Gullivan slumped against the cold stone wall, letting out a heavy sigh. His mind was numb from staring at the same cell door for days on end, and he was beginning to think his journey had really come to an end. Gullivan’s fingers tapped incessantly, itching to grab onto a solid book. He longed to feel the rough texture of crinkled papers, run his hands across the weathered edges of well-loved covers. He had long missed the simple comforts of his desk and home library, and perhaps even the mice…

The power of knowledge is something every human should attain, but it does not always come at an ease. In Bich Minh Nguyen’s, “ The Good Immigrant Student,” she writes about the hardships and racism she endures while trying to receive a good education. Frederick Douglas, a former slave and author of, “ Learning to read and Write”, describes his determination to be literate, while at the same time explains the obstacles he had to overcome.

acidification as well. The acidification has lowered the pH levels in the oceans by .11 which has caused the ocean to be thirty percent more acidic than it was in 1751. The acidification does not affect just the coral reefs, it also affects snails, urchins, and clams because they use the calcium carbonate to make their shells. If the world continues on the path it is going on today, the pH levels will lower by 7.8 by the year 2100 which may seem far away, but it is closer than you might think.…

“Move faster, you black gip!”(pg16). While both works show mistreatment, Gregors mistreatment was because of his actual appearance of literally being a bug; Douglass lets the readers know that his mistreatment was because of his race. Fredrick Douglass is a human who was considered by law to be 3/5th of a human because he was a black man. In the beginning of the narrative we are introduced with a background of Douglass and all other slaves around him. Douglass describes the inhumane lives of…

to another key element of the “American Dream”, which is being able to provide for one’s children so that they may one day have their own dream. Rip did not teach his children anything they could benefit from when they got older, “His son Rip, an urchin begotten in his own likeness, promised to inherit the habits, with the old clothes of his father” (Irving 473). It was important for parents to focus on their children’s well-being. Not only for their children’s sake, but for the sake of the…

Ladies and gentlemen, welcome to the Henry Dorely Zoo Aquarium. This aquarium, located in Omaha, Nebraska, may be just about as far away from the ocean as it gets, but thanks to taxes and donations, everyone in this land-locked region can get a look at coasts around the world. And because this particular aquarium is the largest aquarium found in a zoo, there is a lot to see. Featured here are eleven exhibits, including the Open Oceans exhibit, and a Cold Pacific Oceans exhibit, as well as the…

Racism did not exist due to African ethnicities simply being born into a race that was naturally inferior to whites. This white supremacy was an image created by slave owners, yet accepted throughout most of America. This prejudice image was painted by the assumptions that Blacks were unintelligent, incapable, weak, and lacked human qualities such as the ability to love. However, this is far from the truth; this was not a naturally occurring concept. Instead, this image was molded so that the…

When looking at all of the environmental disasters of the United States, the BP Oil Spill and Dust Bowl are by far two of the most devastating disasters to the surrounding environment and ecosystem. Although both natural disasters have different characteristics and environmental effects, each disaster greatly impacted the surrounding ecosystems from before and after the disasters. Although the Gulf of Mexico before the BP oil spill was still known for its suffering under the effects of coastal…

read because the master believed that slaves would overpower them if they were educated. Yet, that did not stop Douglass he began to trick the White kids in the streets to teach him how to read. “This bread I used to bestow upon the hungry little urchins, who, in return, would give me that more valuable bread of knowledge. Douglass 272”. Reading was more than just an enjoyment for Douglass, the knowledge it would bring would help him free himself and others from slavery. On the other hand,…
