Shark Reseachers Study Oil Impact

http://articles.cnn.com/2010-06-28/us/oil.spill.sharks_1_shark-population-larger-sharks-tiger-sharks?_s=PM:US

Summary:

The oil spill has been effecting the sharks very dramatically. Reacher Niel Hammerschlag, who has been studing sharks for a decade now, is tagging sharks in the Gulf to see their migratory and behavioral patterns. Sharks are pretty much at the top of the food chain and they pretty much eat everything under them, if they never touch the oil something they might eat might of been hurt by the oil. This will make the sharks die because they won't be eating as much. The way that sharks breathe is they "take in the water, the water goes over their gills and they extract out the oxygen." So if the sharks are in the oil it will be extremely hard for them to breathe. In the Gulf there are spots where people are not allowed to fish, because we don't want the people to get sick. If we don't get this oil cleaned up soon who knows what will happen to all the sharks.

Opinion/Reflection:

I think that it is a horrible thing that happened in the Gulf. Also it is pretty cool to see how some people are taking things into their own hands, and making sure that we are doing everything that we can, to try and see if the sharks are being effected by the oil. Its very interesting to see that if one thing gets damaged in a food chain how the rest of it will be effected. I hope that we can have the oil cleaned up fast so the food chain will be able to go back to normal!

Questions:

1. What is the name of the guy who is tagging these sharks?

2. How long has he been studing sharks?

3. How do sharks breathe?

4. What do you think we can do to help these sharks?

Population Increase From Unauthorized immigrants

Unauthorized population would soar if birthright citizenship repealed.

http://esciencenews.com/articles/2010/09/08/unauthorized.population.would.soar.if.birthright.citizenship.repealed

Summary:

If the US took away the citizenship for US born children of unathorized immigrants the population would increase at minimum of 5 million over the next 10 years. Even if we completley stoped illegal immigration these numbers would still add up. When the passage of House-introduced Birthright Citizenship Act ( the deny of citizenship to children who were born from unauthorized immagrants), was over looked it showed that it would increase from 10.8 million to 16 million by 2050. It was also found that in 2050 the share of US children that are unautherized would double from .02 (now) to .04 (2050). Other cases would be denying citizenship to a child who has 1 unautherized parent. By the third generation, 6.3 million US born people would be unauthorized even with two of there parents being authorized because of the birthright citizenship act. "What is less commonly understood in the current debate is that repeal of birthright citizenship would set in motion the creation of a self-perpetuating class of unauthorized immigrants," said reports coauthor, Michael Fix.

Opinion / Reflection:

I really had no idea about how much the birth rate of immagrents could expand. It Suprised me to see how many unauthrized US born people there could be in 2050. What i never really thought about and looked at in the long run was how by the third generation a child could have two US born parents but still be unauthorized.

Questions: (3-5)

1 - What is the act called that is denying citizenship to illegal immigrant children who are born in the US?

2 - By how much will the percent of unauthorized children be in 2050?

3 - What was the other case in which children still are unautherized?

4 - By the next decade how much will the nation expand by in unauthorized people at least?
