If an alien were to land on earth, the first thing he would notice about the "green planet"is the amount of cars there are on the streets. He would see that they come in all shapes and sizes, colors and are of many different brands. He would attempts to count the cars, but would get lost quickly because no brain can comprehend a number so large. In 1900 there were only 4,192 passenger cars built in the US (the only country to be manufacturing cars). There were no buses or trucks. By 1985 there were 109 million cars in existence. Today, with dozens of countries participating in the creation of automobiles, that number is six times larger.
It is estimated that there are approximately 600 million motor vehicles being driven on the streets of earth, the alien would be dumbfounded with this number. The biggest manufacturers are Japan, producing 8,056,000 cars in 1998, the US, with 5,554,000, and Germany with 5,348,000. With passing time, these numbers experience a rapid growth. For example, in 1960 Japan produced 185,000 cars, but by the end of the 1990s it was producing nearly 10 million a year. It is believed that at this growth rate, the number of cars on earth will double within the next 30 years. In this time scientists predict that traffic congestion will become 10 times worse than it is today. If in 2001 it is difficult to cross a major street without having to wait five minutes for the traffic to stop, how long will one have to wait in 2050?
Today the alien will notice that with such a large number of cars and people on earth, there are approximately ten people per car. But what will happen when he returns for a second trip in a hundred years? Will there be as many cars as people, or maybe by that time we'll have discovered a new method of transportation that is much more efficient and eco-friendly than the car? Only time can tell.
