Industrialism has taken a heavy toll on the environments where it has become a primary mode of subsistence. The burning of fossil fuels to power factories causes air pollution, particularly the buildup of carbon dioxide and other greenhouse gases in the atmosphere. This has triggered global climate change. Where factories are built next to water sources, local water supplies can become contaminated with dangerous chemicals. Toxic chemicals such as lead can leach into soils, contaminating crops. The clearing of land for mining, logging, ranching, and cash crops leads to habitat loss, causing dramatic reductions in plant and animal biodiversity. Much of this environmental degradation occurs in poorer countries and poor regions of postindustri al countries. As discussed in this chapter, anthropologists in all of the four fields are interested in how people make a living by engaging with their environments, creating systems of production and exchange. Anthropologists also study how such systems create forms of meaning and value as people study, classify, and experiment with the plants, animals, soils, and climate features of their surroundings. With its deep-seated interest in the interdependence of humans and nature, anthropology has been quick to respond to the environmental threats generated by unsustainable modes of subsistence, such as fossil-fuel-driven industrialism and postindustrial hyperconsumption. Practicing “climate ethnography,” many cultural anthropologists have described how previous modes of subsistence have become impossible due to climate change, particularly in “climate sensitive” parts of the world such as deserts and areas at or near sea level (Crate 2011). Contributions to a 2016 book, Anthropology and Climate Change, detail the profound sociocultural effects of climate change in places such as Siberia, Bangladesh, Ethiopia, Papua New Guinea, the Amazon, Peru, Australia, and Alaska (Crate and Nuttall 2016). Anthropologist Jerry Jacka (2016) reports how extreme climate fluctuations are causing droughts, floods, and frosts that threaten local subsistence strategies in Papua New Guinea. In heavily affected areas, horticulture becomes impossible, and people are forced to migrate, sometimes leaving the sick and the elderly behind to die. In areas where people continue to farm, invasive weeds and insects have taken over, destroying crops and firewood. Unpredictable rainfall and flooding cause frequent food shortages when crops fail. Local peoples have responded with a set of strategies to mitigate these changes, such as switching crop species, but horticulture remains a threatened way of life in New Guinea. Similarly, anthropologist Susan Crate’s (2016) work in Siberia shows how cattle keeping is becoming increasingly difficult due to flooded rangelands, unpredictable rainfall, and other unstable climate factors. More and more Siberian young people are abandoning their parents’ way of life and moving to cities in search of wage work. In this chapter, we have surveyed the four main ways of making a living that people have used throughout human history. These four modes of subsistence did not occur in a neat evolutionary sequence, each new one outmoding and replacing the one before. Rather, new strategies were adopted as primary modes of subsistence by some groups and supplementary methods by others. Many groups have experimented with different modes of subsistence, combining them in various ways over time. People change their subsistence strategies in response to population pressures, forced migrations, the spread of new technologies, trade opportunities, and, most recently, global climate change. There is a notable difference between the first three strategies discussed in this chapter and the very last one. Industrialism and postindustrialism are strategies that encompass the world, drawing all other modes of subsistence into the pressures and opportunities of the global capitalist market. As states and corporations seek to gain control over land and natural resources, the modes of subsistence that rely on these resources are threatened. Many people are forced to abandon gathering-hunting, pastoralism, and plant cultivation and the whole ways of life associated with those ways of making a living. There is one more important difference between all previous modes of subsistence and the mode of industrialism/postindustrialism. Gathering-hunting, pastoralism, and plant cultivation are very often (though not always) practiced in ways that sustain and protect the environment. Despite efforts at environmental reform, industrialism and postindustrialism are still practiced in ways that harm and deplete the environment. Perhaps people who practice ecologically smart ways of making a living have lessons to teach those who don’t. Losing these smart ways of making a living would be a cultural tragedy as well as an environmental disaster. Mini-Fieldwork Activity Unstructured Interview Unstructured interviews are a qualitative research method used for research in social sciences and sometimes for interviews for jobs and college entrance. Unstructured interviews are free flowing and are more spontaneous than a planned interview. The goal of this less structured type of interview is to have the interviewee relate information in a more open and neutral environment. Use an unstructured interview method to interview a person about their job. While the interview will be unstructured some light preparation should be done. Think about these questions as you plan your interview. How did the person acquire that job? By choice, convenience, or necessity? Is the job temporary or permanent, and why? What are the challenges of the job? Are there risks or dangers? What are the rewarding features? Does the person get bored? How would the person describe the people they work among? How would they describe their relations with the boss? Are there aspects of unfairness or inequality in the workplace? Does the job allow the person to express creativity? Is the job personally satisfying? Does the person feel free or unfree on the job? What might your interview indicate about work in your society? Reflect on the interview. Was the conversation more relaxed? Did you feel you were able to get sufficient information from your subject? What differences were there in this style of interview from a more formal interview process? How might the information you got be different?
