Global warming

Austin is a very environment concious city, so ive seen alot of efforts to cut down on global warming in my community.  Almost everyone I know recycles, and I see alot of hybrids and small cars driving around, even some smart cars.  The city is often planting grass and trees to combat carbon dioxide emissions.  Over the past two weeks Ive been pretty busy with school work, especially with math.  I just moved up from regular to pre-AP math and its alot harder.
