Use this text: Chapter 20 Cunningham, W.P., & Cunningham M.A. (2020) Environmental Science: a global concern (15th ed.)New York, NY: McGraw Hill Education. ISBN-1260486273 For your discussion I want you to think about sustainability on both the large (societal) scale as well as the small (individual) scale.  Please consider and respond to the following prompts in your discussion: Should we be changing our mindset or our materials? (i.e. think about plastic, should we be using new materials to make things like bioplastics or eliminating the use of plastics and using metal/glass instead?...or both?) What do you do currently that is sustainable (think transportation, purchasing, waste, food, etc.)? What improvements can you make? On a national level, what should our priorities be? Should we be enacting policies to promote sustainability or should we offer economic incentives and let the free market do its thing? Any other thoughts or comments on sustainability or what we need to be prioritizing to improve our environment?
