• Fisheries Support: Providing breeding grounds and habitats for commercially important fish species.
• Tourism Revenue: Generating billions of dollars in revenue through tourism and recreation.
• Carbon Sequestration: Absorbing carbon dioxide from the atmosphere, helping to regulate the climate.

1.2. Why Is the Great Barrier Reef Under Threat?

The Great Barrier Reef faces a multitude of threats, both natural and human-induced. These include:

• Climate Change: Rising ocean temperatures cause coral bleaching, a phenomenon where corals expel the algae living in their tissues, leading to starvation and death.
• Pollution: Runoff from agriculture, industry, and urban areas carries pollutants, such as pesticides, fertilizers, and heavy metals, which harm coral and other marine life.
• Crown-of-Thorns Starfish: Outbreaks of these coral-eating starfish can decimate large areas of the reef.
• Overfishing: Unsustainable fishing practices can disrupt the food chain and damage reef habitats.
• Shipping: Ship groundings and oil spills can cause significant damage to the reef.
• Tourism: While tourism brings economic benefits, it can also contribute to the reef’s decline through various direct and indirect impacts.

2. How Tourism Directly Harms the Great Barrier Reef

Tourism’s impact on the Great Barrier Reef can be direct and immediate, often resulting from unsustainable practices and a lack of awareness among visitors.

2.1. Physical Damage to Coral

One of the most visible impacts of tourism is the physical damage to coral caused by:

• Touching and Breaking: Unintentional contact from snorkelers, divers, and even boat anchors can break or damage fragile coral structures.
• Boat Anchors: Anchors dropped carelessly can crush coral and disrupt the seabed.
• Walking on Reefs: During low tide, people may walk on exposed reefs, causing significant damage to delicate coral.

According to the Great Barrier Reef Marine Park Authority (GBRMPA), even seemingly minor physical damage can have long-lasting consequences. Coral grows slowly, and it can take decades for a damaged reef to recover, if it recovers at all. Repeated damage can weaken the reef’s overall structure, making it more vulnerable to other threats.

2.2. Pollution from Tourism Activities

Tourism-related activities can generate various types of pollution that harm the Great Barrier Reef:

• Sewage and Wastewater: Untreated or poorly treated sewage from boats and coastal developments can introduce harmful bacteria, viruses, and nutrients into the water, leading to algal blooms and coral disease.
• Fuel and Oil Spills: Boats and other watercraft can leak fuel and oil, which are toxic to marine life and can smother coral.
• Litter and Plastic Waste: Plastic waste, including bottles, bags, and fishing gear, can entangle marine animals, pollute the water, and break down into microplastics, which can be ingested by marine organisms.
• Chemicals from Sunscreen: Many sunscreens contain chemicals like oxybenzone and octinoxate, which have been shown to damage coral DNA, disrupt coral reproduction, and cause coral bleaching.

A study published in the journal Archives of Environmental Contamination and Toxicology found that even low concentrations of oxybenzone can have significant negative impacts on coral health.

2.3. Disturbance of Marine Life

Tourism activities can disrupt the natural behavior of marine life in several ways:

• Feeding Wildlife: Feeding fish or other marine animals can alter their natural foraging behavior, making them dependent on humans and disrupting the food chain.
• Noise Pollution: Boat traffic and other noise can disturb marine mammals, such as whales and dolphins, affecting their communication and navigation.
• Habitat Disruption: Construction of resorts and other tourism infrastructure can destroy or degrade critical habitats for marine life.

According to the Australian Marine Conservation Society, maintaining a respectful distance from marine life and avoiding any activities that could disrupt their natural behavior is crucial for responsible tourism.

3. How Tourism Indirectly Harms the Great Barrier Reef

Beyond the direct impacts, tourism also contributes to the degradation of the Great Barrier Reef through indirect mechanisms.

3.1. Coastal Development and Infrastructure

The demand for tourism infrastructure, such as hotels, resorts, marinas, and airports, often leads to:
