There are many causes of global warming. Since 1850, earth’s temperature has increased by about a degree or two because of the greenhouse effect . The greenhouse effect occurs when heat generated by sunlight hits the earth and is intercepted by certain gases in the atmosphere, preventing the heat from radiating away from the planet and into outer space. These gases are carbon dioxide, water vapor, nitrous oxide, methane, and chlorofluorocarbons . The reason these gases build up is that Carbon Dioxide can’t be removed out of the air due to deforestation . Deforestation causes plants and vegetation to die. The reason that this is a problem is because plants, trees especially, remove harmful gases out of the air. If the vegetation isn’t here to take the gases out of the air, the gases will continue to build up, and create a blanket around the earth.
Since the nineteenth century, carbon dioxide concentrations have increased by over thirty percent. When the levels of carbon dioxide rise or fall in the atmosphere, the temperature changes with them. This is known as the greenhouse effect, global warming, or global climate change. Research indicates that human activities have a measurable cause in climate effects. However, it is difficult to prove that the earth’s surface and lower atmosphere have gotten warmer from the greenhouse effect rather than an unknown process of natural climate change. Driving cars, burning gases, and burning down forests are just a few ways that humans can cause damage to the earth. Since humans are part of the reason for global warming, everyone should be willing to help stop this process. Simple changes in lifestyle such as recycling paper and reusing water bottles can be a help. There are many small actions that can help stop global warming and reduce global climate change.
Global climate change can have many serious impacts, not just on the earth, but on animals. One of the worst impacts is the melting of polar ice caps. The warming is predicted to be up to 3 times greater in Polar Regions as to tropical areas. When the white ice melts in Polar Regions, the exposed ground or water is darker in color, and absorbs more solar radiation. This adds on to the temperature increase. Also because of the ice melting, sea levels will rise, and may make low lying land become flooded. This puts polar animals in danger, such as penguins, seals and polar bears. In addition, the strength of storms could also increase, making hurricanes and tornadoes almost 10 percent stronger, due to a raise in ocean temperature. Rainfall patterns are expected to change, as well as animals’ hibernation patterns. Research shows that about 25 percent of the world’s species could be at high risk of irreversible extinction. One more effect is an increase in carbon footprint. There are many ways to help stop these harmful effects of global warming. Organizations such as World Wild Life Funds (WWF) are a great way to get involved. By donating to this organization or others like it will help the animals in danger and also help reduce pollution.
Recycling can be a huge help in putting a stop to global warming. Today, many Americans have become familiar with the phrase “reduce, reuse, and recycle”. Reducing the amount of resources we use can be a big impact. Walking or biking rather than driving can conserve gas and prevent harmful gases from radiating into to atmosphere. Studies show that the US is running out of landfill space. The down side of recycling is the cost. Still, environmentalists are committed to recycling . I believe recycling is totally worth the effort to support our earth. Recycling helps reduce the amount of pollution and conserve the earth’s resources. If we don't recycle, we could run out of resources and we wouldn’t be able to rely on our earth for much longer. The more we conserve the more the earth will have positive effects.
I got some of this information from my intellegent brain, and some from :
"Greenhouse effect." World of Scientific Discovery. Ed. Kimberley A. McGrath and Bridget Travers. Online ed. Detroit: Thomson Gale, 2007. Student Resource Center - Gold. Gale. John Carroll School. 9 Oct. 2009
issues in global warming are whether the cost of recycling is worth its cause.
I believe it is worth it because recycling conserves the earths resources. If we want the earth to last we need to save the resources.
Another issue is if global warming is caused by the greenhouse effect or by an unknown natural process. I personally believe that it is cause by pollution, because of scienctific research and proof.

Globalization is the increasing interconnectedness of people and places through converging processes of economic , political , and cultural change. Those who are pro-globalization believe that wealth will “trickle down” from rich countries to poor countries. They also believe it will spread the benefits of new ideas and new technologies to all nations. One organization that loans money to nations so they can invest in business is the World Trade Origination. On the other hand, those who are anti-globalization say it is not fair, because the richest 20% of the world’s people consume 86% of the world’s resources, resulting in inequalities between “haves” and “have nots.”
Use the CIA Factbook to answer the following questions: In Luxembourg the life expectancy is 79.33 years , the infant mortality rate is 4.56 deaths per 1000 live births, the literacy rate is 100%, and the TFR is 1.78 . In Libya the life expectancy is 77.26 years , the infant mortality rate is 21.05 deaths per 1000 live births, the literacy rate is 82.6%, and the TFR is 3.08 .
We often categorize nations as being “developed” or “developing” nations. Vietnam and Mexico would be considered developing nations; Japan and Canada are developed nations.
The current world population is over 6.6 billion people. The number that measures how many children the average woman in a nation will bear is known as the total fertility rate , which is abbreviated as TFR. When this number is exactly balanced , then the population stays the same; if it’s higher, the population goes up, and if it’s lower, the population decreases. The population is growing fastest in _developed nations.
A population pyramid that is shaped just like a pyramid -- wide on the bottom and narrow at the top -- shows a country whose population is growing. If it is shaped more like a vase or a soda bottle, that nation’s population is staying about the same. Younger people are found at the bottom of the pyramid, and males are found on the left hand side.
When discussing migration, people who are entering a country are known as immigrants, and people who are leaving a country are known as emigrants.
People leave their country for many reasons. An example of a push force is famine and war, and an example of a pull force is job opportunities and good health care . If a nation’s net migration rate is a high number, it means more people are leaving the country than are arriving.
Some people feel very strongly in their pro-globalization opinions, while some anti-globalization advocates have different beliefs. It’s likely that the truth lies somewhere in between. What do you think is the “middle ground” in this argument? Be sure to provide evidence for your opinion.
Both pro globalizers and anti globalizers over exaggerate. I think the "middle ground" is to help developing countries become more industrialized without doing too much to fast. Economic globalization is unavoidable. This way, countries could become more equal with having a very unstable economic system.
