Lab 3
1.
Why do you think Carson titles this
chapter “A Fable for Tomorrow?” Think about the choice of words in the title.
Think about what fable teaches us and apply that here. I
think that she chose this title as a warning for us. If we don’t change our ways
we are essentially killing not only ourselves but also the wildlife around us.
2.
What did you know about pesticides
before watching the Earth Days segment or reading part of Silent Spring? As a child I did not know anything about pesticides. Now
that I am older and have children of my own I worry about them getting sick
from the pesticides that are put in our food.
3.
What do you feel so strongly about
that you would want to fully dedicate yourself to it, producing a
groundbreaking work of literature, film, music or other media, even if this
risked your professional reputation and how others thought of you? Your answer
can be hypothetical! Not everyone has a passion that they would carry this far.
I was raised to be polite but to also do the right
thing no matter what. If I loved something enough I would do whatever it took
to get my message out there. Even if that meant not having any of my peers agreeing
with my point of view.
4.
Name four places pesticides exist. There pesticides located in the air we breath, the water
we drink, the food we eat, and the land we live on.
5.
What are two effects of DDT on birds
and mammals? DDT causes birds eggshells to thin can
kill them. On mammals DDT can kill small animals and on humans it can be toxic
and make us vomit, cause tumors among other things.
6.
“Our aim should be to guide natural
processes as cautiously as possible in the desired direction rather than to use
brute force...Life is a miracle beyond our comprehension, and we should
reverence it even when we have to struggle against it...Humbleness is in order;
there is no excuse for scientific conceit here.” – Rachel Carson in Silent
Spring.
Take a little time to define
humbleness in an appropriate manner for this question before answering.
How can we exhibit humbleness in
terms of our relationship to nature? To exhibit
humbleness with nature, we should consider that the earth is much more powerful
than us and it can and will destroy us if we continue mistreating it the way we
have been.

Labeled drawing of biological magnification example (3 points)
Biological magnification is the process
whereby certain substances such as pesticides or heavy metals travel from
organism to organism as they feed. The chemicals move into rivers or lakes and
are eaten by aquatic organisms such as bacteria, invertebrates, and fish, which
in turn are eaten by larger animals such as birds and other animals including
humans. The substances become concentrated in tissues and organs with each
step in the food chain or web.
Procedure
-The picture states that mosquitoes and other
pests were being killed because people were using DDT to get rid of them. Fish
eat these pests with the DDT in them. The eagles eat the fish and the DDT ends
up accumulating in the eagles. This affected eagle eggs, the DDT made them weak
and they became so thin that they would crack and no baby eagles would hatch.
Part 3
1.
Find the data for the state for
which you have an interest. Draw a line graph by hand or using Excel or another
digital program. Add your graph to your blog site. Be sure to label with the
name of the state. (3 points)
2.
Explain
a)
The overall trend of bald eagle
populations in your state during this time period. In
California from 1995-2005 the Bald Eagle population increased from 110 pairs of
mating eagles to 200 pairs of mating eagles.
b)
The average increase in population
for the state you chose. What percentage increase does this represent? From the time frame I chose the total increase was about
55%. This number represents the pairs of mates that the state has.
c)
Two programs that protect bald
eagles: The endangered species Act made sure that
the U.S. Fish and Wildlife Service and The National Marine Fisheries Service
invest time and resources into protecting endangered species.
Part 4
1.
Review concept of personal
ecological footprint. The ecological footprint is
the amount of a biologically productive area that is used to sustain resource
consumption of an individual.
2.
Predict how many Earth's each person
needs, if they all lived your lifestyle: If
everyone lived the way I did we would need 3.8 earths to support them all.
3.
Calculate your ecological footprint
using the, Earth Day Footprint Calculator (http://www.earthday.org/splash_page.php). Many other variables may come to mind as you
do your assessment, or the questions might not "fit" your
circumstance. Just do your best. It is probably best to ignore the donation
request. 3.8 earths.
4.
How do you feel about this? Comment
on your reaction in at least five sentences
I really felt that there
was a problem with the website. I try to eat very healthy and organic as much
as possible so needing 3.8 planets was a bit shocking. I feel like the electric
question is not fair, what if I have solar panels and only pay APS $12.00 a
month to store my energy? They should factor in more eco friendly options that
go into detail. After completing this quiz I think I have some things to
change in my life to help the planet.
