Thirdly, I worry about the private automobile. It is a dirty, noisy, wasteful, and lonely means of travel. It pollutes the air, ruins the safety and sociability of the street, and exercises upon the individual a discipline which takes away far more freedom than it gives him. It causes an enormous amount of land to be unnecessarily abstracted from nature and from plant life and to become devoid of any natural function. It explodes cities, grievously impairs the whole institution of neighbourliness, fragmentizes and destroys communities. It has already spelled the end of our cities as real cultural and social communities, and has made impossible the construction of any others in their place. Together with the airplane, it has crowded out other, more civilized and more convenient means of transport, leaving older people, infirm people, poor people and children in a worse situation than they were a hundred years ago. It continues to lend a terrible element of fragility to our civilization, placing us in a situation where our life would break down completely if anything ever interfered with the oil supply.Which of the following best describes the organization of the passage?
