Marine Ecosystems and Human Impact on Oceans

Introduction

Have you ever wondered why coral reefs are called the “rainforests of the sea”? Our oceans provide food, oxygen, and livelihood for millions of people. However, pollution, climate change, and overfishing threaten marine ecosystems.

In this WebQuest, you will become Marine Conservation Advocates. Your mission is to investigate problems affecting ocean ecosystems and propose realistic solutions to help protect them.

Are you ready to save the ocean?

Task

You and your group will:

  • Research one major issue affecting marine ecosystems (e.g., plastic pollution, coral bleaching, overfishing, oil spills).

  • Explain its causes and effects.

  • Propose practical solutions.

  • Create a digital presentation (PowerPoint/Canva/Google Slides) or infographic poster presenting your findings.

  • Present your output to the class.

Your final product should show understanding, creativity, and evidence-based solutions.
