New estimates suggest the mammals’ feeding habits help take in carbon
Web edition : Saturday, October 17th, 2009
In this article I have learned about how sperm whales are actually helping reduce carbon emissions, contradicting the old theory of how they made them worse. Sperm whales help reduce carbon emissions by pumping up iron into water that’s closer to the surface, they do this when they eat because after the whale has dived down into deeper waters to get its food it brings back a lot of stuff by the time it gets to the surface, some of the stuff is iron. This is good because it means that in areas where there is hardly any plankton the iron can feed the plankton that exists which contains carbon and even when the plankton dies the carbon remains in the water like a “carbon sink”.
This article is very interesting because our earth is going through a climate change, and carbon emissions are a huge part of the greenhouse gasses creating the hole in our ozone. So by knowing that Sperm Whales are actually helping reduce carbon emissions rather than produce them is an important fact when studying about the climate change. One thing this article could have done a better job at is making the article a bit more reader friendly; using more words that are easy to understand, and explaining exactly why the Sperm Whales were not big carbon producers rather than giving a bunch of points but never really saying it all together.
I think this article is very interesting because it is nice to know that naturally animals help fix our world by their daily eating habbits. I also think this is a great article because that means our ecosystem is going to slowly progress but we also need to help. Last the only thing i think this article could have done better was explain how our ecosystem is getting better
ReplyDelete3: Choice of article interesting
ReplyDeleteReview understandable
Review short enough to hold my attention
2: Could explain a little more
And some other second thing
1: I didn't realize that sperm whales were of
any imporance (other than humour)
I thought this article well written overall. Georgia was able to reach out and connect with people very well by talking about what people are thinking about. Also, there wasn't any complicated language in the review, which makes it easier to read. Finally, I found this review to be very interesting and it makes you want to read it. However, I would have liked to have known whether carbon would hurt the ecosystems in the ocean where sperm whales live. Also, i want to know whether plankton contain a lot of carbon or not. I learned from this article that humans aren't the only animals trying to stop global warming.
