This is a great class to take if you need a science GE and are not a science major. I took this class at the same time as Intro to Oceanography, and in comparison with the Ocean class this class was a lot more reasonable in amount of reading and material we were expected to cover in the class. I would definately recommend this class over the Ocean class because Lew has painstakingly thorough notes online for every slide on his lecture notes, and he has open note open neighbor quizzes and it's just a reasonable workload which makes it fun as well as entertaining. However you will have to study to do well on the midterm and final it is not just an easy A, and Lew is very anal about spelling, grammar, and exact wording.
