🔍 What Role Do Sharks Play in the Ecosystem? Why we Depend on the Ocean

  1. Balance Marine Populations
    Sharks regulate the populations of prey species like rays and smaller fish, preventing them from overgrazing critical habitats like seagrass and coral reefs.
  2. Support Ocean Biodiversity
    By preying on weak or sick individuals, sharks help keep marine species healthy, promoting genetic strength and ecological balance.
  3. Drive Evolution
    Sharks influence the behaviour and evolution of other marine animals. Their presence encourages adaptive traits and survival strategies in prey species. Watch our Shark Adaptation Mini Video here and check out our Adaptation themed programs.
  4. Indicate Ocean Health
    A thriving shark population is a key sign of a healthy ocean. Sharp declines in shark numbers often signal wider problems in the marine food web, with long-term consequences for both wildlife and human communities.

The Human Impact: How Our Actions Shape Marine Habitats and Ecosystems

 

Each day, our actions impact on the environment, shaping marine habitats and ecosystems that countless species depend on for their survival. From the bleaching of the Great Barrier Reef to melting polar ice caps, day by day human impact is driving significant changes in our natural world. In understanding such impacts, we can teach students how to protect the fragile ecosystems that sustain life on earth.

Australia’s Great Barrier Reef: A Unique Marine Habitat at Risk

Located along Australia’s northeast coast and spanning over 2,300 kilometres, The Great Barrier Reef, is one of the world’s most complex and diverse ecosystems.  It is home to over 1,500 species of fish, 400 types of coral, and a diverse range of other marine creatures like sea turtles and dugongs. This beautiful and vibrant reef is an essential marine habitat that supports abundant marine life, protects Australia’s eastern coastlines from erosion, and contributes to global climate regulation.

However, this remarkable ecosystem is under threat due to human impact. Climate change, pollution, and overfishing are causing severe disruptions, including coral bleaching and the destruction of critical habitats. If we don’t act soon, the survival of the Great Barrier Reef’s diverse species—and the livelihoods of Australian communities that rely on it—will be at risk.

The Effect of Human Impact on Australian Marine Ecosystems – Coral Bleaching

Coral bleaching occurs due to rising ocean temperatures. Human Impact contributes to this climate change, as pollutants from vehicles and factories create an insulative layer in our atmosphere. Persistently warmer water temperatures cause corals to expel the algae that provide them with food and vibrant colours. Without these algae, corals become vulnerable and they eventually die, leaving behind a bleached, lifeless coral reef. Temperature rise isn’t the only problem—ocean acidification, driven by increased carbon dioxide levels, also weakens coral skeletons, making them more susceptible to damage.

Marine ecosystems are disrupted by the loss of coral reefs and this in turn harms local economies, including tourism and fishing industries that depend on these habitats for healthy fish stocks.

Polar Bears and Habitat Loss: The Impact of Melting Ice

The melting of polar ice caps is one of the most visible effects of human impact. These ice caps provide critical habitat for polar bears, who rely on the sea ice for resting, hunting, and breeding. As ocean temperatures rise, polar bear’s ice habitat is rapidly disappearing, causing them to need to travel and swim longer distances to find food. This can lead to exhaustion and starvation.

This reduction in the volume of ice also brings polar bears into closer contact with humans as they search for food in populated areas inland, increasing the potential for conflict. If global temperatures continue to rise, polar bears and the Arctic ecosystem could be in jeopardy .

2025 has been named the UN International Year of Glacier’s Preservation. This is to highlight the importance of glaciers and the fact that they are disappearing at an alarming rate,

How Schools Can Help Protect Habitats and Ecosystems

At Ocean Life Education, we partner with Australian schools to teach students about the importance of protecting habitats and ecosystems. Human impact—such as plastic pollution, overfishing, and habitat destruction—can harm these ecosystems, but small changes in our daily lives can make a difference. Teaching students how to reduce waste, conserve energy, and support sustainable practices helps protect the ecosystems they rely on.
