What is Environmental Studies? What do you think? • What is the current “state” of the planet? • What is our role on earth? • What is our “long-term” plan for sustainability? • Do we have an obligation to other living things? • Do we have an obligation to future generations? • Where do you stand?

ES 1- HOMEWORK ASSIGNMENT # 2 ROEDER- WINTER 2020- 10 TOTAL POINTS FOR EACH QUESTION= 40 POINTS TOTAL As humans, we consume products every day. Those products are made from resources extracted from the earth. As global populations grow, the amount of resources available to support life on earth are under siege. As you learned in week 1, some of those resources we use can’t replenish themselves faster than we will use them. The manufacturing, transportation, packaging and disposal of the things we buy create a number of environmental issues. We deplete precious earth resources and pollute the planet in many ways. Please answer the following questions using the resources on the class website. I am expecting a STRONG PARAGRAPH for each answer you provide. 1) From the Lecture, “Ecosystem Services and the Three Types of Resources”, what is the difference between non renewable resources and renewable resources? Why is it important we understand the difference? 2) From the Lecture, “Ecosystem Services and the Three Types of Resources, Explain the Sustainability Triangle, or Triple Bottom Line of Sustainability. Explain the importance of the inter-relationship between People, Planet and Profit 3) After watching the video and looking at the lecture on , “Earth Overshoot Day”, EXPLAIN IN A STRONG PARAGRAPH three ways society can start to push Earth Overshoot Day back toward December 31 4) In the video, “Earth Provides Resources”, what are some of the economic and environmental justice issues associated with resources being distributed unevenly across the globe? What issues does that cause and to whom? ... Purchase answer to see full attachment
