The spotted owls are threatened due to loss of habitat, and the habitat that they have is being taken over by barred owls. But what specifically is the cause of this? Is there not enough food for both owls in this habitat? Not enough shelter? Are there any other suggested methods to fixing this problem?
Scientists say that these deceased Indians are needed for research that could benefit the health and welfare of living Indians. But just how many dead Indians must they examine? Nineteen thousand? There is doubt as to whether permanent curation of our dead really benefits Indians. Dr. Emery A. Johnson, former assistant Surgeon General, recently observed, "I am not aware of any current medical diagnostic or treatment procedure that has been derived from research on such skeletal remains.
Margaret Wente takes a controversial position in her article Polar bears don’t need us to save them by providing an optimistic outlook for the fate of the polar bear population. Wente attempts to convince her audience that scientists are merely “making a political point, not a scientific one” (par.7) when they claim that the polar bear population is declining and will be “dead by a certain date” (par.7). She emphasizes that the best way to help the polar bears is to stop harassing them, and for scientists to shift their focus back to conducting core research. Although, Wente makes an effective appeal to her audience’s emotions, her overall argument is compromised by poorly evidenced claims, and a weak appeal to authority. The effect of global warming on the polar bear population and lack of substantial measures to stop the extinction of this species has resulted in public outcry in recent years.
Bio 100 Homework due 11/05/12 Name : Nicholas Oliveira Go to the website on cheetah conservation www.Cheetah.org and read the following sections under the tabs About Cheetahs: Intro, Genetic Diversity, & Race for Survival 1. Why are cheetahs endangered? Our attitudes and misconceptions about these species have led to their endangerment because many people deal with their fear by eliminating predators. 2. What are the 5 most common causes of extinction?
All the Yes points 1.Temperature from history 2.Sea level 3.Weather 4.Because people are losing lives and our climate is changing 5.Many factors involved. All the No points 1.The scale of the problem 2.The need for oil 3.Polar Bears and other species are threatened with extinction 4.Nature will adapt better than we will 5.Kids will have to eat poo Global Warming is not an issue Yes because... No because... Temperature from history If people were able to look at the temperature data for the past 200 years, that data would show that the temperature levels on the planet have always fluctuated. That same data will show that it is human beings who are causing the problem. Pollution
In this argument, the author attributes the decline in arctic deer populations to their being unable to follow their age-old migration patterns across the frozen sea. The reason the author provides is that the arctic deer survive by traveling over the frozen sea to find plants on which they feed ,and that recently it is wildly reported that globe warming are causing the ice to melt ,plus at the same time according to reports from local hunters the deer populations are declining. By Examing the line of reasoning through which the author draws his conclusion, we can see several majoy logical fallacies that make it far from convincing. The author provides no evidence to prove the atctic deers’ being unable to follow it but present a fact, if we can say so, that gobal warming trends have caused the sea ice to melt. The reliability of the cited fact is doubtful, let alone the justifiability of the assumption that the Canada’s arctic region where the arctic deer reside has also experienced the sea ice melting.
Two decades after Animal Liberation was first published animal activists can cite the move away from testing cosmetics on animals, a reduction in number of animals used in laboratory animal experiments, and efforts in Europe to make livestock and poultry production less stressful. Singer believes it is important to see these reforms as stepping stones on the path to further goals, not as the be-all and end-all of the
Pre Lab Questions: 1. Explain the reasoning behind the classification of biological hotspots. * A biological hotspot is an area that is rich in biodiversity but is being threatened of extinction 2. What reasons are there for classifying Madagascar and the Indian Ocean Islands as biological hotspots? * Madagascar and the Indian Ocean were once a place of high plant and animal diversity and population however, in the last 1500 years people have come into this untouched environment impacting these species due to their lack of knowledge on human involvement.

It would interfere with millions of migratory birds that feed on its tundra plains. It would kill plants and animals that are native to the Beaufort Sea area and the environment would take two decades to recover. If there were a major oil spill, it would decades for the ecosystem to recover, since so many organisms would be contaminated and eventually die. Remember the 1989 catastrophe when the Exxon Valdez spilled 35 million gallons into Prince William Sound? The
