Critically think about what you’ve learned in class this week about California’s beaches through the historical lens as it relates to access equity and inclusion. Research your assigned beaches through these lenses. Perhaps there are other interesting histories of your beaches. How do they compare and contrast with California? Write a thoughtful reflection on the material you are learning about this week and how you can relate it to your international beaches. Use examples from your readings and research. Remember to CITE YOUR SOURCES. If you include information that is not common knowledge, include a parenthetical reference and a citation at the end. Remember plagiarism is a violation of our honor policy and will result in a 0 on this assignment and be reported to the university.
Respond to one another (at least 2 engagements). Use this opportunity to critically think about what you are learning, how you can use these lenses to think about your international beaches, and start sharing that with your group. Be respectful and thoughtful in your tone, and share your insights with your team.
Your reflection should be between 300-500 words. Your responses and engagements should be at least a paragraph.

What is an example of an environmental justice concern in North Texas or in your area?
Do you think the concerns of environmental justice advocates are justified?
What could be done to ensure that poor communities do not suffer more hazards than wealthy ones?
Please respond to the questions and to one other student. Make sure you write at least 4 good complete sentences for your response to the questions and 2 good complete sentences when you respond to someone else in the class for full credit.
