Throughout the world the land has been bulldozed under to make way for these automobiles, destroying the land. Automobile pollution has cause considerable harm to the ecology. In places such as Los Angeles and Mexico City it is difficult to breath when the air is stagnant. Industry has also greatly contributed to the break down of the ECO System. With the coming of the engine, factories came upon the land like locust, arising from their sleep.
Industry eats up the land, making way for buildings and parking lots.
So that the little house on the homestead has become the skyscraper in the city. The waste of industry from the power of the engine bellows out of the smoke stacks of their buildings. They leave a trail of smoke and ash, so that the sky has been darkened and tainted with poison. The rain that once was clean now falls from clouds as acid. In this, the plant life of this earth is in eminent peril.
