Reading Passage: The Impact of Climate Change on Global Fisheries Productivity

Climate change has emerged as a defining issue of our time, exerting multifaceted impacts on ecosystems globally. Among the sectors most affected are the world’s fisheries, which play a critical role in food security, economic stability, and biodiversity. Changes in temperature, ocean acidity, sea levels, and weather patterns are reshaping fish populations and the productivity of fisheries.

Scientists have observed that rising ocean temperatures are causing a shift in the distribution of marine species. Fish are moving towards the poles, seeking colder waters suited to their physiological requirements. This migration disrupts traditional fishing zones, forcing fishers to venture further afield, often with increased costs and risks. Moreover, species that cannot migrate, such as those limited by habitat specificity, face a heightened risk of decline or extinction.

Ocean acidification, another consequence of increased atmospheric CO2 levels, is impairing the health of coral reefs, which support about 25% of marine life. The acidification process reduces the availability of carbonate ions necessary for the creation of calcium carbonate, which corals and shellfish use to build their skeletons and shells. The degradation of these habitats leads to a decline in biodiversity and fish populations, directly impacting fisheries.

Additionally, rising sea levels and changing weather patterns are altering coastal ecosystems and fish habitats. Coastal fisheries, often reliant on specific environmental conditions, are particularly vulnerable. Flooding, stronger and more frequent storms, and coastal erosion are further complicating fishing activities, infrastructure, and safety.

Economic impacts of these environmental changes are profound. Fisheries contribute significantly to the global economy, providing livelihoods for millions. A decline in fish stocks can lead to reduced catch sizes and higher market prices, subsequently affecting economic stability and food security. Small-scale fishers in developing countries, who lack the resources to adapt to these changes, are especially at risk.

In summary, climate change poses significant threats to global fisheries productivity. Addressing these challenges requires coordinated efforts in climate adaptation, sustainable fishing practices, and conservation initiatives. Increased research and monitoring are essential to understand and mitigate the complex interdependencies between climate change and fisheries. As the situation evolves, so too must our strategies to safeguard these critical resources for future generations.

Questions

Multiple Choice

Q1. What is one of the primary ways climate change is affecting marine life?
A. Increased fish migration towards the poles
B. Decreased atmospheric CO2 levels
C. Reduced sea levels

Q2. Which marine species are most at risk due to habitat specificity?
A. Fish that can migrate easily
B. Species confined to specific habitats
C. Oceanic predators

True/False/Not Given

Q3. Researchers have recorded that fish are moving towards the poles due to changing ocean temperatures.
Q4. Ocean acidification benefits coral reefs and their associated ecosystems.

Matching Information

Q5. Match the following consequences with their effects:

1. Ocean acidification
2. Rising sea levels
3. Changing weather patterns

a. Alters coastal ecosystems and fish habitats
b. Impairs the health of coral reefs
c. Leads to flooding and coastal erosion

Answers and Explanations

Answers

1. A. Increased fish migration towards the poles

2. B. Species confined to specific habitats

3. True

4. False

5. 1 – b, 2 – a, 3 – c

Explanations

1. Increasing ocean temperatures force marine species to seek colder waters, a phenomenon captured in option A.

2. Species restricted to specific habitats, such as coral reefs, face a greater threat compared to migratory species.

3. The passage explicitly mentions that fish are moving towards the poles.

4. Ocean acidification is detrimental to coral reefs, reducing the availability of essential ions for their structure.

• Ocean acidification impairs coral reefs.
• Rising sea levels alter coastal ecosystems.
• Changing weather patterns lead to flooding and erosion.

Common Mistakes and Tips

Common Mistakes:

• Misinterpreting the subtle differences between true/false and not given.
• Confusing different impacts of climate change on fisheries.

Tips:

1. Practice skimming and scanning techniques to identify key information quickly.
2. Familiarize yourself with different question types and practice regularly to enhance accuracy and speed.
3. Understand synoptic relationships between climate change impacts to interpret complex passages effectively.

Vocabulary

• Physiological: pertaining to the functions and activities of living organisms.
• Acidification: process of becoming acidic.
• Carbonate ions: essential chemical ions for the formation of coral skeletons.
• Poles: extreme north or south points of the Earth.
• Biodiversity: variety and variability of life forms within a given ecosystem.

Grammar Focus

Complex Sentences:

• Uses multiple clauses to provide detailed explanations.
  E.g., “Scientists have observed that rising ocean temperatures are causing a shift in the distribution of marine species, forcing fishers to venture further afield.”

Passive Voice:

• Often used in formal writing to emphasize the action rather than the subject.
  E.g., “Ocean acidification, another consequence of increased atmospheric CO2 levels, is impairing the health of coral reefs.”
