Human Impact on the Antarctic Food Web Explained

~5 min read

Abstract

This paper examines how human activities have disrupted the Antarctic food web through three interconnected causes: the thinning of the ozone layer, rising global temperatures, and the commercial harvesting of krill. Drawing on scientific assessments, the paper outlines the human behaviors driving these threats — including fossil fuel consumption, deforestation, and industrial pollution — and proposes both global and local remedies. Recommended solutions range from international pollution-reduction agreements and energy reform to stricter krill management regulations and public awareness campaigns. The analysis concludes that protecting Antarctica's unique biodiversity requires coordinated conservation action at every level of governance.

What makes this paper effective

The paper organizes its argument around three clearly defined causes, making a complex environmental problem accessible and logically manageable for the reader.
It scales its recommendations from the global (international pollution policy, renewable energy) down to the specific (local krill regulation), showing practical awareness of how environmental governance operates at multiple levels.
The inclusion of a direct quotation from the Antarctic Krill Conservation Project grounds the advocacy conclusion in an authoritative source, adding credibility to the policy recommendations.

Key academic technique demonstrated

The paper demonstrates effective problem-solution structuring: it first establishes a scientific basis for the problem, then maps causes, and finally proposes tiered solutions. This technique — common in environmental science and policy writing — moves the reader from diagnosis to action in a logical, persuasive sequence.

Structure breakdown

The paper opens with a broad framing of human environmental impact before narrowing to Antarctica. It then identifies three specific threats, explains their human origins, and transitions into two tiers of proposed solutions: a globally integrated policy approach and immediate, Antarctica-specific interventions. The conclusion calls for international awareness and protected-area designations, returning the argument to its global scope.

Introduction: Human Activity and Environmental Harm

Human activities have a generally devastating impact on the surrounding natural environment. The United States alone consumes one third of the world's annual natural resources in a single year. At this rate, the planet would only be able to support human life for an estimated five more decades (Leonard). The irony is that humans do not intend to harm the environment, nor are they always aware of the dangers they create. Relevant examples include the melting of glaciers and the decay of the food web in the Antarctic Ocean. Populations around the world do not realize that their actions impact regions so far away, but the evidence shows that they do.

Three Causes Threatening the Antarctic Food Web

The food web in the Antarctic is suffering severe disruption as a result of three factors, all created by human activity, and none undertaken with the intent to harm the environment. These three causes are:

The harvesting of krill is carried out by commercial fishermen who use it as feed in aquaculture operations. This practice, however, endangers other species that depend on krill as a primary food source, such as baleen whales. In terms of global warming and the thinning of the ozone layer, these phenomena are interconnected: global warming contributes to the thinning of the ozone layer (Naik, 2010). Both are generated by a series of human activities that cause pollution and greenhouse gas emissions.

Drivers of Global Warming and Ozone Depletion

Some of the key human activities driving global warming and the thinning of the ozone layer include:

Conclusion: Conservation at a Global Scale

At the specific level of the Antarctic food web, it is necessary to recognize the problems affecting it and to promote them at a global scale, in order to attract the awareness and support of other groups. In other words, it is pivotal to recognize "that the Antarctic's unique character as the last great wilderness, as home to exceptional concentrations of biodiversity including penguins, whales, and albatrosses, and its critical role in global environmental processes, requires special conservation actions, including but not limited to protected and closed areas" (Antarctic Krill Conservation Project).
