Three dominant environmental threats are identified: climate change, mass extinction, and pestilence. The warming of the planet is accelerating. At the same time, species are becoming extinct at a startling rate. Newly emerging infectious diseases—COVID-19 being the latest off the production line—are becoming more pronounced and problematic. It is argued that our habit of eating animals—and the massive reallocation of biomass that it involves—lies at the heart of all of all three problems, and if we abandon this habit, we can make substantial progress in tackling them. This proposal should be taken seriously on the grounds that it is easier to implement, more effective once implemented, and ultimately more palatable than other options.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122099856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This energy comes in two forms: fuel and food. These are continuous: they are both means of energy acquisition consumed for the same purpose, the maintenance of a complex society. The energy sources that sustain a society—whether fuel or food—must have a sufficiently high aggregate energy returned on energy invested (EROI). The EROI of a source is the energy acquired from a source divided by the energy that the society had to invest in acquiring it. Once the EROI of a society’s energy sources drops below a certain threshold, societal collapse often results: the breakup of that society and the emergence of new, simpler societies. Calculations suggest that maintenance of a society recognizably similar to our own vis-à-vis socioeconomic parameters requires energy sources with EROIs in the 11–14 range. Maintenance of certain markers of liberal democracies may require higher EROIs, in the 20–30 range.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115934274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon capture and sequestration technologies currently do not work on an industrial scale, and even if they could be made to work, they will reduce the energy returned on energy invested (EROI) of fossil fuels to below acceptable levels. The EROI of nuclear fission is disputed, but most peer-reviewed work places it in the 5–14 range, making it of questionable utility. Nuclear fusion, if it works, will not be available in time. Some renewable sources—notably, various biofuels—have unacceptably low EROIs. The remaining forms of renewable energy—solar, wind, hydropower, and wave power—sport EROIs that are, at best, on the cusp of viability. There is reasonable hope for improvement in these technologies because they are, at present, immature. In the meantime, it would be ideal if we could find a way to give them an edge.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128069862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One consequence of the inverted energy returned on energy invested (EROI) of meat is that we use far more land for farming than we would need if our diet were to be exclusively plant based. In the United States alone, somewhere in the region of 834 million acres could be made available through this strategy, much of it suitable for afforestation. Even the afforestation of land not currently used for farming has the potential to reduce global carbon dioxide emissions by nearly one-third. Adding in land currently dedicated to animal grazing and feed crops is a potentially game-changing development in the fight against climate change.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121494559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of temperate diseases, almost all tropical diseases, and probably all newly emerging infectious diseases are zoonoses or they have zoonotic origins. A zoonotic pathogen can go through five stages, in which it transforms from one that afflicts only nonhuman species to one that is exclusively human. There are several factors that determine the likelihood of such a transformation. The most important of these, since it is most under our control, is the frequency of encounters between us and the animal reservoir. Eating animals and disturbing their environment are the two forms of human behavior most likely to increase frequency of encounters. Moreover, most disturbance of the environment is caused by expansion in animal agriculture. Eating animals, therefore, is the most important cause of zoonotic diseases.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132920240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To mitigate these threats, the most important things we can do are (1) stop eating animals and their products and (2) afforest wherever and whenever we can. The first course of action makes possible the second. By no longer eating animals, we make available large areas of land suitable for afforestation. These twin policies will go a long way toward solving our three environmental threats. Afforested land will sequester significant amounts of carbon dioxide, arrest the changes in land use that are the most important cause of extinction, and provide a suitably undisturbed home for animal reservoirs of disease. In afforesting the land, we must let the past be our guide: restore the land to what it was before humans arrived and ruined the neighborhood.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126016759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It will also mitigate current species extinction trajectories. This chapter looks at the history of human-caused extinctions. A great extinction occurs when a percentage of a species dies out (e.g., 75%). A mass extinction occurs when the actual rate of extinction exceeds the normal background rate by a certain margin (e.g., 1000×). There are good reasons for thinking that a mass extinction of species is currently occurring. Humans are the cause of this, as they have been the cause of all major extinction pulses since the Quaternary period. This chapter examines one of the Quaternary extinction pulses of 8000–11,500 years ago and defends the hominin paleobiogeography hypothesis, that is, that humans were substantially responsible for this pulse of extinctions. An undue focus on extinction, however, can mask the harm we are currently doing to species.","PeriodicalId":212028,"journal":{"name":"World on Fire","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131422473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
