Ecosystems encompass the biological community in a certain environment, including the plants, animals, and microorganisms that reside there, together with the physical aspects such as weather, soil composition, and atmosphere. Changes in ecosystems occur naturally over time due to processes such as weathering, erosion, and succession. However, human activity has significantly escalated the pace of these changes, often with harmful consequences.
Understanding the mechanisms behind these ecosystem changes is key to much of contemporary biology. It not only aids us in predicting and preparing for future changes but also equips us with the knowledge to take necessary action to mitigate harmful alterations, thus preserving biodiversity and maintaining the balance of nature.
Human-induced activities such as deforestation, pollution, overfishing, and climate change have significantly altered the density and diversity of various ecosystems. These actions have led to habitat loss and a rise in endangered species, hence disrupting the normal functioning of the ecosystem. Understanding these changes is not merely a theoretical exercise but rather a practical necessity in light of the ongoing environmental crisis.
In today's interconnected world, even the most isolated ecosystems do not exist in a vacuum. Changes in one area can have a domino effect, impacting other ecosystems both near and far. This ripple effect underscores the inherent fragility of our planet's ecosystems, making it crucial for us to understand and respect the delicate balance that exists within and between different ecosystems.
The aim of this project is to elucidate the concept of Ecosystem Changes, the causes and effects, and the ability of ecosystems to resist or adapt to these changes. You will learn how to critically analyze a situation, apply theoretical knowledge to real-world scenarios, collaborate with your teammates, and develop possible solutions to mitigate these changes.

Activity Title: Ecosystem Alteration – A Case Study
The aim of this activity is to help students gain a comprehensive understanding of how, why, and to what extent ecosystem changes occur due to both natural and human-induced events.
In this activity, the students in groups are required to select a real-world ecosystem that has undergone significant changes due to certain reasons. They will then carry out a thorough research project to understand the causes, effects, and potential solutions to minimize or reverse the negative effects of these ecosystem alterations.
- Internet access for research
- Notebooks for recording findings
- Presentation tools (PowerPoint, Google slides, etc.)
Formulation of Groups: Form groups of 3 to 5 students. Each group will work collaboratively throughout this project.
Selection of Ecosystem: Each group will choose a specific ecosystem that has experienced significant changes. It could be a local forest that is affected by logging, a lake that has been polluted, etc.
Research Phase: Each group will carry out detailed research on their chosen ecosystem, focusing on factors like:
- Description of the original state of the ecosystem
- Causes for the changes in ecosystem (both natural and human-induced)
- Impact of these changes on the local flora and fauna
- How these changes trickle down in the food chain and affect other ecosystems
Synthesis of Information: Analyze the information gathered, drawing connections between the cause, effect, and the ripple impact of these changes.
Formulating Solutions: Each group must brainstorm and propose potential solutions or prevention strategies to curb further negative impacts on the chosen ecosystem.
Presentation: Create a presentation to disseminate your findings. Your presentation should be engaging, informative, and should effectively communicate your learning and proposals for change.
Report Writing: After the presentation, each group will compile their findings, analysis, and proposed solutions into an organized and detailed report.
Your report should include four main sections:
Introduction: Here, you should present the context of the study, detailing the selected ecosystem, its significance, the changes it has faced, and the objectives of your project.
Development: This section should cover the detailed description of the ecosystem changes, causes, effects, and how these changes have influenced the ecosystem and other interconnected ecosystems. A description of your research methodology, findings, and discussions should also be included.
Conclusions: Summarize your main findings, learning, and the outcome of your brainstorming session. List the proposed solutions and preventive strategies.
Used Bibliography: Cite the resources (books, articles, videos, etc.) that you have consulted during your research.
The entire project duration will be one week. Throughout this week, work collaboratively, dividing tasks, and facilitating effective communication and teamwork.
At the end of the week, each group will present their findings, supplemented by a detailed report following the structure mentioned above. The group effort in research, presentation, and problem-solving solutions will assess your understanding of changes in ecosystems, and your competencies in collaboration, critical thinking, and communication.
