Right outside of UCSD, the intersection of La Jolla Village Drive and Villa La Jolla Drive is one busy intersection. I took this photo at 9 P.M. on a Sunday night and it is full of cars going by. Can you imagine how many cars there are on a regular day at regular hours? How much carbon dioxide and other toxic chemical get released into the atmosphere? How much is that do we breathe in?
