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.

The Role of Educators: Protecting Australia’s Ecosystems for Future Generations

As educators, we play a crucial role in inspiring the next generation of environmental stewards. By teaching students about the importance of habitats, the human impact on ecosystems, and ways to protect the environment, we can help ensure a sustainable future for Australia’s natural landscapes and marine life.

Together, we can make a difference! 🌊🐠💙

Year 6 Science Incursions in Brisbane

 

Open Ocean Habitat

Ocean Life Education’s Habitats Program

Ocean Life Education’s Habitats – Physical Conditions program elevates Year 6 students’ understanding of habitats by focusing on marine environments. Students will explore the specific physical conditions required for marine animals to survive and thrive. They will learn how changes to these conditions can negatively affect marine life, leading to poor health or even death. The program encourages discussions on strategies to prevent these harmful impacts in the future.

During our Habitats incursions, students will delve into a diverse range of physical conditions, including:

  • Temperature
  • Salinity
  • Light
  • Nutrients
  • Current flow
  • Waves
  • Turbidity
  • Depth
Coral Habitat

The Great Barrier Reef

Habitats Case Study: The Great Barrier Reef, Queensland

Our focus will be on Queensland’s coral reef habitat, particularly the Great Barrier Reef, the world’s largest fringing reef, located right at our doorstep. As one of the seven natural wonders of the world, it is essential to understand the physical conditions necessary for its survival so we can work to preserve it for the future.

What is Coral?

coral polyps

coral polyps

Though corals resemble plants on the ocean floor, they are actually marine animals related to jellyfish and sea anemones. Corals belong to the Cnidaria group, known for their stinging tentacles.

These invertebrates are colonial organisms, meaning many individuals live and grow connected in colonies. The Great Barrier Reef hosts around six hundred coral species which are made up of polyps, clear tube-like structures with stinging tentacles used for catching prey and defence.

Coral Reef Habitat – Necessities to Thrive

Temperature: Corals thrive in warm tropical waters, ideally between 23–29°C.

Salinity: They prefer salty conditions with salinity levels between 32–42 ppt.

Light: Sunlight is crucial for coral survival, as symbiotic algae within them need to photosynthesize to produce food.

Nutrients: Low nutrient levels are important to prevent smothering; calcium is essential for building coral skeletons.

Current Flow: Currents bring food, calcium, and disperse sediment, aiding in photosynthesis and coral spawn distribution.

Waves: Waves provide oxygen, food, and prevent sediment buildup on corals.

Turbidity: Low turbidity ensures sunlight penetration, crucial for coral survival.

Depth: Corals thrive in shallow waters, up to 70 meters, but prefer depths between the surface and 30 meters for optimal sunlight.

Human Impact

Coral Bleaching

Students will explore how human activities have altered the reef’s physical habitat and its effects on marine life. They will also discuss strategies to minimize negative impacts on the reef now and in the future.

Coral Bleaching

Climate change has raised water temperatures, especially in the northern Great Barrier Reef, surpassing 29°C and causing coral bleaching. Discussions will cover human actions like carbon pollution from cars and factories that accelerate climate change. Students will learn about coral bleaching, its causes, and potential prevention measures.

Land Clearing

The removal of trees and vegetation near coastal and river areas increases soil erosion, leading to sediment washing into oceans. This sediment smothers and kills coral. Students will investigate the effects of land clearing on marine environments.

Extension to Human Impact on the Ocean

Other human activities like plastic pollution and the use of shark nets and baited drum lines for shark control will be discussed. Students will learn about plastic’s harmful effects on marine life, particularly sea turtles.

The use of shark nets and drum lines since 1962, which results in unnecessary harm to marine animals, will be debated. The discussion will focus on modern, more effective technologies for protecting humans and marine life at beaches.

Engage Kids with Sharks

online sharks course

Most children (and adults!) are naturally fascinated by sharks, either through sheer awe and wonder or by misguided fear. So, it’s no surprise that we can engage kids with sharks to learn a whole range of curriculum topics, without them even realising!

Ocean Life Education has developed a range of FREE online shark teaching resources and an online shark course to provide kids, schools and teachers with engaging ways to learn about sharks.

Why Are Kids Fascinated by Sharks?

shark anatomy and adaptation

shark anatomy – amazing sharks online course

Unfortunately, kid’s interest in sharks is often fuelled by exaggerated media stories and scary films, but it’s sharks’ appearance, immense power and ability to hunt that really grab their attention.

Incredibly, sharks have been around for at least 450 million years (since before the dinosaurs). A major reason why sharks have outlasted so many other animals, and a key reason why we are so fascinated by sharks, is their incredible anatomy, which is adapted to hunt and to survive.

 

 

Teaching Kids About Sharks Helps Protect Sharks and The Ocean

sharks & natural selection

sharks & natural selection

As APEX predators, sharks sit at the top of the food chain and help control the numbers of animals below them in the food web, thus maintaining the balance of life in their marine habitat. By controlling populations of large and mid-sized predators, sharks allow smaller fish to thrive, ensuring healthy ecosystems with a diverse range of species and competitors. Take sharks out of the food chain and the whole structure could collapse.

As we depend on healthy oceans for around 70% of the air that we breath, as well as for a host of other things such as food to eat, it is in our interest to minimise human impact and protect animals that protect our ocean.

 

Curriculum Themes and Sharks

Through the fascinating topic of sharks, kids can learn a host of curriculum themes such as adaptation, habitats, human impact, food webs, natural selection and classification. Studying the curriculum, while being thoroughly engrossed in the subject matter, makes the process of learning all the more enjoyable and inspiring.

Learning Enrichment and Sharks

Often children who need extra support within learning enrichment respond really well to curriculum-based learning which is based around their own topic of interest. That’s where teaching ‘Sharks’ can be a really useful tool to stimulate interest and hook children in.

 

Sharks Course for Kids & Shark Teaching Resources 

 

Ocean Life Education has created a host of engaging FREE shark teaching resources and activities: videos, sharks factAmazing sharks sheets & infographics, shark worksheets, shark activities, shark quizzes and an online shark course for kids (and adults!), with the aim of promoting understanding of sharks.
