Animal Liberation
Peter Singer describes how most humans are speciesists. This means most humans allow that their taxes to pay for the experimentation of other “lower” species as long as they are not being performed on their own kind. The scientists save their conscience by saying that animals are equipment used in their experiments.

Cures and Creatures Great and Small
People against animal experimentations argue that it’s a not moral, evil action that should be stopped. Jeremy Bentham asks “can they reason, talk or feel pain?” Answer is yes they do and can. Scientists that use rats say they have a similar nervous system to humans. Pain is an evil that should not be placed on a child, adult or animal. People that wish to continue experimenting say that society has an obligation to minimize harm and to maximize benefits. Stopping would result in bad consequences. Even though scientists try to minimize pain by using pain killers, those sometime interrupt with results so they can not always be used. They say the benefits out weigh the suffering of animals. Experimenting produces good results even at the cost of inflicting pain on animals.

Article: Alternatives: Testing Without Torture
Alternatives to animal testing are more efficient and reliable becuase there are no species differences. They take less time and are generaly less costly.
Types include embyronic stem cell test, which uses mouse cells to assess the toxicity of embryos, 3T3 Neutral Red Uptake Phototoxicity Test, that uses culture grown cells to test sunlight irritation on skin, EpiDerm test, that replaces rabbits for the skin corrosion test.

Article: Guilt-Free Beauty
In 2001 cosmetic industries were not required to test their makeup before it went to the shelf, but they were urged to do so to protect the safety of humans. Rats and mice are a majority (85-90%) of the animals used to test make up on. Rabbits, Guinea pigs and hamsters come in second, and then dogs, cats and non human primates are 1% of the tested animals. 73% of the testing done on animals are done for consumer testing.
Although animal testing has been reduced almost 90% since 1980, there is still alot more that can be reduced. Companies mainly do not switch to other testing methods because its cheaper on animals, and the lack of confidence in testing other ways.
Replacement, Reduction, and Refinement.
Other testing options:
Caenorhabditis elegans- reliable in testing toxicity. Cultured human skin- actual human skin grown to test toxicity. Eyetex- eliminates Draize eye test by using in vitro (test tube). Skintex- In Vitro that measures human skin irritancy. Corrositex-measured skin corrosion and eliminates animal testing all together, synthetic skin model.

Article: Going Green The Beuauty industry is finally realizing that consumers don't just want organic coffee and carrots, they want ethical cosmetics, too.
Going green in the cosmetics industry is more expensive but with the rise in ethical consumers it is in high demand. Going green means using biodegradeable products, but also using ethical means in making the cosmetics, like no animal testing. Companies such as Suki Kramer (Suki Pure Skin Care) and Rich Hippie (perfume) are cruelty free when testing their cosmetics. A vegan friendly cosmetics line has recently been made called B Never Too Busy To Be Beautiful. Yes, it is more expensive, but it is worth it.

Article: Ask the Doc; What are alternatives to animal testing?
Non animal testing methods are more ethical and translate better to humans. There are many differences in biology, chemistry and physiology when testing on animals.
Selective Formulation- using previously tested ingredients eliminates the need to test them again, works well when making a new line of products.
Human Cultures- Epiderm and EpiSkin are human skin cells that are grown in a test tube. They mimic human skin. Testing cosmetics on these is much better than rabbits.
Corrositex- another test tube option that is easy to read the results by color change.
EpiOcular- skin cells created to mimic the eye cornea, replaces rabbit eye irritant test.
Physiological chip- 1 x 1 inch square of cells that mimic the complex functions of the human body. It can test harmful and beneficial effects of drugs.
Cellular tests- measures white bloog cell response to chemicals

Article: Product Testing: toxic and tragic
There are many different test performed on animals, including rats, Guinea pig and rabbits. The first one is the acute toxicity test where the chemical or product is forced down the animals throat at high doses and seeing what the reaction is. The second test is the Lethal dose 50% test where they force feed numerous animals till 50% of the animals die. The 3rd test is the Draize eye and skin corrosion test which drips substances into the animals eye or shaved head, which has been proved to be severely inaccurate, like the previous 2 tests. Even though these tests are inaccurate they are still performed. For testing products the Food and Drug Administration "urges cosmetic manufacturers to conduct whatever tests are appropriate to establish that their cosmetics are safe... and does not specifically mandate animal testing for cosmetic safety." So they are not forbidding the inhumane testing of these little animals. There are much more accurate tests out there being developed. Companies could use cell and tissue cultures that mimicks the human skin, or structure activiity relation ship models.

Spring Break RAFT
I didn't go any where for spring break. I stayed home and hung out with my friends a lot of the time. On the first Sunday of break I went to Disney Princess Wishes on ICE. It was the cutest thing. I love Disney. I also watched Disney movies with my younger sister while I babysat her. I was with Dani R. a lot, sat at her house and waited for people to pick us up (mike k). I would try to go to bed at a reasonable hour but I would always get late night phone calls from people and an unreasonable hour. But it was OK. I enjoyed them. My friends and I went to Target a lot because there is not much else to do in this town I like to call Oakdale. I practiced my driving because I have my Drivers Test this upcoming Thursday (yaay). Spring Break was pretty fun. I have no complaints. I just really like hanging out with my friends and doing whatever we wanted. I'm really excited to come back to school for tri 3. I feel like we just started the school year though. It went by so fast. Some of the teachers are saying that we should be taking on more responsibility since we are now closer to being Juniors than we are Freshman. Well I don't feel that way. There has not been that big of a transition. My classes are still the same with the same teachers, and even in the same order. tri 3 should be just as much fun as the rest of the year. =]

Problem Solution Essay
Kin Hubbard once said, “Don’t knock the weather. If it didn’t change once in a while, nine out of ten people couldn’t start a conversation.” This quote is very true today because there has been much talk of weather in recent years due to the change in the Earth’s climate. People are seeing a definite change in our climate, and not for the better. This is a slow change but is affecting us greatly. We know there is a change because of the increase in temperatures and the rise of CO2 gases being omitted into our air, which are creating a greenhouse effect in our atmosphere. These increases are due to humans and our uses of fossil fuels. The continuation of the change in the climate will be harmful for our environment. People need to make small changes in their lives and take initiative to start the process of reversing this change.
It is hard to ignore the change in our climate when the facts and data are out there for us to see. The top ten highest temperature years have all occurred since 1990. According to the US Environmental Protection Agency, the top 5 hottest years have been 1998, 2002, 2003, 2004 and 2005. EPA states that during the 1990’s the surface temperature of the earth raised 1.2-1.4 degrees Fahrenheit. Judith Curry says in an article about hurricanes that since 1970 the sea temperatures have increased an average of 1 degree. This has resulted in 50% more tropical storms and hurricanes in the past 30 years, proving that this change is happening. Some say that hurricane Katrina was a result of this increase in temperature. Between 1961 and 1997, 890 cubic miles of glacier ice has melted. According to Global Warming Myths and Facts, scientists predict that up to a quarter of the global mountain glacier mass could disappear by 2050, and up to half by 2100. They also say that Carbon Dioxide is normal for our atmosphere, but the norm is 180-300ppm. Right now there is 380ppm of CO2. That is 25% more Carbon Dioxide in our atmosphere. All of these facts and statistics prove that the earth’s temperatures are rising and it is changing.
The largest contribution to the increase in temperature and climate change is humans. Scientists say that we are the leading cause. We do things that significantly add to the amount of gases that cause the greenhouse effect and make our temperatures rise. For example, EPA for Kids warns that everyday activities like watching TV, turning on a light, driving a car, and using a microwave omit bad greenhouse gases into the air. EPA also adds that some of these activities include the burning of fossil fuels and biomass to make these things run. There are many fossil fuels that are being omitted into the air more then normal, like coal, oil and natural gas. This produces aerosols that omit more heat into our atmosphere. This increases our temperatures. Global Warming Myths and Facts also says that an increase in temperature is also do to the fact that more and more deforestation is occurring, putting more CO2 into the air then ever before. This increase of CO2 is a major cause of the rising temperatures. NASA cautions us by saying that an increase in land use and CO2 production its contributing to the rising temperatures. Everything is all linked and since we are increasing our activity and use of fossil fuels, it contributes to the increase in temperature.
The rise in temperatures, caused by humans, is contributing to the change in our environment. If a rise in sea temperature continues, glaciers will melt and the sea level will rise, resulting in climate changes and dangers for the coasts. The rise in temperatures is resulting in different season patterns for parts of the world. So, humans are contributing to the rise in temperatures, which in turn contributes to the change in our environment.
There are many things humans can do to stagger the increase of harmful gases and fossil fuels into the atmosphere. And if enough is done we can stop these harmful gases and save our climate. The United States Environmental Protection Agency advices us to take small steps in helping our environment by decreasing the harmful gases sent into the air. First, you can you Energy Star Label products on all appliances, like refrigerators and microwaves. It is also important to use them for lighting. They say to clean your heating and air conditioning filters so they do not submit bad toxins into the air. Instead of using harmful coal as an energy source, use Green Power, it is eco friendly. And one of the most helpful ways is to recycle. That way you can save the earths natural resources, because unlike most believe, they are not an unlimited resource.
There is a change in our environment and it will be harmful for us if it continues. Our earth is increasing in temperature and has gotten hotter in most recent years. The environment is an unstable thing and humans are not helping it by increasing the amounts of harmful gases and fossil fuels. The change in our environment is due to the rising temperatures. Humans are contributing mostly to this problem by not being environmentally friendly with their energy resources. Fixing the problem can be easily done, people just need to take the initiative and do it.

Day 5. Climate Change
PROBLEM:
There is a deffinate change in our climate, but not so drastic that everyone needs to be afraid. The change is that it is warming, which is called global warming. I am going to prove there there is a change from previous generations, and not for the better. There should be some change in our society to stop these changes. I am takeing a moderate position on the issue.
EVIDENCE:
1900, the average surface temperature warmed by about 1.2-1.4 ºF.
1970s, the average surface temperature has warmed about 1 ºF.
The Earth’s surface is currently warming at a rate of about 0.32ºF/decade or 3.2 ºF/century.
The five warmest years over last century have likely been: 2005, 1998, 2002, 2003, 2004.
The top 10 warmest years have all occurred since 1990.
//US Environmental Protection Agency. Temperature Changes//
A rise in sea level as the oceans warm and expand, glaciers will melt, weather patterns will change, animals and plants will shift to new habitats.
//TIME Magizine2//
Though natural amounts of CO2 have varied from 180 to 300 parts per million (ppm), today's CO2 levels are around 380 ppm. That's 25% more than the highest natural levels over the past 650,000 years. Increased CO2 levels have contributed to periods of higher average temperatures throughout that long record.
Between 1961 and 1997, the world’s glaciers lost 890 cubic miles of ice//Global Warming?//
By burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising.
//An Inconvinient Truth. By Al Gore//
Worldwide sea surface temperatures have increased by about 1 degree since 1970, resulting in about 50 percent more tropical storm activity than normal.says Judith Curry, a professor of atmospheric sciences at the Georgia Institute of Technology//Hurricanes//
The Earth has warmed about 1ºF in the last 100 years. And the four warmest years of the 20th century all happened in the 1990s //EPA for kids//
CONTRIBUTING FACTORS:
human activities have substantially added to the amount of heat-trapping greenhouse gases in the atmosphere. The burning of fossil fuels and biomass (living matter such as vegetation) has also resulted in emissions of aerosols that absorb and emit heat, and reflect light.//US Environment Protection Agency. Climate Changes//
The most respected scientific bodies have stated unequivocally that global warming is occurring, and people are causing it by burning fossil fuels (like coal, oil and natural gas) and cutting down forests.
People are causing global warming by burning fossil fuels (like oil, coal and natural gas) and cutting down forests. Scientists have shown that these activities are pumping far more CO2 into the atmosphere than was ever released in hundreds of thousands of years.
//Global Warming//
Scientists are concerned that human activity, such as increased carbon dioxide production and land use, may have begun to affect Earth's climate//NASA//
Watch TV Use the Air Conditioner Turn on a Light Use a Hair Dryer Ride in a Car Play a Video Game Listen to a Stereo Wash or Dry Clothes Use a Dish Washer Microwave a Meal //EPA for kids//

The burning of fossil fuels and biomass (living matter such as vegetation) has also resulted in emissions of aerosols that absorb and emit heat, and reflect light.//US Environment Protection Agency. Climate Changes//
The most respected scientific bodies have stated unequivocally that global warming is occurring, and people are causing it by burning fossil fuels (like coal, oil and natural gas) and cutting down forests.
People are causing global warming by burning fossil fuels (like oil, coal and natural gas) and cutting down forests. Scientists have shown that these activities are pumping far more CO2 into the atmosphere than was ever released in hundreds of thousands of years.
//Global Warming//
Scientists are concerned that human activity, such as increased carbon dioxide production and land use, may have begun to affect Earth's climate//NASA//
now through population growth, fossil fuel burning, and deforestation, we are affecting the mixture of gases in the atmosphere. Energy that makes cars run and much of the energy used to light and heat our homes, comes from fuels like coal and oil – fossil fuels. Burning these fuels releases greenhouse gases.
Watch TV Use the Air Conditioner Turn on a Light Use a Hair Dryer Ride in a Car Play a Video Game Listen to a Stereo Wash or Dry Clothes Use a Dish Washer Microwave a Meal //EPA for kids//
SOLUTION:
There are small steps everyone can take to slow the progress of the climate changes.
- Use Energy Star light bulbs.
- Look for the Energy Star Label when you shop for appliances.
- Clean your heat and AC filters so they dont submit toxins and dirt in to the atmosphere.
- Use Green Power. An eco friendly engery source.
- RECYCLE

Day 3: Tartan Problem
Tartan Problem
:Crowding in the hallways
Evidence
-Studends cant get through the hallways
-I see many people not moveing to where they need to be
-the school is over crowded for its right amount of students
Contributing Factors
-the short passing time
-people stop to talk to friends and gather around the stairs
-school is over populated
Solution
-Make a new school rule against lingering and blocking hallways.
-Make passing times longer so people can get to classes on time so the crowding in the hallways won't be such a problem.

Day 1
My friend is having trouble keeping up with the class. You suspect that bad study habits may be causing her grades to drop.
I would be very worried for my friend. She is usually a very good student. I would aproach her and ask what is wrong. Also, ask if there were any problems at home and if there was anything i could do to help. If there was something else preoccupying her mind, like a friend problem or family problem I would do my best to help her through anything. If the problem was that she simply just didnt understand the material I would become her personal tutor. I hate watching my friends struggle when there is something I can do to help. After all of this I would hope that her grades increase and her problems go away.
