What Is the Author’s Purpose in Save the Coral Reefs?

The author’s purpose in “Save the Coral Reefs” is to persuade readers that coral reefs face serious, escalating threats and that urgent action is needed to protect them. The text uses a combination of scientific evidence, emotional appeals, and practical recommendations to convince the audience that coral reef conservation matters, both ecologically and economically. While the piece informs readers about the dangers reefs face, the deeper goal is to move people from awareness to action.

Persuasion Through Scientific Evidence

The most prominent strategy in the text is building a logical case for why coral reefs need saving. The author presents concrete data about the threats reefs face: rising ocean temperatures, ocean acidification, overfishing, destructive fishing techniques, coastal development, and pollution. These aren’t vague warnings. The text connects them to measurable outcomes like coral bleaching, where overheated corals expel the algae they depend on and turn white.

The scale of the problem is central to the argument. Tropical ocean temperatures have risen by 0.1°C over the past century, which sounds small but has triggered bleaching events stretching across thousands of square miles. Oceans absorb roughly 22 million tons of carbon dioxide every day, driving acidification levels higher than anything reefs have experienced in the last 400,000 years. That acidity reduces the water’s ability to carry the calcium carbonate corals need to build their skeletons. By grounding the argument in specific, verifiable numbers, the author establishes credibility and makes the urgency feel real rather than abstract.

Why the Author Chose to Inform and Persuade

A purely informational text would lay out facts and stop there. “Save the Coral Reefs” goes further by framing those facts within a clear argument: these ecosystems are valuable, they are deteriorating, and people can do something about it. This dual purpose, informing while persuading, is deliberate. The author recognizes that most readers don’t already understand how coral reefs function or why their decline matters to people who live nowhere near the ocean.

To bridge that gap, the text emphasizes the economic value of reefs. U.S. coral reefs alone contribute an estimated $3.4 billion per year through services like flood protection, fisheries, and tourism. Globally, reefs shield coastlines from storm surges and support the livelihoods of hundreds of millions of people. By translating ecological loss into dollars and jobs, the author makes the stakes personal for readers who might not otherwise connect with marine conservation. This is a classic persuasive move: showing that the problem affects the reader’s world, not just a distant underwater one.

Emotional Appeals to Create Urgency

Beyond the data, the text uses emotional language to make readers feel the weight of what’s being lost. Descriptions of bleached, dying reefs are meant to provoke concern and even grief. This approach mirrors a well-known strategy in coral reef advocacy. Marine biologist Kristen Marhaver, in a widely referenced talk on the subject, described the first time she cried underwater after witnessing reef damage, a moment that resonated with audiences because it transformed statistics into human experience.

The author of “Save the Coral Reefs” similarly uses vivid, accessible language to make destruction feel immediate. Phrases describing reefs as ancient ecosystems that survived the extinction of the dinosaurs serve a dual purpose: they establish the resilience of coral over geological time while highlighting how alarming it is that modern threats are overwhelming them. If something survived millions of years of natural disasters but is now dying because of human activity, that contrast carries emotional force without needing to overstate the case.

A Call to Action, Not Just Awareness

The clearest signal that the author’s purpose is persuasion, not just information, is the text’s structure. It doesn’t end with a summary of problems. It moves toward solutions and asks the reader to engage. The author encourages specific behaviors: reducing carbon footprints, supporting sustainable fishing practices, being mindful of reef-safe products, and advocating for policies that address climate change.

This structure follows a classic persuasive format. First, establish the problem (reefs are dying). Then, explain why it matters (ecological and economic consequences). Finally, offer a path forward (individual and collective action). The title itself, “Save the Coral Reefs,” functions as an imperative statement. It’s a command, not a description. That word choice signals the author’s intent before the reader even begins the first paragraph.

How the Threats Build the Author’s Argument

The text layers multiple categories of threats to create a sense of compounding danger. Natural events like hurricanes and El Niño patterns have always stressed reefs, but the author argues that human-caused threats are pushing reefs past their ability to recover. Overfishing removes herbivorous fish that keep seaweed from smothering coral. Coastal development and agricultural runoff pour excess nutrients and sediment into reef waters. Careless tourism physically damages fragile structures. Each of these would be manageable in isolation, but the author’s point is that they don’t occur in isolation.

Climate change ties them all together. Warming seas trigger bleaching events, and acidification weakens coral skeletons. Together, they lower the threshold at which corals bleach, meaning even small additional stressors become catastrophic. NOAA confirmed in April 2024 that the world is in its fourth global coral bleaching event, the largest on record. Since January 2023, bleaching-level heat stress has affected roughly 84% of the world’s coral reef area, with mass bleaching documented in at least 83 countries. Conservative projections suggest mass bleaching could become an annual event on most reefs by 2050. The author uses this cascading logic to argue that half-measures won’t work: only systemic changes, particularly reducing carbon emissions, will give reefs a chance to survive.

The Intended Audience Shapes the Purpose

The text is written for a general audience, including students and everyday readers, not marine biologists or policymakers. This choice shapes everything about how the author builds the argument. Technical terms are explained rather than assumed. Economic impacts are framed in relatable terms. The emotional appeals are accessible, relying on imagery and storytelling rather than academic analysis.

By targeting a broad audience, the author maximizes the persuasive reach of the text. A specialist already knows reefs are in trouble. The general public, in many cases, does not fully grasp the scale or the personal relevance of reef loss. The author’s purpose is to close that gap: to take readers from “I’ve heard coral reefs are important” to “I understand why, and I know what I can do about it.” That transformation, from passive awareness to informed concern, is the core objective of the text.
