Car

    "Automobiles changed the world in the 20th Century. 

      They have given people the

      freedom to live, work, and travel almost anywhere they want. The automobile 

      industry has caused the suburbs to grow, and made the development of road and

      highway systems necessary. The manufacture, sale, and repair of automobiles are

     very important to the countries that produce large amounts of manufactured goods. But along with the advantages of automobiles, there have been

      disadvantages. Automobile accidents are a leading cause of death and injury in the

      world, and the automobile has brought about air and noise pollution. Despite the

      problems automobiles have caused, they are an important part of the culture and economy of the world."
