TEXT B The United States has a major racial problem on its hands. True, Britain is facing a similar problem, but for the time, being it is in America that it is graver. The only way to solve it is through education. Negroes should know about the contributions that black individuals and groups have made towards building America. This is of vital importance for their self-respect, and it is perhaps even more important for white people to know. For if you believe that a man has no history worth mentioning, it is easy to assume that he has no value as a man. Many people believe that, since the Negro’s achievements do not appear in the history books, he did not have any. Most people are taken aback when they learn that Negroes sailed with Columbus, marched with the Spanish conquerors of South America and fought side by side with white Americans in all their wars. People are astonished when you tell them about Phillis Wheatley, who learned English as a slave in Boston and wrote first-class poetry. They have never heard of Benjamin Banneker, a mathematician and a surveyor, who helped to plan the city of Washington. There has been a tendency all along to treat the black man as if he were invisible, little has been written about the 5,000 American Negroes who fought in the Revolution against the British, but they were in every important baffle. In the Anglo-American war of 1812, at least one out of every six men in the U. S. Navy was a Negro. In the Civil war, more than 200,000 black troops fought in the Union forces. How, then, did the image of the Negro as a valiant fighting man disappear To justify the hideous institution of slavery, slaveholders had to create the myth of the docile, slow- witted Negro, incapable of self-improvement, and even contented with his lot. Nothing could be further from the truth. The slave fought for his freedom at every chance he got, and there were numerous uprisings. Yet the myth of docility persisted. There are several other areas where the truth has been twisted or concealed. Most people have heard of the Negro. Carver, who invented scores of new uses for the lowly peanut. But whoever heard of Norbert Rillieux, who in 1846 invented a vacuum pan that revolutionized the sugar-refining industry Or of Elijah McCoy, who in 1872 invented the drip cup that feeds oil to the moving parts of heavy machinery How many people know that Negroes are credited with inventing such different items as ice creams, potato chips, the gas mask and the first traffic light Not many. As for the winning the West, the black cowboy and the black frontiersman have been almost ignored, though film producers are becoming more aware of their importance. Yet in the typical trail crew of eight men that drove cattle from Texas to Kansas, at least two would have been Negroes. The black troops of the Ninth and Tenth Cavalry formed one-fifth of all the mounted troops assigned to protect the frontier after the Civil War. What difference does it make You may ask. A lot. The cowboy is the American folk-hero. Youngsters identify with him instantly. The average cowboy film is really a kind of morality play, with good guys and bad guys and right finally triumphing over wrong. You should see the amazement and happiness on black youngsters’ faces when they learn that their ancestors really had a part in all that. How were the Negroes treated in the history books

TEXT A The destruction of our natural resources and contamination of our food supply continue to occur, largely because of the extreme difficulty in affixing legal responsibility on those who continue to treat our environment with reckless abandon. Attempts to prevent pollution legislation, economic incentives and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays—not only in accepting responsibility, but more importantly, in doing something about it. It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industry’s and our recognition that protecting mankind’s great treasure is the single most important responsibility If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now. We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge. We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer afford to be tunnel-versioned in our approach. We must visualize issues’ from every perspective make the objective decisions. We must express our views clearly to prevent media distortion and public confusion. I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages. Which of the following, according to the author, should play the leading role in the solution of environmental problems
