity is experiencing a turning-point in its history, as we can see from the advances being made in so many fields. We can only praise the steps being taken to improve people’s welfare in areas such as health care, education, and communications. At the same time, we have to remember that the majority of our contemporaries are barely living from day to day, with dire consequences. A number of diseases are spreading. The hearts of many people are gripped by fear and desperation, even in the so-called rich countries. The joy of living frequently fades, lack of respect for others and violence are on the rise, and inequality is increasingly evident. It is a struggle to live and, often, to live with precious little dignity.”

Prof. Richard Wilkinson, the social epidemiologist, has documented the ways in which societies with less economic inequality do better than more unequal societies in a number of areas, including increased rates of life expectancy, mathematical performance, literacy, trust, social mobility, together with decreased rates of infant mortality, homicides, imprisonment, teenage births, obesity, and mental illness, as well as drug and alcohol addiction.

We must also remember that according to economist John A. Hobson, the basic problem that led to imperialism was an excessively unequal distribution of incomes in industrialized countries. The result of this unequal distribution was that neither the rich nor the poor could buy back the total output of their society. The incomes of the poor were insufficient, and the rich were too few in number. Thus governments were forced to look for markets in the less developed parts of the world.

We must break the power of corporate greed

When the United Nations was established in 1945, the purpose of the organization was to abolish the institution of war. This goal was built into many of the articles of the UN Charter. Accordingly, throughout the world, many war departments were renamed and became departments of defense. But the very name is a lie. In an age of nuclear threats and counter-threats, populations are by no means protected. Ordinary citizens are just hostages in a game for power and money. It is all about greed.

Why is war continually threatened? Why is Russia threatened? Why is war with Iran threatened? Why fan the flames of conflict with China? Is it to “protect” civilians? Absolutely not! In a thermonuclear war, hundreds of millions of civilians would die horribly everywhere in the world. What is really being protected are the profits of arms manufacturers. As long as there are tensions; as long as there is a threat of war, military budgets are safe; and the profits of arms makers are safe. The people in several “democracies,” for example, the United States, do not rule at the moment. Greed rules.

As Professor Noam Chomsky has pointed out, greed and lack of ethics are built into the structure of corporations. By law, the chief executive officer of a corporation must be entirely motivated by the collective greed of the stockholders. He must maximize profits. If the CEO abandons this single-minded chase after corporate profits for ethical reasons, or for the sake of humanity or the biosphere or the future, he (or she) must, by law, be fired and replaced.

We must leave fossil fuels in the ground

The threat of catastrophic climate change requires prompt and dedicated action by the global community. Unless we very quickly make the transition from fossil fuels to 100% renewable energy, we will reach a tipping point after which uncontrollable feedback loops could take over, leading to a human-caused 6th geological extinction event. This might even be comparable to the Permian-Triassic event, during which 96% of all marine species and 70% of terrestrial vertebrates became extinct.

Arctic sea ice is melting at an increasingly rapid rate, because of several feedback loops. One of these feedback loops, called the albedo effect, is due to the fact that white snow-covered sea ice in the Arctic reflects sunlight, while dark water absorbs it, raising the temperature and leading to more melting.

Another feedback loop is due to the fact that rising temperatures mean that more water is evaporated. The water vapor in the atmosphere acts like greenhouse gas and raises the temperature still further.

If we consider long-term effects, by far the most dangerous of the feedback loops is the melting of methane hydrate crystals and the release of methane into the atmosphere, where its effects as a greenhouse gas are roughly twenty times great as those of CO2.

When organic matter is carried into the oceans by rivers, it decays to form methane. The methane then combines with water to form hydrate crystals, which are stable at the temperatures which currently exist on ocean floors. However, if the temperature rises, the crystals become unstable, and methane gas bubbles up to the surface.

The worrying thing about methane hydrate deposits on ocean floors is the enormous amount of carbon involved: roughly 10,000 gigatons. To put this huge amount into perspective, we can remember that the total amount in world CO2 emissions since 1751 has been only 337 gigatons.

Hope for the future comes from the exponential growth of renewable energy. Governments and banks must aid this growth, and they must end the support that they give to fossil fuel corporations.

Ecological Economics

In the future, ecology must be incorporated into economic theory. The human economy is a part of the global environment, rather than the reverse. Human society cannot prosper while the environment suffers. Economists must acknowledge this fact. We need a new economic system, one that has both a social conscience and an ecological conscience.

(John Scales Avery was born in 1933 in Lebanon, where his father was Professor of Anatomy at the American University of Beirut. He received his training in theoretical physics and theoretical chemistry at M.I.T., the University of Chicago and the University of London. He is the author of numerous books and articles, both on scientific topics and on broader social questions. In 1969 he founded the Journal of Bioenergetics and Biomembranes, and he served as its Managing Editor until 1980. He also served as Technical Advisor to the World Health Organization between 1988 and 1997, and as Chairman of the Danish National Group of Pugwash Conferences on Science and World Affairs between 1990 and the present.)
