Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and will lead to several problems that affect the environment in which we humans live in. These problems can lead to warmer temperatures all around the world, it can endanger animals and the wildlife, and it can lead to widespread flooding from the glaciers melting. Here are a few more future effects that I will discuss in more detail about. Damage to human health, Severe stress on forests, wetlands, and other natural habitats, how fish will be affected. Global warming is a serious problem that will affect our generation when we are older.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...

... areas will get more precipitation and storms while others will get nothing and have serious droughts. The warming of a few degrees will cause glaciers to melt and sea ice to melt leading to a lot of damage. This damage would lead the levels of the oceans to rise and would cause damage to coastal cities and islands. This would cause serious problems for the different species living in the oceans and could some disease. Especially diseases caused by mosquitoes which love warm and humid climates. There are many ideas and solutions to stop global warming. It is very difficult to reverse this process once it is started. If we want to live like we are now and have been we have to stop this process. Emissions of fossil fuels by humans is a big factor of global warming. The reason being is because of the amount of carbon dioxide released from the fossil fuels. Controlling these emissions is one huge step of many steps required to slow down and stop global warming. If global warming is not controlled, all the problems that have been mentioned, along with other problems will disrupt the living patterns in which we live.
Uncle Tom’s Cabin is an anti-slavery novel written by Harriet Beecher Stowe in 1850s that “changed forever how Americans viewed slavery, the system that treated people as property”. (Harriet Beecher Stowe Center) This book “demanded that the United States deliver on the promise of freedom and equality, galvanized the abolition movement and contributed to the outbreak of the Civil War”. (Harriet Beecher Stowe Center) “The strength of Uncle Tom's Cabin is its ability to illustrate slavery's effect on families, and to help readers empathize with enslaved characters.” (Harriet Beecher Stowe Center) As Foner mentioned: “By portraying slaves as sympathetic men and women, and as Christians at the mercy of slaveholders who split up families and set bloodhounds on innocent mothers and children, Stowe’s melodrama gave the abolitionist message a powerful human appeal.” (472) With this novel, Stowe wanted to convince Christians that God doesn’t’ approve slavery, that it is evil which must be destroyed.
Uncle Toms Cabin gives a deeper understanding of the hardships of slavery in America and how these people were treated, in a country that was supposed to be of all men created equal. Though this book goes deeper than what is presented at face value, though racism is also a very large and important part of this story. Harriett Beecher Stowe reveals more in her novel than just the terrible acts of slavery, and what it was like to be stuck as a slave with no way out. In this story she gives two different perspectives in my opinion, one of tremendous sorrow, and struggle as we follow Tom throughout the story and feel and see the pain and hardships he must endure. And the other of Eliza who does a extremely courageous thing in trying to smuggle her son off the plantation in order to save her son from being sold to a coarse slave owner. Uncle Toms Cabin is a book that illustrates not only the need to end slavery and the incompatibility of slavery with the values of Christianity, but emotionalism, the importance of keeping ones faith, as well as women being viewed as equals.
Stowe is trying to prove to the reader that slavery is wrong and nothing short of evil and cruel. She does an effective job at proving her point, while delivering a superb novel at the same time. Stowe is constantly tying to prove that slavery is evil. She opens the novel, by showing two slave owners, making a business deal. Mr. Shelby is in debt to Haley, so he must sell Uncle Tom and Harry, tearing them apart from their families. Stowe shows a young slave woman, Eliza and her affection for her son Harry, when she decides to take her son and run away. This disputes the common belief of the time that slaves mothers has less affection for their youth than white women. Uncle Tom is sold again to the carefree Augustine St. Clare whos philosophy is “Why save time or money, when there's plenty of both?” Uncle Tom receives good treatment at the St. Clare’s, which proves that the novel is not one-sided, showing that their where kind slave owners. However Uncle Tom is sold again, this time up the Red River to the “devil” Simon Legree.
Global warming is a scientific, political, and controversial topic. Some believe it is catastrophic, a slow moving killer hiding in the shadows. Others do not even think twice about it as they race by in a Hummer. Global warming is the gradual increase of temperature throughout different climates. It is caused by the greenhouse gas effect in which greenhouse gases, like methane and carbon dioxide, reflect sunlight back and forth. This reflected ultraviolet light bounces between the earth and the ozone layer and becomes trapped, resulting in a gradual rise of temperature. Over time, the slow rise of temperature causes new climates throughout the globe. The article “What Megablazes Tell Us About the Fiery Future of Climate Change” by Tim Dickinson
In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,
Flocken endorses that “...hunters are not like natural predators.They target the largest specimens; with the biggest tusks, manes, antlers, or horns.” In Defense of Animals International (IDA) argues that hunters concentrate on“game” populations and ignore “non-game” species that may lead to overpopulation and unequal ecosystems. Therefore, it affects their ecosystem, and the animals’ families. Overall, the evidence proves trophy hunting hurts the environment, specifically conservation. Therefore, the hunters’ idea that trophy hunting actually helps conservation by killing some predators to maintain balance, is merely
Years ago, killing animals for food was part of the average man’s everyday life. While, now a days, hunting is questioned by many across the world because it is commonly viewed as a recreational activity. Many residents have a problem with the dangers that come with hunting. Not to mention, as time goes on, society seems to feel differently about animals and how they should be treated. One of the biggest debates is the harvest of white tailed deer. All over the United States, white tailed deer thrive because of the few predators that feast upon them and the large forests and habitats that these deer can flourish in. However, as buildings and subdivisions pop up left and right decreasing the white tailed deer natural habitat, the debate grows stronger. The heart of the debate is centered around ethical issues, human and deer conflicts, safety, and the benefits hunting has on the economy.
Not only will this be catastrophic for the humans, but animal and plant life will suffer too (“Global Warming” 4, 10, Than 1-4). The oceans will become more polluted and warmer which will cause fish along with coral reefs will die (“Global Warming” 4). The heat will bring animals to extinction; their migration patterns will be altered, change their diet, and force them to live in different locations in order to find a suitable climate (Than 1). Additionally, the warming will hurt the crop production. Crops have a very specific range of temperatures they should grow in order to maximize their yield, and if the earth is going to be above the temperature then crop yield will suffer. Projections for the year 2050 show...
In my hypothesis I previously believed that the lower the lower the pH level the more seeds would germinate, due to the extra hydroxide. But more seeds actually germinated in the pHs closer to neutral. Some problems in the experiment was the towel drying out and the seeds no longer absorbing the pH, rewetting the towels with the solution could prevent this. Some experimenter errors that occurred is the seeds falling out of the towel which resulted in seeds germinating or not germinating. Also, air getting into the bags and drying out the towel faster could have been prevented by making sure the bag was closed. Lastly, the seeds did not get put in the bag exactly like the previous time which could have affected the germination. To improve this lab, measuring out the same amount of solution for each pH could have made it more accurate. To further this experiment we could have had another set of seeds in the same pH solutions but in the sun to see
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Stowe uses different perspectives of people who were affected by slavery and what they did to influence the abolition movement. Uncle Tom’s Cabin starts when Mr. Shelby, a plantation owner, sells two of his slaves: Uncle Tom and Henry. The book follows the perspectives of Uncle Tom and Henry’s mother, Eliza. Eliza heard of her young son’s fate and decided she needs to get him safe. During Eliza’s escape, she meets up with her husband, George Harris, who had run away a couple of days before. Both decided that their best option was to escape to Canada. A bounty man, Tom Loker, hunted Eliza and her family that led to George pushing Loker off a cliff to protect his wife and son. Eliza worried Loker would die so her and her husband rescued the man and took him to a nearby Quaker community.

can cause a lot of carbon dioxide to be released. Every time we burn fossil fuels, we release more
The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth.
