Document Summary
Keep it with you so you can reference as it will understand where you are regarding a variety of issues. At least for the next couple of lectures bring it with you. Bio-fuels are what the lab is about this week. This is an extremely important area so i won"t discuss it today. The argument is that they will replace or significantly substitute for fossil fuels. You will see where we have been as a benchmark and potentially where we are going. About 10% of the earth"s land surface is permanently covered in ice.
