Management and Protection of Cold Environments

The Conflict Between Development and Conservation

Oil and gas account for 90% of Alaska's state taxes and provide jobs for 1 in 7 residents. However, extracting this wealth poses a catastrophic threat to a delicate environment.

• This conflict creates a vital need for sustainable management—development that meets current needs without compromising the ability of future generations to meet theirs.
• The 1989 Exxon Valdez spill released 11 million gallons of oil, costing $2.1 billion to clean up, proving that environmental damage in these zones is devastating.
• Human infrastructure must be carefully managed. If the heat from heated buildings or pipelines thaws the ground beneath them, it causes thermokarst (ground subsidence) which destroys the structures.

Evaluation: Protection vs. Exploitation

When evaluating the value of wilderness areas and the need for protection (a common 9-mark structure), you must weigh intrinsic and environmental value against economic benefits:

• Arguments for Exploitation (Economic Value): Regions like Alaska offer vast resources. Resource extraction provides vital jobs, taxes (funding 90% of Alaska's state taxes), and national energy security.
• Arguments for Protection (Intrinsic & Environmental Value): The intrinsic value of untouched wilderness and its critical scientific importance (e.g., climate records in ice cores) cannot be priced. The extreme fragility of the ecosystem means damage from oil spills or vehicle tracks can take over 50 years to recover.
• Balanced Judgement: While the economic benefits of exploitation are substantial on a local or national scale, the global environmental costs (such as accelerating climate change by releasing methane from permafrost or losing the albedo effect) are far too high. Therefore, strict protection of wilderness areas is absolutely necessary, and any development must rely on rigorous sustainable management.

Technological Strategies: The Trans-Alaskan Pipeline

How do you transport oil at 65°C across 800 miles of frozen ground without melting it? The Trans-Alaskan Pipeline System (TAPS) uses cutting-edge engineering to balance economic development with conservation.

• Preventing Thaw: 420 miles of the pipeline are elevated on insulated stilts (up to 11m deep). It uses 124,000 thermosyphons (heat pipes) to extract ground heat and vent it into the air.
• Earthquake Resilience: It is built in a zig-zag pattern on Teflon-coated slider shoes to withstand earthquakes up to 8.5 on the Richter Scale without rupturing.
• Spill Prevention: TAPS features shut-off valves that completely stop oil flow in 4 minutes if a leak is detected.
• In Alaska, even homes use specific infrastructure adaptations; buildings are built on 1–2 metre-thick gravel pads to prevent heat transfer to the permafrost.

The Role of Government and International Agreements

Because cold environments span multiple countries, or exist as a global commons like Antarctica, their protection relies heavily on legislation.

• National Governments: The USA's 1964 Wilderness Act designated large parts of Alaska as wilderness, strictly banning road building and permanent structures. Furthermore, the National Environmental Policy Act (NEPA) requires Environmental Impact Assessments before any development occurs on federal land.
• International Agreements: The Antarctic Treaty (1959) signed by 53 nations designates Antarctica purely for "peace and science." Crucially, the Madrid Protocol (1991) banned all commercial mining for at least 50 years.

Assessing the Effectiveness of Strategies

• Pros: Treaties have successfully preserved biodiversity and prevented mining/war for over 60 years. Technological strategies like TAPS have allowed economic growth (funding the $44 billion Alaska Permanent Fund) while minimising spills.
• Cons: Treaties are difficult to enforce globally as there is no single governing body. Tourism remains a massive threat, with 50,000 tourists visiting Antarctica annually. These visitors often crowd fragile honeypot sites, placing intense pressure on local wildlife despite voluntary regulations capping landing limits to 100 people.
