Global Environmental Change TESC I was wondering if anybody took this course before! It's a 6 upper level credit Any info will be greatly appreciated. If you know of any other 4 or 4+ upper level credits course/exam that will fulfill the natural science or Math excelsior college requirement please let me know. P.S. I only looking at upper level Description Basic fundamentals of Global Environmental Science and the ecological principles necessary to understand the factors required to maintain ecological stability and preserve worldwide resources. There are six themes considered. They are as follows: the biosphere, population growth, energy, resources, biodiversity and worldwide resources. Thank you much, Pilot
