WARM UP #14: Human Population Growth / AgBiotech
With selected student responses
QUESTION 1: Even if the world were
to achieve ZPG (zero population growth) today, the human
population will continue to grow (not level off) for more
than 60 years. Why?
From Ang: Q1 = Because of all the young
people around today who will one day reach reproductive age.
From AS: Q1 = IF the world achieved ZPG
today the human population would continue to grow for more
than 60 years because of the youth of the population. Since
the youth can not reproduce yet we have to expect that when
they are old enough to reproduce they will.
QUESTION 2: If you were
eating genetically modified (GM) food, would you know it from
reading a food label? Or do you think you are already eating
genetically modified foods right now? How do you think
genetically modified food is regulated and tested for
saftey?? Please read the notes before answering this
From Jennay Q2 = I don't
think that they always tell you if your food has been
genetically altered. I know that we are already eating
genetically altered food such as corn. They better be testing
modified food for safety!!!
From LT: Q2 = I don't think
you can tell what foods are genetically modified by just
reading the label. I don't think the companies want you to
know that. Yes, I do think we are already eating (GM) food.
Until I read the notes I didn't know baby food and formula
was (GM). It is tested by USDA, EPA,although the FDA
does not require the food to be tested they do want them to
consult with them before it goes on the market.
From SP: Q2 = If you were
eating GM food you wouldn't necessarily know it because labeling
is voluntary. I know that I'm eating GM food now
after reading the notes (Morning Star products)! The EPA
tests the crops to make sure they are fit for human
From DH Q2 = I don't think
you would know if you are eating GM food. I've never seen
that particular code on any product label or a label on
produce. I think we are already and have been eating GM
foods for a very long time. I think it is tested by the USDA.
Also the EPA and FDA can also be a part of testing for
QUESTION 3: If world
production of food were to increase such that there was more
than enough food for all the people on the planet, why would
40,000 people still die of starvation every day? Please read
the notes before answering this question!
From AA: Q3 = 40,000 people would still die
of starvation each day because economics, politics,war,
and poverty are still going to be around. Lack of food
being the main reason for world hunger is just a part of
the story. The things mentioned above a big reason for the
problem also.problem of some people can't afford to buy the
food the need to survive.
From JS: Q3 = The reason for people still
starving to death is because of politics, war, money, and
much more. The bottom line is that if the people do not
have the money or access to the food they will die.That
From Ash: Q3 = World hunger isn't caused by
scarcity of food. It is caused by limited access to food, or
not having enough money to buy food.
From RV: Q3 = The production of food is
only part of the starvation problems that we have in the
world today. It is not just a matter of producing food. If
you have the money to by the food great, if not then you
starve. But it is also a matter of politics, lack of
nutritional knowledge, medical treatment, clean water, sewage
treatment and other things that contribute to the starvation
of the world. So many other factors play a part rather than
just food. If it were just food, the answer would be simple
but there are countries that can't afford to buy the food
they can't grow. These countries may not be able to grow food
because of the climate and environment of the place they
live. They may not be able to buy the seeds needed to grow
the crops for eating. Starvation is SO MUCH MORE
COMPLICATED that just simply having enough food.
From Dr. Marrs: Thanks for
all your thoughtful comments on this issue. Sadly, we already
produce more than
enough food for all the people on the planet, yet 40,000
people around the world die DAILY from starvation and the
effects of malnutrition (some estimates even go as high as
100,000 people per day...). Parts of the world fare worse
that others - today in Sudan, millions of people are facing (or
dying from) the multiple hardships of poverty, starvation,
drought, and the longest uninterrupted civil war in
If you are feeling bad
about all this (and it is hard not to feel bad about it!),
remember that you CAN make a difference - get involved by
staying current in world events by reading your favorite
magazine, newspaper, etc, or by making donations of your time
or money (depending on which you have more of!!!) to
organizations in Indianapolis (like the Wheeler Mission), the US or the world (Oxfam
that are involved in alleviating the root causes of poverty.
Even making a temporary donation (holiday food drives, serving in the Wheeler Mission Soup
Kitchen, etc) WILL
make a difference to the people who had a good meal that
day thanks to you!!!
