Task: Analyzing the Impact of Human Activities on Ecosystems

Objective: Students will analyze the impact of human activities on ecosystems in Texas, as outlined in Texas TEK 7.8.

Instructions: 1. Research and select one specific human activity that has had a significant impact on an ecosystem in Texas. This could include activities such as deforestation, urbanization, agriculture, mining, or pollution. 2. Create a presentation or report that includes the following components: a. Introduction: Provide a brief overview of the chosen human activity and its relevance in Texas. b. Description of the Ecosystem: Describe the ecosystem that has been affected by the chosen human activity. Include information about its location, biodiversity, and ecological importance. c. Impact Analysis: Analyze the specific impact of the chosen human activity on the ecosystem. Consider both short-term and long-term effects, such as habitat destruction, loss of biodiversity, water pollution, soil degradation, or climate change. d. Case Studies: Include at least two case studies or examples that illustrate the impact of the chosen human activity on different ecosystems in Texas. These case studies should provide specific details and evidence to support your analysis. e. Mitigation Strategies: Propose at least two strategies that could help mitigate the negative impact of the chosen human activity on the ecosystem. Explain how these strategies could be implemented and their potential effectiveness. f. Conclusion: Summarize the main findings of your analysis and discuss the importance of considering the impact of human activities on ecosystems in Texas. 3. Present your findings to the class, either through a formal presentation or by sharing your report. Be prepared to answer questions and engage in a discussion about the topic.

Note: Encourage students to use reliable sources, such as scientific journals, government reports, or reputable websites, to gather information for their analysis. Remind them to properly cite their sources and avoid plagiarism.
