- An incredible moment in history utterly economic information that our dependency on
fossil fuels is killing the environment, trapping heat in a dangerous way
- Climate change so over whelming causes other people to change topic
- Oea’s plakto- 95% of heat trapped from fossil fuel is absorbed ocean, surface level
of ocean that is where plankton live, cant live below because they need sunlight
- Marine snow- fish poop forms basis of food chain at the bottom a lot of marine snow
brought up to the surface and serves as fertilizer for plankton
- Plankton makes up half of the oxygen we breath
- Ocean absorbs not just excessive heat also carbon dioxide turning into carbonic acid
oceans becoming acidic
- The entire food chain depends on zo plankton a massive species instinct is under a way
fossil fuel killing animal life on planet
- Also killing us, PCB like to preterm, birth, breast cancer
- Hydras responsible for dead zone in Gulf of Mexico
- Not part of our common understanding because we are not talking about them
- Another complex system ecological system in which our well being relies on
- One hand our economic depend on fossil fuel is suicidal, and we are on attempts to get
the remaining fossil fuels out
- They are extracting harder fuels at great risk
- Other path of extreme fossil fuel extraction
- Mountain top removal and destroy its ability to produce food, drill for oil in bottom of
oceans, pipeline from Alberta and shovel into the tar, fracking under the bed rock blows
it apart to get at the carbon trapped inside
- A lot carbon left in the ground, we need to make conscious decision as citizens are big
decision to allow or disallow the extraction of methane
- Fracking high volume slick water hydraulic fracturing water mixed with tons of
chemicals to shatter shale formation below our feet. Shale represents ocean floor in a
time when there was not a lot oxygen.
- Old way of extracting was sticking a straw was traditional gas drilling.
- Deep water extraction related to earthquakes, chemicals used to reduce friction cause
rocks to become slippery and cause earthquakes.
- Shale is an ecosystem- deep life new discovery
- The living part of earth biosphere goes way below earth as well
- Marcela shale not just a graveyard it is a living ecosystem something we need to bring to
public conversation
- Consequences of fracking for public health: cancer survivor, diagnosed with bladder
cancer, did I ever smell aluminum, grow up in industrialized place became apparent with
environmental cancer.
- Kind of cancer that is more likely to reoccur
- Living downstream best attempt understand environmental links to cancer became and
environmental detective.

- Science has really emerged to show high levels of cancer, better and better at
understanding different environmental signals can lead to tumor formation
- Drying cleaning fluids in drinking fluids in hometown plurochlorine ethane causes cancer
found in water
- Essentially an unfixable and human rights problem
- Chemicals in fracking:
- Eggs and sperm: women who smoke exposed to benso Eggs and sperm: women who
smoke exposed to benso a preyen can cause eggs to die and cause cancer and fertility is
lower. Same chemical found is diesel and gas. Fracking and womens fertility share
common factor. Actually can affect womens ability to become pregnant. Implantation
important phenomenon in pregnancy.
- Chemicals like air pollutants related to asthma, pre term birth,
- Gas drilling relies on carcinogens
Globalization, Climate Change, and Human Health
Global changes around the world are fundamentally influencing patterns of human
health, international health care and public health activities.
Increasingly systematic environmental impact of many economic activities urbanization
and widening gap between rich and poor countries

flow of information movement of people trading patterns the flow of capital and
cultural diffusion. This increase and demographic, economic and commercial and
environmental indexes have been labeled the great acceleration. Remarkably the
resultant and environmental effects are now altering major components of the earth
system.

the boundaries considered to be safe for continued human social and biological well-
being. The loss of biodiversity the greatly amplified global circulation of bioactive
nitrogen compounds and human induced climate change have already reached levels
that are apparently unsafe.
These changes post fundamental threats to human well-being and health. Fees human
induced climate changes often act in concert with environmental demographic and
social stressors that variously influence regional food yields nutrition and health.
Furthermore at the current level of global connectedness and interdependence the
environmental impact of human activity has wider Geographic range although its
influence maybe offset somewhat buy more effective global alerts and more rapid
distribution of food aid.
On the economic front the recent global financial crisis has underscored the domino
like interdependence of national economies.
