Homework: Answer these three questions thoughtfully and carefully and, of course, in correct English
(1) How do I personally contribute to climate change? (examine your lifestyle — from your diet to your consumption to your home). Note: To answer this question, you should examine your ‘footprint.’ What is an ecological footprint. As explained by the Happy Planet Index, “[t]he ecological footprint of an individual is a measure of the amount of land required to provide for all their resource requirements plus the amount of vegetated land required to sequester (absorb) all their CO2 emissions and the CO2 emissions embodied in the products they consume. This figure is expressed in units of ‘global hectares’. The advantage of this approach is that it is possible to estimate the total amount of productive hectares available on the planet. Dividing this by the world’s total population, we can calculate a global per capita figure on the basis that everyone is entitled to the same amount of the planet’s natural resources.”
So, to answer question (1), go to one The Global Footprint Network website (http://www.footprintnetwork.org/en/index.php/GFN/), and read the information they have, and then you can go to one of the following sites: The Ecological Footprint Quiz (here), or The Global Footprint Network (and assume we live in Turkey), or go to the website of the World Wildlife Fund and spend 5 minutes calculating the information (here) – but keep in mind that that calculation is designed for folks living in the UK so some of the questions won’t apply to you. There are other sites, of course. The links I provided are a selection of those sites. One other avenue you may use is an excel sheet to calculate your footprint with more accuracy and detail. Go here: http://www.google.com/search?client=safari&rls=en&q=ecological+footprint+xls&ie=UTF-8&oe=UTF-8
(2) What will I actually change in my behavior?
(3) Assuming I have ultimate power in the world, what new world would I create? What is my vision for a healthier world — healthier from an environmental perspective, recognizing that the environment cannot be separated from the economy and from our philosophies.
Deadline: PDHP class: 2nd of May. BIOL class: 5th of May

ONE hot summer, the lake in which two Frogs lived was
completely dried up, and they were obliged to set off in
search of water elsewhere. Coming to a deep and
deliciously cool well, one of the Frogs proposed that they
should jump in at once. “Wait a bit,” cried the other;
“if that should dry up, how could we get out again?”
what do you understand from that??

thank you Majed for this great story. I’m not sure i got it right, but i understood from it that we are not the only creatures that can think! maybe thinking here is a kind of metaphor for adaptation where the frog could learn from a previous experience and was able to predict the future basing on the past and on the concept that the future will resemble the past.

Don’t you think that writing 3 essays at a time is too much for an ecology course as a part of our major biology courses! i’m starting to feel that i am taking an ECO-english course! 😦
By: Mireille Jabroun (BIOL 207) on April 19, 2010
at 5:39 pm
Dear Mireille,
The first two questions are not essays. And since you want to discuss how this class is relevant to our life, then the questions become all the more relevant.
And, since biology students at UOB do not take enough writing, then a bit of extra writing becomes necessary.
Lastly, the idea of these homework assignments is to provide different means of evaluation (i.e. your grade) so that the grade of the class is not fully dependent on exams. Since the exam grades are not that great, this option should be good news to you all.
Cheers
-Rania

i agree with Mireille, it is enough that we had to go through at least 2 english courses, i do not think that we should suffer more with english in a science course…It is also important to note that english is not our native language and for most of us not even our second language and therefore we do not really have to master it as if we were americans or british or something.I think that most of us have reached a good level in english with respect to our situations…
By: Anonymous on April 20, 2010

i totally agree with the both coments, i think that we should focus more on the ecological part than the language. After all we have already done a full summary for an artical and a homework. i feel like i’m back to ENGL 201
By: Anonymous on April 20, 2010

Honestly, in all my four years of teaching Ecology, I have yet to meet a class that complains this much.
Suffer with more English?
I am asking you all to consider your own lives, to apply what we are learning to your own lives, and to envision a better world. To do so, yes, you will have to write it in English since the teaching language at the UOB is in English.
Truly, I am constantly surprised how much students want to be cheated out of their own education.

Dear Anonymous
English literature?
What English literature am I asking you to read, or to write about? Literature?
I ask you to think. To critically examine your lives. And you speak of literature? Either you are grossly overestimating your writing skills and comparing a response to three questions as “literature” – or you are proving that you do need to focus more on thinking and writing and that this exercise is relevant.

Dear Dr. Rania
I totally respect the way you are giving your course and the level of devotion toward it, and I believe that you aim to “teach us” and not to” give us a grade.” I would prefer that most biology courses (genetic, cell, biochemistry, molecular biology, nutrition and animal physiology) should do the same, since they catch my interest.
Ecology and I have lots of chemistry, in the same way that nitroglycerine and peroxide do!
No offence intended but really ecology is a “BULKY” course that minimally interests me.
And in the same way that you are adsorbed to ecology, I’m adsorbed to other courses too.
If I had the ability to clone your teaching strategies I would clone in into the courses that interest me the most! Because I know that no other professor at UOB is putting so much effort in the task he is doing as you do!( As searching for articles on the internet, correcting homework, and pushing us to think “outside the box”……..)
As for the English part:
A 3 month course won’t be efficient to teach us “a healthy grammar.” This job should have been accomplished by the English department instead of being a covered way for UOB to “snatch” some money. The English department is no more than a “pain in the ass.” In addition these weak educational systems of high schools are another cause of our weak language. However remember that we are taught 3 languages in Lebanese schools, compared to 1 or 2 in foreign schools, and our native language is Arabic, therefore we do not speak it a lot in public. Our expression in English is a translation of thoughts in Arabic!
Ma 3am Bayyid wijj, This is really what I think!

Guys honestly i feel like dealing with children; i don’t know how most of you are planning to get into med school with this mentality. It doesn’t make any sense the way you’re complaining. What english course is it? i mean you can’t write a good english paragraph about a human or social issue. We are scientists! but we’r humans first.If you really know some english like you are saying, you would notice that EXTRA credit means that you don’t have to do it if you don’t want to. So simply don’t do it. Don’t write essays or answer questions because it’s really annoying the way you are dealing with it; honestly i don’t wanna take the rest of the course with a pissed Dr because of students even complaining from EXTRA credits. So don’t do the homework and let us enjoy the rest of the course!

Please do not generalize about the med acceptance, I got a good grade on the MCAT (don’t tell anyone I had the MCAT previous!), instead of “whitening teeth” and wasting time on comments go study for you freaking tests instead of waiting for previous.

comment on: Boycotting bluefin isn’t enough—time to turn on the siren.
It is very strange how Japan blocked the proposal of CITES to list the bluefin tuna. It is not but a way to protect this species from extinction. Even though Japan’s economy relies on this fishery, extinction of this species will eventually cut the supply of this not only to Japan, Economy itself as a world means “management of the resources”. Therefore, if Japan would keep opposing the listing of bluefin tuna as an endangered species, it would not protect its economy, rather it is destroying it, since eventually, if no action was taken, bluefin tuna will be extinct. Therefore, this is not a reasonable management; it is only the tendency to get easy money without any planes for the future.

Comment on: Mammoth Dust Storm Sweeps China
The problem in china is that they have a huge population size, with huge economical demands. I think that their strategy is to overexploit all the possible resource now, and hoping for a technological fix in the future. Personally, I don’t think they have an alternative strategy. Of course they are aware of the danger of their behavior but, how are they going to feed all this number of people if they do not do so? How are they going to economically compete with the other countries? Of course, if we want to see a projection in the future, we can expect a huge desertification of the land, with massive soil erosions and drought problem. There are some precaution that could be taken that can dampen this effect… the number of cattle could be easily reduced if the food regime of the Chinese population got back to normal, slightly dependent on meat.

Comment on: Industrial ag once again demanding free pass to crap in your backyard
All companies are aiming to heighten their economical interest. They are willing to do anything just to get more money. It is not that weird to see companies embracing such a mentality. But what is not acceptable is the legislation of the bad actions of these powerful companies by the controlling agencies that were supposed to “control” such behaviors. It is the absence of control that is transforming our ecosystem to an unsustainable ecosystem. Thus, we should put the sustainability of our ecosystem as our first priority, otherwise, the ecosystem will collapse much sooner than we expected. Today, personal interest of some powerful companies is still having the first priority, which is causing all these problems to our world (nature and humans too).

Comment on: Molecular Evidence Supports Key Tenet Of Darwin’s Evolution Theory
The theory of evolution is a very controversial theory since some people cannot accept the idea that complex organisms can be derived from very simple forms. It is not only that they cannot accept this theory; they also cannot imagine the process, so they simply deny it. And of course there is a religious opposition of the evolution theory. But more and more evidence are beginning to appear to support that theory, and one of them is the TIM complex evidence that promotes the endosymbiosis theory.

Comment on: Zoologger: Colourful ducks may have fewer sex diseases
I did not really know how much the duck is sexually active. I once had a male and a female duck but I was not aware of their behavior maybe because I only had one couple. It is also amazing how the female duck can select the more profitable male to breed with… I didn’t know that they have that level of selection

WHY do frogs sing?
check their singing: http://www.youtube.com/watch?v=BOyaVEGM2yw
i found some answers online (more detailed than those in the book)
Spring Peepers: – females are voiceless
– males have 3 kinds of calls:
1- “Peeping” to attract females during breeding season
(Feb – May). they might call in duets, trios or quartets.
And the female selects a mate.
2- “Trill” to warn other males to keep their distance
3- “Release Call” that identifies them as males
