The first question is technical and dives into some chemistry, so do your best to answer (and include citations!). Answer questions 1 and 2 on page 1, questions 3 and 4 on page 2. Page 1 1. Outline the chemical reactions that lead to stratospheric ozone depletion and explain why ozone depletion happens more readily at the poles compared to the mid-latitudes. 2. Describe two ways in which ozone depletion may affect climate change or vice versa. Given the complexity and uncertainties about how these two phenomena interact, do you think further control of ozone-depleting substances should be pursued and why? Page 2 3. Discuss the water problems that plague Bangladesh. How have expanding human populations in Bangladesh and adjacent countries exacerbated these issues? How might some of these issues be addressed in the future? 4. Discuss the geographic and geologic conditions that created the Ogallala Aquifer (See The High Plains (Ogallala) Aquifer System section in Montgomery, C.W. (2019). Environmental Geology, 11th textbook, pp.256 – 257). What factors have led to its depletion? Why has it been so hard to implement conservation strategies to extend its use?
