List of Topics to be covered : -
Parts of Environment: -
•Atmosphere –It is composed of several distinct layers
such as troposphere, stratosphere, mesosphere and
ionosphere.
•Hydrosphere –Water –Ocean
•Lithosphere –Solid part of the Earthcrust.
–The crust includes minerals, soil androck.
–Largest volume of Earth’s interior –Mantle.
•Biosphere–ItisthepartoftheearthwhichincludesAir,
Land,Water,Rockwithinwhichlifeoccurs.

Water Cycle
( Hydrological Cycle): -
How does the hydrosphere interact with the other spheres?
ATMOSPHERE: -
This is the thin, life-giving gaseous envelope of the
Earth. Its composition is divided into:
A.Major components (N,O)
N = 78.08%
O = 20.95%
Rest are Carbon di oxide and other inert gases.
B.Variable components (water vapour and aerosols)
WATER VAPOR is the gaseous phase of water able
to trap heat on.
An AEROSOL is a suspension of fine solid or liquid
particles in a gas (smoke, fog, mist).
GEOSPHERE :-
The solid region of the Earth which comprises not only
the solid visible layer but extends to the centre of the
earth.
Crust: -
• outermost layer of the Earth
• relatively thin (1% of the Earth’s volume)
• crust is thickest at mountainous regions
Geosphere Mantle : -
• 82% of the Earth’s volume
• upper and lower mantle
• rocky lithosphere (upper mantle)
Geosphere Continued…
Geosphere Core
• upper and lower core
• upper and lower core
• solid inner core
Geosphere is the Solid part of the Earth crust.
The crust includes minerals, soil and rock.
Largest volume of Earth’s interior –Mantle.
Ecology, Environment & Ecosystem :-
Ecology is the study of interactions between organisms and surroundings
occurring within an ecosystems or the environment.
Environment is a group of ecosystems.
Ecosystem → Producers, Consumers, Decomposers and their relationships
(tiny environment). It is the functional unit of the environment.
Ecosystem is a functional unit of environment (mostly biosphere).
Habitat → Area where an organism lives.
Environment → Can be Almost Everything or a Small region.
Components of Environment:
BIOTICcomponents
•The biotic components of an ecosystem can be
classified according to their mode of energy
acquisition.
•In this type of classification, thereare:
Autotrophs : Organisms that produce their own food from
an energy source, such as the sun, and inorganic
compounds.
Heterotrophs: Organisms that consume other organisms
as a food source.
Types of an Biodiversity: -
According to Whittaker (1965), the community
diversities are of three types:
(i) α-Diversity:
(ii) β-Diversity:
(iii) γ -Diversity:

Importance/ Values of
Biodiversity:
The living organisms on earth are of great diversity,
living in diverse habitats and possessing diverse
qualities and are vital to human existence providing
food, shelter, clothing’s, medicines etc.
The biodiversity has the following importance’s:
1. Productive values 2. Consumptive value
3. Social value 4. Aesthetic value
5. Legal values 6. Ethical value
7. Ecological value 8. Economic value
Values of Biodiversity :-
1.Productivevalues:

etc.
2.Consumptivevalue:

3. Social value:
The loss of biodiversity directly influences the
social life of the country possibly through
influencing ecosystem functions (energy flow and
biogeochemical cycle). This be easily understood
by observing detrimental effects of global
warming and acid rain which cause an
unfavorable alteration in logical processes.
7. Ethical value
Biodiversity must be seen in the light of holding
ethical value. Since man is the most intelligent
amongst the living organisms, it should be prime
responsibility and moral obligation of man to
preserve and conserve other organisms which
will directly or indirectly favour the existence of
the man.

• Introduction of improved method of cultivation based on science and
technology.
• Improvement of financial and educational status of the Indian cultivators.
• Attracting educated people to the profession of cultivation.
• Provision of water-pipes, electricity, insecticides, fertilizer and research work
for agriculture.
• Mechanization of agriculture. • Equitable land-reform.
• To refrain from holding feast and picnics in order to check the possible
wastage of food.
• To know the proper method of dressing and cooking in order to
check the wastage of food.
• To know the method of food preservation in order to save the perishable foods
from wastage.
• Provision of cold storage in every village and refrigerator in every household.
• Family-Planning through birth control.
How to solve the food problem of India:
Water Scarcity in India
• Renewable resource-but finite resource
• Only 3 per cent of the world’s water is freshroughly
one-third of it is inaccessible
• Simply put, water scarcity is either the lack of
enough water (quantity) or lack of access to safe
water (quality).
• It currently affects around 2.8 billion people around
the world, on all continents, at least one month out
of every year and more than 1.2 billion people lack
the access to clean drinking water.
• Every day in rural communities and poor urban centres throughout
sub-Saharan Africa, hundreds of millions of people suffer from a lack
of access to clean, safe water.
• Women and girls especially bear the burden of walking miles at a
time to gather water from streams and ponds -full of water-borne
disease that is making them and their families sick.
•Freshwater fish are going extinct at five times the rate
of marine fish species
•In the last 100 years 50% of the world’s
wetlands have been lost to development
India is facing a water crisis that has implications. not only
for its 1.1 billion people, but for the entire globe.

WTO
World Trade
Organization
The WTO’s predecessor, the general agreement
on traiffs and trade(GATT),was estabilsh after
world warII in the wake of other multilateral
institutions dedicated to Internationaleconomic
corporation.
GATT was the only multilateral instruement
governing international trade from 1948 until the
WTO was estabilshed on january1,1995.
The World trade organisation is an organizationthat intends
to supervise and liberaliseinternationaltrade.
WTO was officially commenced on january 1,1995
WTO was created by uruguay round negotiation(1986-94).
There are total 153 member countrries was counted in the year
2011.
Currently there aretotal 629 staff members are present inWTO
Budget 196 million swiss france in the year2011.
WTOreiteratestheobjectivesofGATT,some of
themareasfollows:-

INTRODUCTION
-TheKyotoProtocolisaprotocoltotheNFCCC,
aimed at combating globalwarming
-GOAL: stabilization of greenhouse gas
concentrationsintheatmosphereatalevelthat
would prevent dangerous anthropogenic
interference with the climatesystem
INCLUDES: a set of countryspecific reductionsof
emissions of "greenhouse" gases that absorb andre

HISTORY /OBJECTIVES
-Initially adopted on 11 December 1997 inKyoto;
-Opened March 1998 for signature by partiestoUNFCCC
-TheEUanditsMemberStatesratifiedtheProtocol in
May2002
-Entered into force on 16 February2005

'aimtoatleasthalveglobalCO2emissions by2050As
of October 2009, 184 states have signedand ratified
theprotocol
-A country can withdraw by giving 12months notice
All member countries give generalcommitments

HISTORY /OBJECTIVES
-ThetargetagreeduponwasanaverageGHG reduction
of 5.2% from 1990 levels by the year 2012.
-KYOTO plus set a national target to cut GHG emissions
at least25 % from 1990 levels by 2020
-The most notable nonmember of the Protocol is the US,
which is responsible for 36.1% of the1990 emissionlevels
-Japan, Canada, Italy, the Netherlands, Germany,

Aim of the Kyoto Protocol:
PRINCIPLE OF "COMMON BUT
DIFFERENTIATED RESPONSIBILITIES"
The largest share of historical and current global
emissions of GHG originated indeveloped countries
Per capita emissions in developing countriesare still
relativelylow
Share of global emissions originating in developing
countries will grow to meet socialand developmentneeds

There is a worry that some rich countries will simply 'buy off'
the GHG they produce and not take any action themselves.
The idea of a 'cap on the amount of trading has been
suggested, but has produced even more argument'. • Taken a
step further, per capita emissions have been discussed as a
Utopian way to be fair to all.. Maybe one day. But these
credits will only have value for reductions made in the
commitment period 2008-2012. • Despite this some traders
are already speculating in 'carbon credits' and its worth all
businesses being aware of where they would stand in a world
of 'carbon credits'. Farmers for instance may be sitting on
'pots of carbon gold' in the form of the potential of their land
as a carbon sink.
