This battle with Mr. Covey was the turning-point in my career as a slave. It rekindled the few expiring embers of freedom, and revived within me a sense of my own manhood. It recalled the departed self-confidence, and inspired me again with a determination to be free. The gratification afforded by the triumph was a full compensation for whatever else might follow, even death itself. He only can understand the deep satisfaction which I experienced, who has himself repelled by force the bloody arm of slavery. I felt as I never felt before. It was a glorious resurrection, from the tomb of slavery, to the heaven of freedom. My long-crushed spirit rose, cowardice departed, bold defiance took its place; and
I now resolved that, however long I might remain a slave in form, the day had passed forever when I could be a slave in fact. I did not hesitate to let it be known of me, that the white man who expected to succeed in whipping, must also succeed in killing me. From this time I was never again what might be called fairly whipped, though I remained a slave four years afterwards. I had several fights, but was never whipped. It was for a long time a matter of surprise to me why Mr. Covey did not immediately have me taken by the constable to the whipping-post, and there regularly whipped for the crime of raising my hand against a white man in defence of myself. And the only explanation I can now think of does not entirely satisfy me; but such as it is, I will give it. Mr. Covey enjoyed the most unbounded reputation for being a first-rate overseer and negro-breaker. It was of considerable importance to him. That reputation was at stake; and had he sent me--a boy about sixteen years old--to the public whipping-post, his reputation would have been lost; so, to save his reputation, he suffered me to go unpunished.

What conclusion can be drawn from this information? Exercise is a healthy addition to treatment for depression. Unconscious drives influence neurotransmitter levels. If an athlete feels depressed, he isn't practicing enough. Physically fit people are not at risk for depression. People can treat depression themselves and never need professional help.

Lake Erie is one of the Great Lakes of the United States. It is also the shallowest and warmest of the five lakes. The drainage basin that

surrounds Lake Erle contains urban areas, as well as agricultural and industrial areas. Because of the amount of nutrients, primarily

phosphates, being transported into Lake Erie from surrounding areas, Lake Erle experienced cultural eutrophication. The surface of the lake developed large blooms of algae, which blocked out the sunlight to the depths of the lake and caused the lake to become anoxic.

In 1972, the Great Lakes Water Quality Agreement was signed between the United States and Canada to reduce phosphate pollution. This was

the beginning of the recovery of Lake Erie. Phosphate-containing detergents have been eliminated from surrounding areas and native species have returned, but the lake is still subjected to pollution, including sewage, which results in beach closures, and invasive species, which drive out native species and change the biome.


1. Identify the source of pollution in Lake Erle. Was it a point source or non-point source of pollution? Explain your reasoning.


2. Describe two human activities that have impacted the health of Lake Erle.


3. Organophosphates are a common endocrine disruptor in many pesticides today and part of agricultural runoff. Describe the

effects an endocrine disruptor could have on human populations surrounding Lake Erle.


4. Explain the environmental effects the excessive use of detergents had on Lake Erle.


5. The Clean Water Act and subsequent legislation mandated that Industries stop dumping wastes directly into bodies of water by

building sewage treatment facilities to clean sewage water before it discharged into lakes and rivers. An average wastewater reclamation plant treats 55 million gallons a day. Calculate the amount of pollution-free water it could release into Lake Erle in a

year.

"The ‘luxury’ of having a human rights standard is to be expected in the advanced industrial democracies of the world because these countries are currently experiencing economic stability, flourishing agriculture, and reasonably stable populations. But in the developing world, the situation is more often reversed. Poverty in India, hunger in the Sahel [sub-Saharan West Africa], population pressures in China, or war and terrorism in Somalia all speak of continuing difficulties in trying to secure basic human rights for all people around the world. The so-called North-South dichotomy is a real one—part economic, part ideological, part ecological. In 1992, the [United Nations] Human Development report noted that ‘developing countries enter the global market as unequal partners and leave with unequal rewards. Furthermore, by 1990, the richest 20% of countries had national incomes 60 times greater than those of the poorest 20% of countries. ’ And, on the level of personal income the richest 20% of the world’s people get at least 150 times more than the poorest 20%. It is important to acknowledge these issues while at the same time attempting to move the international system toward a greater global human rights standard. "
