Reading Passage & Questions

Environmental Medicine

Paragraph A

In simple terms, environmental medicine deals with the interaction between human and animal health and the environment. It concerns the adverse reactions that people have on contact with or exposure to an environmental excitant. Ecological health is its primary concern, especially emerging infectious diseases and pathogens from insects, plants and vertebrate animals.

Paragraph B

Practitioners of environmental medicine work in teams involving many other specialists. As well as doctors, clinicians and medical researchers, there may be marine and climate biologists, toxicologists, veterinarians, geospatial and landscape analysts, even political scientists and economists. This is a very broad approach to the rather simple concept that there are causes for all illnesses, and that what we eat and drink or encounter in our surroundings has a direct impact on our health.

Paragraph C

Central to environmental medicine is the total load theory developed by the clinical ecologist Theron Randolph, who postulated that illness occurs when the body’s ability to detoxify environmental excitants has reached its capacity. His wide-ranging perception of what makes up those stimuli includes chemical, physical, biological and psychosocial factors. If a person with numerous and/or chronic exposures to environmental chemicals suffers a psychological upset, for example, this could overburden his immune system and result in actual physical illness. In other words, disease is the product of multiple factors.

Paragraph D

Another Randolph concept is that of individual susceptibility or the variability in the response of individuals to toxic agents. Individuals may be susceptible to any number of excitants but those exposed to the same risk factors do not necessarily develop the same disease, due in large part to genetic predisposition; however, age, gender, nutrition, emotional or physical stress, as well as the particular infectious agents or chemicals and intensity of exposure, all contribute.

Paragraph E

Adaptation is defined as the ability of an organism to adjust to gradually changing circumstances of its existence, to survive and be successful in a particular environment. Dr Randolph suggested that our bodies, designed for the Stone Age, have not quite caught up with the modern age and consequently, many people suffer diseases from maladaptation, or an inability to deal with some of the new substances that are now part of our environment. He asserted that this could cause exhaustion, irritability, depression, confusion and behavioural problems in children. Numerous traditional medical practitioners, however, are very sceptical of these assertions.

Paragraph F

Looking at the environment and health together is a way of making distant and nebulous notions, such as global warming, more immediate and important. Even a slight rise in temperature, which the world is already experiencing, has immediate effects. Mosquitoes can expand their range and feed on different migratory birds than usual, resulting in these birds transferring a disease into other countries. Suburban sprawl is seen as more than a socioeconomic problem for it brings an immediate imbalance to the rural ecosystem, increasing population density so people come into closer contact with disease-carrying rodents or other animals. Deforestation also displaces feral animals that may then infect domesticated animals, which enter the food chain and transmit the disease to people. These kinds of connections are fundamental to environmental medicine and the threat of zoonotic disease looms larger.

Paragraph G

Zoonoses, diseases of animals transmissible to humans, are a huge concern. Different types of pathogens, including bacteria, viruses, fungi and parasites, cause zoonoses. Every year, millions of people worldwide get sick because of foodborne bacteria such as salmonella and campylobacter, which cause fever, diarrhoea and abdominal pain. Tens of thousands of people die from the rabies virus after being bitten by rabid animals like dogs and bats. Viral zoonoses like avian influenza (bird flu), swine flu (H1N1 virus) and Ebola are on the increase with more frequent, often uncontainable, outbreaks. Some animals (particularly domestic pets) pass on fungal infections to humans. Parasitic infection usually occurs when people come into contact with food or water contaminated by animals that are infected with parasites like cryptosporidium, trichinella, or worms.

Paragraph H

As the human population of the planet increases, encroaching further on animal domains and causing ecological change, inter-professional cooperation is crucial to meet the challenges of dealing with the effects of climate change, emergent cross-species pathogens, rising toxicity in air, water and soil, and uncontrolled development and urbanisation. This can only happen if additional government funds are channelled into the study and practice of environmental medicine.

Detailed Translation

Paragraph A: Simply put, environmental medicine deals with the interaction between human health, animal health, and the environment. It concerns the adverse reactions people experience when coming into contact with or being exposed to an environmental excitant. Ecological health is its primary focus, especially regarding emerging infectious diseases and pathogens originating from insects, plants, and vertebrate animals.

Paragraph B: Practitioners of environmental medicine work in teams that include many other specialists. In addition to doctors, clinicians, and medical researchers, these teams may include marine and climate biologists, toxicologists, veterinarians, geospatial and landscape analysts, and even political scientists and economists. This represents a very broad approach to the rather simple concept that all illnesses have causes, and that what we eat, drink, or encounter in our surroundings has a direct impact on our health.

Paragraph C: Central to environmental medicine is the “total load theory” developed by clinical ecologist Theron Randolph, who postulated that illness occurs when the body’s ability to detoxify environmental excitants reaches its limit. His broad perception of what constitutes these stimuli includes chemical, physical, biological, and psychosocial factors. For example, if a person with chronic or frequent exposure to environmental chemicals suffers a psychological upset, this could overload their immune system and result in actual physical illness. In other words, disease is the product of multiple factors.

Paragraph D: Another of Randolph’s concepts is “individual susceptibility,” or the variability in how individuals respond to toxic agents. People may be susceptible to any number of excitants, but those exposed to the same risk factors do not necessarily develop the same disease, largely due to genetic predisposition. However, age, gender, nutrition, emotional or physical stress, as well as specific infectious agents or chemicals and the intensity of exposure, all play a role.

Paragraph E: Adaptation is defined as an organism’s ability to adjust to the gradually changing circumstances of its existence in order to survive and thrive in a particular environment. Dr. Randolph suggested that our bodies, designed for the Stone Age, have not quite caught up with the modern era; consequently, many people suffer from diseases caused by maladaptation—an inability to cope with some of the new substances now present in our environment. He asserted that this could cause exhaustion, irritability, depression, confusion, and behavioral problems in children. However, many traditional medical practitioners remain highly skeptical of these claims.

Paragraph F: Examining the environment and health together is a way to make distant and nebulous notions, such as global warming, feel more immediate and significant. Even a slight rise in temperature, which the world is already experiencing, has immediate effects. Mosquitoes can expand their range and feed on different migratory birds than usual, leading these birds to transfer diseases to other countries. Suburban sprawl is viewed as more than just a socioeconomic problem, as it creates an immediate imbalance in the rural ecosystem, increasing population density and bringing people into closer contact with disease-carrying rodents or other animals. Deforestation also displaces wild animals, which may then infect domesticated animals; these animals then enter the food chain and transmit diseases to humans. These connections are fundamental to environmental medicine, and the threat of zoonotic disease is looming ever larger.

Paragraph G: Zoonoses—diseases transmissible from animals to humans—are a major concern. Various types of pathogens, including bacteria, viruses, fungi, and parasites, cause zoonoses. Every year, millions of people worldwide fall ill due to foodborne bacteria such as salmonella and campylobacter. Tens of thousands die from the rabies virus after being bitten by rabid animals. Viral zoonoses like avian influenza (bird flu), swine flu (H1N1), and Ebola are on the rise, with more frequent and often uncontainable outbreaks.

Paragraph H: As the human population grows, encroaching further into animal habitats and causing ecological change, inter-professional cooperation is crucial to meet the challenges of climate change, emerging cross-species pathogens, rising toxicity in our air, water, and soil, and uncontrolled development and urbanization. This can only be achieved if additional government funds are channeled into the study and practice of environmental medicine.
