HUMAN DEPENCE ON THE ENVIRONMENT PRE-LEARNING ASSIGNMENT

TEK 8.11D: Recognize human dependence on ocean systems and explain how human activities such as runoff, artificial reefs, or use of resources have modified these systems.

Title for notes: Human Dependence on Environment

Question: How do humans depend on the environment?

In this pre-learning activity, take notes directly in Word or PowerPoint, through office 365, and save the document to office 365, we will print your ecosystems notes and these notes later and you will use them for your Ecosystems and your Ocean Awareness Project. -Each section must have at least 3 relevant pictures to go along with your notes.
