Some of the most vocal opponents of environmentalism and climate change in the US are politically Conservative Christians. They object to it, not just on the grounds that they believe it to be wrong scientifically, but also because they are highly suspicious of it on political and religious grounds. It is argued that the Green movement is really a pagan movement, or else a way of sneaking Socialism in through the back door through stressing the need for legislation and the regulation of industry to protect the environment. It’s also denounced as a form of Nazism, because the Nazis were also eager to protect the German environment.
It’s true that Green politics has strongly influenced some contemporary neo-Pagan religious movements, particularly Wicca, whose deities consist of an Earth mother and horned god. However, the scientific evidence on which the Green movement is based is separate and independent from any one particular religious or political group. And modern Green politics began with books such as Silent Spring in the 1960s and the Club of Rome, a gathering of concerned scientists, in the early ’70s, and not with Hitler and the Nazis.
Furthermore, writers and philosophers long before the Nazis were also acutely concerned with the threat of overpopulation and the damage humans were doing to the environment. One of them was the early Christian apologist, Tertullian, who wrote
‘Most convincing as evidence of populousness, we have become a burden to the Earth. The fruits of nature hardly suffice to sustain us, and there is a general pressure of scarcity giving rise to complaints. Need we be astonished that plague and famine, warfare and earthquake, come to be regarded as remedies, serving to prune the superfluity of population?’
This quotation was dug up by Adrian Berry, a fellow of the Interplanetary Society, Royal Astronomical Society and Royal Geographical Society. Berry is very much a man of the right, who used to write for the Torygraph. He used it to argue that people have always had exaggerated fears about the threat to society. Or alternatively, they could also be extremely complacent, such as the 2nd century AD Roman writer Pliny. Pliny wrote of the enduring splendor of the Roman Empire just before it began to collapse. Jonathan Margolis also cites in his chapter on predictions of environmental catastrophe, ‘Global Warning’, in his A Brief History of Tomorrow: The Future, Past and Present (London: Bloomsbury 2000) 89, where he also discusses the possibility that predictions of environmental collapse may be wrong.
At the moment, the majority of the world’s scientists are convinced that climate change and environmental damage caused by humanity are real, and a genuine threat to the planet, its flora and fauna, and ultimately humanity itself. Furthermore, archaeologists become increasingly aware how global changes to the environment have caused civilizations to collapse. The early Viking colonies in Greenland were destroyed in the 14th century, when the environment in the northern hemisphere became colder, making it impossible to practice European-style agriculture so far north.
Similarly, the highly developed Pueblo Indian cultures in the Chaco canyon in what is now the southwestern US collapsed and were abandoned when the climate became hostile in the 13th century. The cultures existed in an arid region of the US, using extensive irrigation canals to water their crops. The area suffered an intense drought, and unable to support themselves, the inhabitants moved away.
As for ancient Rome, one of the causes for the barbarian invasions may well have been climate change. The environment became colder from the 3rd century onwards. Central Asian tribes, such as the Huns, moved west, crossing the steppes into Europe and moving south to attack China. This displaced other tribes, such as Goths, who were settled around the Black Sea. The sea levels began to rise, so that the Frisians and other Germanic tribes settled in what is now the Netherlands, were forced to abandon low-lying farms and villages on the coasts. This may have been one of the causes of the Anglo-Saxon migrations to Britain.
In the Greek-speaking eastern Roman Empire, towns shrank, while in the west there was a movement away from the cities, partly through economic grounds. Historians have argued whether the Roman population was decimated by disease. Certainly in Rome itself, located amidst swampland, malaria was endemic, and the sheer size of the population meant that it was periodically subject to outbreaks of other diseases. And the city depended on a steady influx of new immigrants to replenish its population. And there was a constant threat of starvation. The free Roman masses depended on shipments of grain from Egypt and north Africa, and one of the elected officials in the city was responsible for securing the grain supply. Amongst the graffiti found scrawled on walls in Pompeii are election slogans urging men to vote for a particular candidate because ‘he gets good bread’.
Tertullian may well have been absolutely right about the dangers of overpopulation. And regardless of whether he was or wasn’t, the fact that he, one of the great defenders of Christian faith and doctrine in the Roman Empire, was prepared to accept and argue that overpopulation and environmental damage were a danger, shows that there is nothing inherently anti-Christian in the Green movement. This was shown a few weeks ago when the current pope, Pope Francis, criticized Trump’s government for ignoring science and failing to tackle climate change. There’s an irony here in a religious figure attacking the elected leader of a supposedly secular state for having an anti-scientific attitude. And it remains true that there is nothing fundamentally contrary to Christianity about Green politics regardless of the support for Green politics amongst peoples of other religions or none.
