Here is how a canary looks and sounds like

Canary 1 Colony Collapse Disorder
  • We begin with bees, for they provide a natural
    link between the subject weve just
    coveredgenetic engineering, and our new
    subjectFrankensteins Monsters

4
Bees are an aesthetic and natural wonder
  • Queen, female workers, drone
  • Dance language
  • Altruismone dies for all
  • Thermoregulation
  • Fascinating behaviors, e.g., removal of dead bees
    from hives
  • Many other unsolved mysteries

5
Bees are also ecologically important Honey,
pollination
6
Bees, nowadays, are in the news!
  • e.g., an article in the Palm Beach Post, Monday,
    March 24, 2008
  • In the following slide we see a commercial
    beekeeper at work

7
Using smoke to calm his bees, Dave Hackenberg,
examines a beehive March 30, 1999 near Dade City,
Fla. He has about 2,600 of the boxy beehives, and
his bees produce thousands of pounds of honey and
pollinate tens of thousands of acres of
blueberries, pumpkins, oranges, apples, and
clover.
8
seemingly healthy adult worker bees suddenly
abandon their hives, never to return
  • A 2008 survey suggests 37 percent of a sample of
    230,500 from ten US states have been lost

9
Causes of Colony Collapse Disorder (CCD)
  • Several roadblocks to unraveling this mystery
  • Powerful interests cover up their involvement?
    Pesticide, insecticide, GMO profiteers?
  • Problem is complex
  • Human beings are not very good in long-term
    planning

10
Some possibilities
Varroa mites? These mites infest a colony,
eclose, attach themselves to an adult bee, and
suck her internal liquids, thus wounding and
weakening her.
  • varroa mites
  • These mites infest a colony, attach to the
    larvae, and suck the life out of them

11
The varroa explanation is favored by money
changers, but
  • Varroa mites are not new How did they become so
    mighty?
  • Organically-grown bees do not get CCD
  • The problem could be intestinal, and mites do not
    affect internal organs

12
Toxic Overload
  • Heavy reliance on pesticides and herbicides could
    poison bees, just like it poisons us?
  • Supporting evidence Organically-grown bees do
    not have CCD

13
cell phones may adversely affect the navigational
abilities of bees?
  • It would be pretty simple to rule this
    explanation out (but if this is the case, would
    you give up your cell phone?)

14
Genetically Modified Organisms?
  • Arguments for
  • Organically-grown bees do not die
  • In some cases, e.g., Frankenstein Corn, the corn
    is engineered to produce an INSECT TOXIN. The
    plants are built to kill insectsand they
    succeed. The Sierra Club feels that this
    explanation deserves considerable attention.

15
But by now you know the rules
  • Our politicians do not work for us, but for
    Monsanto, Dow Chemical, other corporations. So,
    our bees might well be on their last leg (wing?)
  • But doesnt the head of Monsanto like honey too?
    And almonds? And blueberries? I dont know the
    answer to this question except the suspicion that
    they are morons.

16
Immediate Practical Applications
  • There is one practical conclusion to all this,
    which is also a moral imperative
  • Whenever you can, eat
  • ORGANICALLY GROWN FOOD
  • And, Dont drink THEIR water!

17
Canary 2 Bats Perish, and No One Knows
Why New York Times, March 25, 2008
18
  • A description of an abandoned mine in New York
    State, where bats hibernate. Many are flying out
    and die, even though, in the words of one
    researcher
  • Bats dont fly in the daytime, and bats dont
    fly in the winter

19
  • In one NY cave,
  • 2006 1,329 bats
  • This winter 38 bats

20
Bats
  • fascinating (e.g., first discovery of
    echolocation)
  • pollinate crops
  • consume harmful insects
  • Paraphrasing Hopkins
  • What would the world be, once bereft
  • of bees and of bats?

21
Lets visit canary 3
  • This part of the lecture is based on the
    following required reading
  • Jared Diamond (1995). Adaptive Failure Easters
    End

22
The Environmental History of Easter Island
  • http//youtube.com/watch?vlmZqW_xh_eA (230-700)

23
Easter Island
  • 64 square miles, far away from everything
  • Belongs to the country of Chile, but its 2,000
    miles away
  • Mild climate, excellent soil
  • Inhabited originally by a mixture of Polynesians
    (as in Hawaii) and Europeans
  • So, all the ingredients of a paradise, no?

24
A Surprisingly Impoverished Island
  • First brought to worlds attention by the Dutch
    explorer Jacob Roggeveen, on Easter of 1722.
  • Appeared to him barren, only small trees
  • Only native animals insects
  • Domestic animals Only chickens

25
  • Only 2,000 people in the 18th century (now 4,000)
  • Lousy canoessurprising for the sea-faring
    Polynesians!

26
Huge stone Statues up to 65 feet and 250 tons!
On huge platforms
27
  • Statues were pulled down in the 19th century, by
    the islanders themselves?
  • How did they build and transport the statues,
    without big trees, rope materials, draft animals?
    Did extraterrestrials built the statues?

28
Science to the Rescue
  • Linguists can estimate how long they have been
    separated from other Polynesianssince about 400
    AD.
  • Archeologists, carbon dating, again, same
    approximate date
  • Population once 7,000-20,000 people
  • Statues built up to year 1,500

29
Pollen analysis
  • Can dig the earth, examine for pollen as you go
    down, look at it under the microscope
  • When people first came, in about 400 AD, the
    island was forested with huge trees that could be
    used for food, ropes, firewood, canoes, rolling
    the statues

30
  • Excavations show that the islanders captured
    dolphins at sea with sturdy canoes, and feasted
    on a variety of local birds (all gone by first
    contact with Europeans)
  • So they did come to a paradise? How did it
    become a wasteland?

31
Population grew, so
  • By about 1,500 AD Extinction of almost all
  • shellfish
  • birds
  • trees
  • sono more good canoes, no more dolphins to eat
  • No treesless streams and springs, more soil
    erosion

32
  • Starvation and cannibalism set in
  • Warfare became the norm
  • Population crashed to less than a ¼ of former
    levels
  • Statues were destroyed

33
Diamond asks What were they thinking when they
cut down the last palm tree?
  • Not so hard for us, who know about the demise of
    bees (and also bats, and birds in our backyards,
    and passenger pigeons, and bison, and . . . ) to
    answer this question, for we are repeating the
    Islanders mistakesnow on a biospheric scale!

34
  • Diamond believes the process was too slow for
    anyone to notice, and also, that there was the
    opposition of vested intereststhe loggers, the
    priests, etc.

35
Diamond Easter Island is Earth writ small
  • Diamond does not give up in despair, because
  • My main hope for my sons generation is that we
    may now choose to learn from the fates of
    societies like Easters
  • Do you share Diamonds cautious optimism?

36
Canary 4 Overpopulation and Rapid Population
Growth
  • Would the Easter Islanders run into problems had
    they passed a two-child per family law, or
    decided to limit the islands population to
    1,000?

37
The answer is NO. With a few people on a big,
fertile, forested island, they would have indeed
been living in a sustainable paradise!

Consider this chess board
39
An Ancient Iranian Tale
  • A king once wished to reward one of his subjects,
    agreeing to reward any reasonable request. The
    man wanted 1 grain of rice for the first square
    of a chess board, 2 grains for the second, 4 for
    the 3rd, and thus doubling all the way to the
    64th square. The king thought this was
    reasonable, and agreed. What would you do, if you
    were king?

40
  • It starts small enough 1, 2, 4, 8, 16, 32, 64,
    128, 256, 512, 1024, 2048, 4096, 8192, 16384,
    32768, 65536, 131072, 262144, 524288, 1048576

41
Exponential Growth
  • But at a certain point, things start to get ugly
  • 20 squares yield about a million grains,
  • 30 squares yield a billion,
  • 40 squares a trillion,
  • 50 squares a thousand trillion,
  • 60 squares a million trillion

42
Its totally unlike adding FIXED amounts
  • 10005
  • 10055
  • 10105
  • This is a slow process, posing little problems.
    It will take 200 steps to just double.

43
  • Rather in the chess case, we add percentage.
    Lets examine another puzzle
  • I place a single bacterium in a dish right now,
    11 a.m., Wed., April 2, 2008. It splits into 2
    in 20 minutes, into 4 bacteria in the next 20
    minutes . . . Lets say the dish can only hold 1
    million bacteria, and that this point will be
    reach by 6 p.m. today. At what time will the
    dish be half-full?

Answer 640 Moral Crisis, when it comes, comes
fast!
44
This raises a question about earth Are we
repeating the Easter Islanders mistake?
  • The answer here is clearer than it was in their
    case. Scientists have been hollering from
    rooftops about this, but no one listens. It
    takes just one graph to capture the human
    predicament!
  • Relevant information EB, pp. 393-6

45
The History of Global Population Growth
  • Human population Has been growing almost
    exponentially for centuries.
  • Please examine the next frightening graph

46
Figure 18.24
47
Figure 18.25
48
  • Another way of putting it By 12/31/08 there
    will be 70,000,000 more people on earth than
    there were in 12/31/07!!!
  • Increases in the human population result in more
    people consuming resources and dumping pollutants
    into the biosphere.

  • There is a wonderful book called Lies My Teacher
    Told Me. Here is one example of why most of us
    are sleepwalkersa widely used textbook (yours!)
    has only this to say about this catastrophe, this
    cataclysm, of exploding human populations
  • A unique feature of human population growth is
    that we can control it with voluntary
    contraception and government-sponsored family
    planning. Leaders in almost every country
    disagree as to how much support should be
    provided for family planning.

51
  • One thing we can surely agree on is that
    textbooks, like schools and the media in general,
    are not passionately committed to the truth.
  • The truth is Were walking in the footsteps of
    the Easter Islanders! The truth is because more
    people mean more power for popes, and rabbis, and
    presidents, these leaders actively promote
    population growth. They care not for the
    biospheres future!

52
These popes, imams, rabbis, and Congressmen do
not want you to know this
  • Warning issued on November 18, 1992
  • World Scientists' Warning To Humanity

53
  • Human beings and the natural world are on a
    collision course. . . . Fundamental changes are
    urgent if we are to avoid the collision our
    present course will bring about
  • Questions Have there been any fundamental
    changes?
  • Answer Of course there have
  • for the worse!

54
There are many, many more, canaries from whence
the above 4 came, e.g.,
  • Massive species extinctions (and dying frogs,
    bees, bats, birds)
  • Damaged ozone layer
  • Destruction of oceans, topsoils, lakes
  • Synthetic chemicals everywhere
  • Nuclear power and nuclear bombs

55
  • Growing space pollution
  • Space warfare
  • Increased global genocidal activities
  • Resource scarcity
  • Deforestation
  • Lower sperm counts and higher rates of cancer,
    asthma, autism . . .

56
Are we Sane?
  • Now, the entire point of having a canary in a
    coal mine is YOU BETTER WATCH OUT When the
    canary died the miners knew they had to GET OUT
    of the minefast.
  • Alas, we
  • Cant get out of our mine (Earth)
  • Pay no attention to the deaths of our canaries!

57
Canary 5 But in our next two lectures, well
limit ourselves to just one more tipping point
Climate Change
  • Our main source for this A lecture given by Al
    Gore, a former U.S. V.P., and the man who won the
    2000 Presidential elections in the U.S.
