Acid Rain

1. What gases are the major cause of acid rain? Gases that are the major cause of acid rain are sulfur dioxide and nitrogen dioxide.
2. Where do most of these gases come from? Most of these gases come from burning fossil fuels by coal burning power plants, factories and automobiles.
3. Describe a few negative effects of acid rain. A few negative effects of acid rain are it makes water toxic for clams, fish, crayfish, and other aquatic animals. It impacts other animals like birds. It damages forests because it steals its nutrients. It also makes them unable to withstand cold temperatures.

"Fracking"

1. What is the purpose of "fracking?" The purpose of "fracking" is when water and chemicals are injected into the ground at high pressure to break up rocks and release gas that is trapped there.
2. How is "fracking" done? "Fracking is done by drilling natural gas and water into wells.
3. Why are people concerned about "fracking?" People are concerned over "fracking" because they think it will contaminate their drinking water. Also, one "fracking" incident led to an eruption of a volcano that killed at least 13 people and displaced 30,000 people.

Flood Controls

Attempts to control rivers have increased because human technology has progressed. Humans should continue to attempt to control rivers. As it says before, human technology is progressing, and the new technology can help us control the floods happening in hopefully not harming ways. If humans have a successful attempt to control the rivers then people around the rivers wouldn’t have to wait until certain times to plant their crops. The Egyptians controlled their rivers, and with the technology we have today we should be able to successfully control rivers. If humans don’t attempt to control rivers, some farmers would only be able to plant crops one season. Thus decreasing the amount of food that we have. Another good reason for humans to control rivers is that a low flood could lead to famine and a high flood ruins irrigation works. Attempts to control rivers that won’t really harm the environment is natural levees. These are usually the first solution to the flooding problems. Comparing this to the Nile River,  the Nile River didn’t have any flood control. The Nile River flooded ruining irrigation, and this wouldn’t have happened if they had flood control. As you can see, humans should use their technology to control the rivers.

Global Warming Graph

1. What is the horizontal axis showing, and what is the range of values? The horizontal axis shows years. The range of values is 155.
2. Is present day on the right, or the left? Present day is on the left.
3. What is the vertical axis showing, what are the units, and what is the range of values? The vertical axis is showing the temperature in Celsius. The range of the values is 1.
4. The graph was created from data that was gathered.  Does the web page state where the data came from? The webpage states that the data comes from http://data.giss.nasa.gov/gistemp/

What website do you believe and why?

I believe global warming facts #1 (http://news.nationalgeographic.com/news/2004/12/1206_041206_global_warming.html) because global warming is not fake. Scientists can show statistics that it's real like that the temperature has climbed 1.4ºF since 1880. The other website, global warming facts #2 (http://kutwrite.hubpages.com/hub/Global-Warming-Fake-01), doesn't seem logic. They don't share as many examples as the other website. Also, global warming has been talked about for a long time. Why would they keep the lie of global warming going this long? What does it prove? This is why I believe global warming facts #1 over global warming facts #2.

Soil

About ninety-eight percent of people do not obtain most of their necessary living items from the ground.

The population has increased by three hundred percent in the last one hundred years.

It seems weird that ninety-eight percent of people buy their food from grocery stores from grocery stores and only two percent supply the food they buy for them. It doesn't seem like the two percent of people would be able to feed ninety-eight percent of people. If at least half of the ninety-eight percent of people grew something, more people would be able to be fed. I find it interesting that the population has increased by three hundred percent in the last one hundred years. With the diseases and lack of people growing food, I thought it would be less. If more people grew food, I believe the population would have increased by a lot more.
