BIODIVERSITY

Faith, Daniel P. "Biodiversity." Stanford Enciclopedia of Philosophy. Stanford University, 2007. Web. 21 Jan. 2010. .


--Biodiversity is all species, ecosystems, and all living things that create this planet.Biodiversity is the process of which the every works and how they develop over time, and through out their environment needs, Biodiversity also links to the DNA and all humans, because there is a lot of diversity between the human population, if their wasn't any diversity at all we all be equal and we wouldn't be able to develop properly. All living things are important in a certain way to maintain an equilibrium and to maintain the environment flowing as is suppose to.

--Human activity has being one of the causes that extinction is happening, they say that current extinction rate is now approaching 1,000 times the background extinction rate( before humans exist) and its going 10,000 times the background extinction rate during the next 100 years. As we see the contributions that humans are making to the extinction of the earth one-third to two-thirds of all species that live in this earth are going to die.



The International Union for Conservation of Nature (IUCN) notes in a video that:

* 1 bird out of 8,
* 1 mammal out of 4,
* 1 conifer out of 4,
* 1 amphibian out of 3, and
* 6 marine turtles out of 7, are all threatened with extinction

A new global study shows that 90% of all large fishes in the world have extinct thanks to industrial fishing in the last half century.

-- A report shows that 30% of all natural world have being destroyed by humans. The ecosystems have become more difficult to help to survive. Many animals have being dying and its getting harder to repopulate these animals. Some animals that have being affected by this are: The tigers with a 95% probability of getting extinct by 2010, the lions have being decreasing in Africa compare to the 1980’s when there was 200,000 lions. The number of Rhinos have also decrease by the humans that want their horns and now they have no protection, The vultures in India in the past 12 years the population if this specie have crash by 97%, by eating the drug animals that the farmers have, and they have poison the vultures. The polar bears have die thanks to the pollution, oil exploration, hunting, as well as climate. And many other animals have die with the negligence that we have by not taking care of the animals and all species that surround us.

BIODIVERSITY AND GLOBAL WARMING

http://www.birdlife.org/action/science/sowb/pressure/46.html


The Earth is undergoing profound changes to its climate. There is now little doubt that this results from human activities, mainly the burning of fossil fuels. These recent changes are different because they are taking place faster and are unlikely to be reversed by natural processes.The effects of climate change on biodiversity are far-reaching and operate at many different levels – from individuals to ecosystems. At the species level, climate change affects particular species in different ways. It may alter their distribution, abundance, behavior, penology (the timing of events such as migration or breeding), morphology (size and shape) and genetic composition.

Socratic Seminar

In the article Farmer in Chief I learned that America is trying to closed down the farms and putting products that are not real anymore, like the fruit that we eat and the vegetables we put in our food. Now days people prefer eating fast food than taking something to work or school, we want something fast and cheap. What stroke me the most was that even though our health is bad, we still prefer unhealthy food than buying something that is going to make us better. In the article i read that four of the top 10 killers in America today are chronic diseases linked to diet: heart disease, stroke, Type 2 diabetes and cancer.

To stop this from happening we have to go to the doctor, but since the government is charging to much we dont have the money to go, and if we go to the doctor we dont have money to buy healthy food wich means that we have to eat fast food in order to go to the doctor, but what we want is to be healthy, but either way we are not getting there, so we prefer to stick with the fast and cheap.

Also in this article we see that we are using chemical fertilizers when we can use the sun, we are waisting money that we could use in something else, and we are paying farmers to grow corn soybeans and rice, when we could be paying for vegetables and fruits. With the meat we are also doing really bad, we are getting stuff that wasn't feed well and the price goes lower, because the cost to feed this animals was cheap also. But people buy it because they don't know where it came from, they just care for the price.

If we keep doing what we are doing with the food, in a few years we are going to be having wars not for land but for the food that we are letting go by not taking care of it.

What is one thing in the natural world that your curious about?

Something that I'm curious abouts about is how the animals have to eat each other in order to survive. Also i have heard that there are fishes that even eat the excrement of the other fishes just to maintain the water cleaner and healthier. I want to learn more about the pants and do they help other plants, and the animals around them. Another thing that im curious about is the ecosystem and how it works. how is it that the most minimal thing helps create a better world, and what can we do to maintain the world like that.
