What are the consequences of climate change on public health?

The IELTS Reading section can be challenging, requiring a comprehensive understanding of complex texts. Topics related to climate change and public health have become increasingly prevalent in recent years, making them significant for both study and exam preparation. This article will provide an in-depth look at the consequences of climate change on public health, offering a sample IELTS Reading passage along with questions to aid in your preparation. Given the current global focus on climate change, this topic’s resurgence in exams is highly likely, making this practice essential.

IELTS Reading Practice Passage: The Consequences of Climate Change on Public Health

Practice Passage

Climate change, driven by human activities such as fossil fuel combustion and deforestation, poses substantial threats to public health. From infectious diseases to mental health issues, the ramifications are far-reaching and varied.

Rising Temperatures and Heatwaves

Elevated temperatures and frequent heatwaves have become more common, leading to increased instances of heat-related illnesses and deaths. Vulnerable populations, including the elderly and those with pre-existing health conditions, are particularly at risk.

Vector-Borne Diseases

Climate change is altering the distribution of vector-borne diseases. Warmer conditions can expand the habitats of mosquitoes, ticks, and other disease carriers, increasing the spread of illnesses such as malaria, dengue fever, and Lyme disease.

Air Quality and Respiratory Issues

Higher temperatures and shifting weather patterns also impact air quality. Increased levels of pollutants and allergens can exacerbate respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). Wildfires, intensified by prolonged dry periods, release harmful particulates into the air, further degrading air quality.

Waterborne Illnesses

Changes in precipitation and extreme weather events can compromise water quality. Flooding can overwhelm sewage systems, leading to the contamination of drinking water with pathogens and chemicals, resulting in outbreaks of waterborne diseases like cholera and leptospirosis.

Mental Health

The psychological impacts of climate change should not be underestimated. The stress of dealing with extreme weather events, loss of homes, and livelihoods can lead to anxiety, depression, and post-traumatic stress disorder (PTSD).

Food Security and Nutrition

Climate variability affects agricultural productivity, leading to food shortages and malnutrition. Inconsistent weather patterns harm crop yields, and extreme temperatures can reduce the nutritional quality of food.

Inequity and Vulnerability

The health impacts of climate change are disproportionately felt by marginalized and economically disadvantaged communities. These populations often lack the resources to adapt to or recover from climate-related health issues, exacerbating existing health disparities.

Consequences of Rising Temperatures

True/False/Not Given

3. Increased levels of pollutants and allergens can exacerbate respiratory conditions.

   • True
   • False
   • Not Given

4. Climate change has no impact on mental health.

   • True
   • False
   • Not Given

Matching Information

Match the consequences with their descriptions:

• A. Vector-Borne Diseases
• B. Waterborne Illnesses
• C. Food Security and Nutrition

5. Compromising water quality leading to disease outbreaks.
6. Altering disease carrier habitats, spreading illnesses like malaria.
7. Affecting agricultural productivity and leading to malnutrition.

Answer Key and Explanations

1. c. Increased heat-related illnesses and deaths (Explanation: Rising temperatures and heatwaves directly correlate with increased heat-related health issues.)
2. b. Expands habitats, increasing disease spread (Explanation: Warmer conditions enable vectors to thrive in new areas, facilitating the spread of diseases.)
3. True (Explanation: Higher temperatures and weather changes impact air quality, worsening respiratory ailments.)
4. False (Explanation: The passage explicitly states the mental health impacts of climate change.)
5. B (Explanation: Flooding and water contamination lead to waterborne illnesses.)
6. A (Explanation: Climate change alters habitats, affecting the spread of vector-borne diseases.)
7. C (Explanation: Climate variability impacts food security and nutrition through agricultural disruption.)

Common Mistakes

• Misinterpreting the relationship between causes and effects.
• Confusing vector-borne and waterborne diseases.
• Overlooking the mental health impacts due to their less tangible nature.

Vocabulary

• Vector-Borne (adj.): Carried and transmitted by vectors (e.g., mosquitoes) [ˈvɛktər bɔrn]
• Respiratory (adj.): Related to breathing or the lungs [ˈrɛspərətɔːri]
• Agricultural Productivity (n.): Efficiency of crop production [ˌæɡrɪˈkʌltʃərəl ˌproʊdʌkˈtɪvɪti]
• Marginalized (adj.): Treated as insignificant or peripheral [ˈmɑːrʒɪnəlaɪzd]

Grammar Point

Conditional Sentences: Used to express conditions and their possible outcomes.

• If + Present Simple, + Will + Base Verb (e.g., “If temperatures rise, public health will suffer.”)
• Example: “If inadequate measures are taken, climate-induced diseases will spread.”
