The document discusses the lithosphere and plate tectonics. It can be summarized as:
1) The lithosphere consists of three main zones - the core, mantle, and crust. The crust is the outermost and thinnest portion, made up of continental and oceanic crust.
2) The continents are not fixed but rather drift atop tectonic plates that move across Earth's surface, causing geological events like earthquakes. For example, the San Andreas Fault marks the boundary between the North American and Pacific plates in California.
3) Plate tectonics have influenced macroevolution over hundreds of millions of years. The breakup of supercontinents like Pangaea caused geographic
REDD policymaking in Nepal: business as usual or transformational change?CIFOR-ICRAF
Nepal is recognised for its participatory conservation and community-based forest governance policies and programs. But in recent years, government officials and forestry bureaucrats have attempted to restrict the autonomy of forest communities and capture more economic value from forests. This presentation examines whether the current process of REDD policy formation – and the actors involved – will reinforce existing centralised forest governance, or forge more cooperative institutions capable of producing effective, cost-efficient and equitable outcomes for REDD.
Bryan Bushley, of the University of Hawaii and East-West Center, gave this presentation on 18 June 2012 at a panel discussion organised by CIFOR and partners at the ISEE 2012 Conference at Rio, which convened under the topic "Ecological Economics and Rio+20: Challenges and Contributions for a Green Economy". The panel was titled ‘National strategies for reducing emissions from avoided deforestation and degradation – how much transformational change is possible in current political and economic realities? Part II – A policy network perspective’. The research forming the basis of this presentation was conducted collaboratively with Dil Bahadur Khatri and others at ForestAction Nepal.

Carbon is an essential element for all life forms on Earth. Whether these life forms
take in carbon to help manufacture food or release carbon as part of respiration, the
intake and output of carbon is a component of all plant and animal life.
The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced,
meaning that the amount of carbon naturally released from reservoirs is equal to the
amount that is naturally absorbed by reservoirs. Maintaining this carbon balance
allows the planet to remain hospitable for life. Scientists believe that humans have
upset this balance by burning fossil fuels, which has added more carbon to
the atmosphere than usual and led to climate change and global warming.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

lithosphere lecture
1. Earth’s Lithosphere
“In the developed world. . We no longer honor
our relationship to the soil. . . Soil has simply
become one more resource - a substance
necessary for crop production and for holding
up buildings. . . “
(Elena Wilken. . . World Watch article, 1995)
2. Let’s start with the Lithosphere
3 major zones of Earth:
Core - very hot, solid & liquid
Mantle - solid zone, largest (68% of its mass,
rich in iron, silicon, oxygen & Magnesium
Crust - outermost & thinnest portion, consists
of continental crust (29%) & oceanic crust
(covers 71% of Earth’s surface)
3.

5. Plate Tectonics and Macroevolution
– The continents are not locked in
place.
• They drift about Earth’s
surface on plates of crust
floating on a flexible layer
called the mantle.
– California’s infamous San
Andreas fault
• Is at a border where two plates
slide past each other.
7. About 250 million
years ago
• Plate movements
formed the
supercontinent
Pangaea.
• Many extinctions
occurred, allowing
survivors to diversify.
8. About 180 million
years ago
• Pangaea began to
break up, causing
geographic isolation
& new species
9. Tectonic Movement is A Natural
Part of Planet, but Can we predict
earthquakes?

10. Earth’s Lithosphere
Crust contains
8 elements make up 98.5% of weight of Earth’s
crust (O, Si, Al, Fe, Ca, Na, K, Mg)
–Minerals (any naturally occurring inorganic
substance found in Earth’s crust as a crystalline
solid)
–Nonrenewable fossil fuels
–Potentially renewable soil nutrients (eroded rock,
mineral nutrients, decaying organic matter, water, air
& living organisms)
11. Earth’s “continental crust”
Earth’s land surface:
–Only 11% arable (useable
for agriculture)
•Rest too nutrient poor, cold,
wet, dry, etc.
–Possible to add 24% more to
arable land category if we
irrigate & use fertilizers
–Total to possibly 35% of
land surface potentially arable
12. Element = Carbon
Carbon is essentialessential to life as we
know it
Carbon is the basic buildingbasic building
blockblock for all organic compounds
necessary for life (carbohydrates,
proteins, fats, DNA)
To study life is to study Carbon
Chemistry!
13. Organic Compounds
Compounds which contain :
– C (Carbon) combined with :
– H (Hydrogen
– O (Oxygen)
– N (Nitrogen)
– S (Sulfur)
– P (Phosphorus)
– Cl (Chlorine)
– F (Fluorine)
All other compounds are called inorganic
compounds
14. Carbon CycleCarbon Cycle
It involves naturalnatural processes
A global gaseous cycle
(atmospheric cycle in which a large
portion of a given element (C)
exists in gaseous form (C02) in
atmosphere
Nutrients (like Carbon) are recycledrecycled in various
chemical forms (cyclic movement of carbon in
different chemical forms)
C cyclescycles from the abioticabiotic environment to the livingliving
organisms and back to the abioticabiotic environment
16. CARBON DIOXIDECARBON DIOXIDE
C02 Cycles fairly rapidly from the atmosphere,
through soil and organisms, and back to
atmosphere
Key component of nature’s thermostat
If too much C02 removed from atmosphere, the
atmosphere will cool
If cycle generates too much C02, the atmosphere
will get warmer
So C02 does affect the BIOSPHEREBIOSPHERE ( and can
determine temperature & possibly changetemperature & possibly change
climateclimate)
17. Some CO2 is utilized to produce
biomassbiomass in trees and plants
Which can form fossil fuelsfossil fuels after
millions of years of decomposition
and compaction (as buried organic
material)
When fossil fuels (coal, oil,gas) go
through combustioncombustion (burning
process), CO2 is released back
into the atmosphere
18. Terrestrial producersproducers (green plants and trees)
remove CO2 from the air
PHOTOSYNTHESIPHOTOSYNTHESIS takes place 6CO2 +
6H2O + solar energy is converted into
C6H12O6 (glucose)+ 6O2 (oxygen)
ConsumersConsumers and decomposersdecomposers breakdown
glucose (consumption) and utilize oxygen for
respiration
The Hydrocarbons get converted back to CO2back to CO2
in the atmosphere
19. Humans and causes of increases
in CO2 (all unsustainable practices):
Cut down treestrees (producers of oxygen
and users of CO2)
Industries
Transportation (i.e.,cars)
Buildings
20. Increased amounts of carbon:
Global warming (rising sea/water level)
May lead to extinction of certain plants,
insect and animals, which could cause an
imbalance in the food chain.
Acidification on oceans
