It has been long accepted that an asteroid killed off most of the life on earth 66 millions years ago but now there is evidence that volcanic activities which started before the asteroid strike and continued long after, may have contributed to the mass extinction. There is disagreement among the scientists as to whether the volcanic activity was the main cause of the extinction or whether in conjunction with the asteroid hit helped to kill off sixty percent of all life on earth. The Deccan Traps in India is where the scientists have studied the violent irruption of the volcanoes that may have helped cause the extinction.
From a personal point of view it is important for people to understand that mass extinctions have happened in the past and they can happen again. There is little we can do about volcanoes but I do know that scientists are monitoring asteroids that might one day crash into the earth. In the future we might be able to do something about asteroids.
The article provides evidence for different possibilities about the mass extinction of the dinosaurs and other life 66 millions years ago but the evidence is not conclusive as to the exact cause of the die off.

    I chose to read Naoko’s review of the article “Dino Double Whammy” by Stephen Ornes. A few that stood out to me were that the mass extinction event killed off 60% of all life on earth. Another thing that stood out was the volcanoes could have played a much bigger part in the extinction than was previously thought. Something else that stood out to me was that the extinction was 66 million years ago and to me that just seems like a really long to me and I’ve also heard from other sources that we are long overdue for another. One thing that could have been handled better in this review was she could have mentioned the expressions names in her review just so we know who is saying what on the topic. Another thing that could have been done better is talk about the things that could be used to stop the asteroids from hitting the earth in the future since it is mentioned in the review that this is happening. One thing that stood out to me was that another mass extinction could happen again and if that happened the loss of life would be extremely high.

  3. For my current events assignment this week, I chose to read Niako’s review of, “Dina Double Whammy.” One thing that I thought she did very well was give background information on the topic, first explaining the well known theory of how the dinosaurs went extinct and then bringing up the opposing view point that the article gave. I also like how the review gave a good real world connection, saying we need to learn about our past so we can be prepared for what could come in the future. Finally, there were no grammatical errors in the review.
    Although Naoko had a very good review, I thought there were a few things she could’ve done to make it better. First off, I would have liked to seen her provide some facts or quotes from the article to give us an idea of what side it was taking, as this was very unclear. Also I would have liked to seen her expand on some of her ideas, for instance she mentioned the fact that we can track asteroids, but it would’ve been nice to know who was doing this and how.
    Finally, what I thought was amazing is that something like what happened to the dinosaurs could happen any day to us, and it is really eye opening that we could be extinct very soon.

    I felt that Naoko did a very good review. One thing I liked was how she went in depth with thing like the Deccan Traps, providing good analysis instead of a quick answer. A second thing I liked was how she provided information on other theories on how the dinosaurs were wiped out, like volcanos or an astroid. A final thing I liked was how Naoko check her review and made sure there were no spelling or capitalization mistakes. One thing I thought she could improve was adding dialogue from the article to give her review more credibility. To fix this, all she and to do was to add in a quote or 2. A second thing I felt she could improve upon was adding in some of her own ideas, as she seems to just be restating facts the author gave. To fix this, all she would have to do is provide her own ideas about some of the thing she discussed. One thing that really stuck out to me is that there is still no solid evidence to really prove what wiped out the dinosaur for sure.

  5. As a dinosaur nut, this article was not very new to me. First off, it has been known for quite some time in the paleontological community that the Deccan Traps erupted right alongside the meteor impact. However, she did not state several of the many other factors contributing to the dinosaur extinction, as well as skipping over how volcanos activity affected the dinosaurs: First, the meteor's initial landing generated a blast over a billion times stronger than the bombings of Hiroshima and Nagasaki combined, setting off massive earthquakes and tsunamis. These seismic disturbances may have also triggered the volcanic eruptions. The next feature is the sky itself. The amount of dirt thrown up by the meteor, combined with the massive amounts of volcanic ash being produced, completely blocked out the sun itself! This would have annihilated the plant life of the time, leaving the herbivores with nothing to eat, in turn causing the carnivores to starve. Some of the sediment was launched into the thermosphere, where the intense heat caused the silica in the soil to melt. When it fell back towards earth, the molten silica hardened and fell to earth as a storm of glass shards! The amounts of sediments and soil leaking into the water caused large amounts of acid rain to pelt the landscape. As the soil fell, a massive pulse of radioactivity seared the landscape, killing even more creatures. The heat generated from this would also cause massive fires worldwide, further destroying food sources for animals. With all of this, it's frankly mid-boggling to realize that some animals actually survived the extinction!
    Overall, Naoko had a good idea, but this report could have been vastly improved if she had taken the time to explain the dinosaur extinction, as well as the entire article, in more detail.
