text: The private owning of vehicles is convienient, but is still a hazard to the genearal health of our population. It poisons the air, and gives people an excuse to not walk or ride their bycyles as much, which can diminish their physical health. If we start to use privately owned vehicles less, however, it will promote the general welfare of our people. It is possible to cut the use of these vehicles short and preserve, even raise, our standards of living.    The face on Mars is a very interesting thing. It looks like a human head but there is now way it could be because it is two miles long. Some people say that is was made by aliens. NASA says that it is just a rock formation that happend naturaly. There are many arguments for both sides. I'm going to tell you the arguments from the side that says it is just a natural rock formation. This face on Mars is a natural rock formation because, if it were made by aliens than when they got close to it they would have saw things that would be unatural. Another reason is it looks like buttes and mesas that we have here in the United States. Lastly we have been studying this for twenty five years and never before has an alien came up and said, "Hi I made this".
