The
reduction in fish populations in the world has many causes, mostly climate
change. Ocean acidification and temperature
rises all reduce the available habitat for many species, especially those who
sit on the bottom of the food web. If
the lowest end of the food chain becomes endangered, so do everything else
above it. Considering that plankton count
has decreased phenomenally over the past decade, it is expected that everything
else as well will follow. Fishes are
also vulnerable to fishing. With very
little international effort to protect the fishing industry, many species are
becoming extinct or endangered. In order
to solve the problem of the ocean’s fishes, many preventative measures must be
taken. A good start is to reduce fishing
or start using fisheries to meet the demand.
Overfishing can easily change population dynamics and can also alter the
entire ecosystem of an ocean habitat. In
order to keep the oceans productive, measures must be taken to reduce carbon
emissions in the atmosphere. Organisms
at the bottom of the food chain are very sensitive to pH and temperature, and
in order to prevent these species from deteriorating, measures must be taken to
reduce climate change.
Adding graphics and sources to your information would make this information a lot more credible and add more validity to your argument.
ReplyDeleteI agree with Rebecca that both graphics and primary documents would help to bolster your argument greatly. You have a great start but once you narrow your focus, provide some concrete examples of the the conjectures you make, and revise the layout of your site I think it will carry much more credibility to the average reader. And don't be afraid to add some pictures to break up the big sections of text!
ReplyDeleteYou have a great start and bring up really important points, however I feel that some information is missing. Your explanation of OA was good and you made good points. If you provided some examples it would help strengthen your ideas. It was a bit hard to understand the main points of increasing temperature. By adding more explanation on how temperature is increasing and affecting currents and stratification it would help clarify. Again include more examples. Graphics should help strengthen your blog.
ReplyDeleteI agree, you need some pictures and a narrower focus. Try to relate each page to both climate change and fish. Also, you need to include your works cited. I feel that having your works cited page will make your blog seem much more credible. Good start though, there is a lot of good information here.

ReplyDeleteLike everyone else has said, focus and images. Images will often times naturally help focus your ideas because you have to figure out what exactly you need pictures of! They help direct the readers attention and really shape the flow of the blog.
ReplyDeleteYou have touched on just about every topic we have learned concerning the oceans here, so you need to narrow in on one of them. I would suggest breaking your posts up into tabs to help organize your thoughts. "Fish" is a very broad topic, as has already been said, so narrow it down to a single family or species. From there, you can take two approaches, either from the perspective of climate changing, or from the perspective of species changes. Right now you are doing both and it is hard to follow.
ReplyDeleteAs for the content, I would make sure to double check your sources. Assertions like "plankton count has decreased phenomenally over the past decade" are a little misleading when taken out of context. Try to avoid broad statements without qualifying them first, and stick to specifics, and your blog will be great.
