Assignment on Technical words:
An Ecosystem is a region with a specific and recognizable landscape form, such as forest ,grassland,desert,wetland or coastal area.
Ecosystems are the basis of life itselfs!
Ecosystems act as resource producers and processors.
Solar energy is the main driving force of ecological system,providing energy for the growth of plants in forests ,grasslands and aquatic ecosystems. Land itself is a most important Natural resource. It is necessary for foood production,animal husbandry,industry,and for our growing human settlements. Non-renewable resources are minerals that have been formed in the Lithosphere over millions of years and constitute a closed system. These non-renewable resources, once used,remein on earth in a different form and unless recycled properly,become waste material like oil and coal;Although water and biological living resources are considered renewable, they are ,infact,renewable only within certain limits. The Diversity of life on earth is so great that if we use it sustainably we can go on developing new products from Biodiversity for many generations.
Biological Diversity deals with the degree of nature’s variety in the biosphere.The loss of forest cover ,coupled with the increasing release of carbondioxide and other gases through Industrialization,contributes to the “Green house effect”.
|emigration - migration from a place (especially migration from your native country in oEmigration, forced or chosen, across national frontiers or from village to metropolis, is the quintessential experience of our rder to settle in another)|
glacier is a river of water in a solid state; a mass of ice in constant movement with a certain speed depending on the slope and volume.
The glacial ice is the product of the accumulation of snow throughout the centuries. Due to its own weight, the air trapped between the intergranular spaces is liberated.
The main conditions to enable the formation of a glacier are great snowfalls, and a mean annual temperature which may preserve the ice consistency.
Demographic transition is the shift in a population from an old demographic situation marked by natality and mortality that are high and that approximately balance out, to a modern demographic situation in which natality and mortality are low and also approximately balance out. During the transition, mortality is lower than natality and the population grows fast.
The relocation of people from one country to reside in another. People emigrate for many reasons, include increasing one's chance of employment or improving quality of life.
Emigration affects the economies of the countries involved. When people leave a country, they lower the nation's labor force and consumer spending. On the other hand, the countries receiving the emigrants tends to benefit from more available workers, who also contribute to the economy by spending money.
Capable of being broken down (decomposed) rapidly by the action of microorganisms. Biodegradable substances include food scraps, cotton, wool, wood, human and animal waste, manufactured products based on natural materials (such as paper, and vegetable-oil based soaps)
Urbanization can be defined as the rapid and massive growth of, and migration to, large cities. Positive and negative consequences resulted.
Urbanisation or urban drift is the physical growth of urban areas as a result of global change
Urbanisation is when people move into the city from the country, but they have not lived in the city before.

ANNA HAZARE'S MOVEMENT
A new landmark in the history of independent India,a new path paved by the anti-corruption campaigner Anna Hazare.His struggle against corruption is a gentle remainder of Mahatma Gandhi's satyagraha.Anna Hazare is wagging a peaceful non-violent war against corruption in India.His urge to free India from greatest devil,corruption,commends appreciation.His fight against corruption is not a one man show but people from all over India supported him.The greatest merit against the non-violent struggle is that no political party is involved in it.Anna hazare and his supporters are not influenced by any political party.
There was only one flag waving high in the sky and in our minds the Indian national flag.According to Jan lokpal bill there will be a separate body to investigate and club the ugly face of India-"CORRUPTION" where people have the right to raise their voice against corrupt politicians.Therefore the bill if enacted will act as the most powerful weapon in the war against corruption.
The main theme of the movement i,e.. anti-corruption is welcomed by every one because it is slowly sucking the blood of this country.It is also a constitutional as the parliament has passed the prevention of corruption act 1988.Neverthless the method adopted by Ana Hazare may be effective but not constitutional.Today Anna is a beacon of hope for the millions of fellow Indians filled with years of pent-up frustations on the issues of corruption.Anna has become the new leader of million of Indians in all walks of life in possibly the greatest public uprising against corruption since the time of independence.
thank you sir,

G.SARIKA, CSE 2B.
Good Evening Sir.I'd be pleased to share some points on today's session on environmental science:
1) We began our session with "air".That is the composition of various gases in air that is carbon dioxide and oxygen. And the mechanism of breathing was also taught by you.
2)The next was the "sapthashudhhi mantra".
3)We breathe 18 times per minute.
4)Hurry, worry increases our Carbon dioxide that comes out.
5)You mentioned about your poetry “UNDEVIDED EARTH'.
Wherein you spoke about how will the earth be without human beings, and just animals and other creatures around!!.
THE UNDIVIDED EARTH
If the whole human race disappears
From the worldly earth
Without the slightest trace
In a moment machines will run and burn
The trucks will hit and stop
Flying crafts will dash down
Within days, these places
Where I sat and slept
Will go to the ants and rats
In months my house and land
Will be free for cats and dogs
Let the animals enjoy!
The muddy heaps all around
With the earthy smell
Will cheer the plants
In years the trees will work havoc
Buildings will collapse
Multi flats will become hillocks
Bridges will break down
Roads will become valleys
And metros will sink in water
Fish will swim free
In the streams on the street
In bliss of the new found land
The nice earth with no boundaries
Only rivers and mountains
Plants unshaved and untrimmed
Animals free with no belts and ties
Where pets and wild don't differ
And permitted to roam around free
With no humans around
The world has no name
Only the earthly life
GOD, grant me another birth
With less of brain
And more of heart
To live free and fair
To see the earth
As the undivided one!!!
6)Then we moved on to the topic,'scope of the environment', where we spoke about atmosphere, hydrosphere, lithosphere and biosphere.
7)The next topic was, what actually environmental science is all about:
a) Systematic understanding of our environment.
b) Highly interdisciplinary.
e) Mission- oriented.
f)essential to study to overcome "environmental crisis".
8)Next, the objective were brought to limelight:
9) i came to know that a buffalo's stomach contained 300kg of plastic!!.
10)We were told that “The Great Global Warming Swindle” is a polemical documentary film that suggests that the scientific opinion on climate change is influenced by funding and political factors, and questions whether scientific consensus on anthropogenic global warming exists..
11) Al Gore, Pachauri's IPCC share peace Nobel. Al Gore
was the man who won noble prize for his movie 'An Inconvenient Truth’ which was picturised on Global warming.
12) We were told about The Kyoto Protocol is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC), aimed at fighting global warming.
13) Our next topic was 'Carbon trading'.
14) You even spoke of changing the name from 'Global warming' to 'Local city warming'.(which you strictly prohibited us to write in exams).
15) Only 54% of people in India get electricity!.
16)Farming without motor and using genetically modified seeds is called "ORGANIC FARMING".
17) Then we were told about Agnihotri and how usage of copper vessel kept diseases away.
18)10 wells=1 pond.
10 ponds=1 river.
10 rivers= 1 son.
10 sons=1 tree.
19) At last we were shown some pathetic videos on"animal killing".
Thank you so much Sir,its an honor to have somebody like 'you' as our guide and teacher.
vImportant Points Discussed Today are:
Importance of Environmental Studies
% of CO2 & Oxygen we are inhaling
Difference b/w Human beings & Animals
· Human is a social being
· Similar things in both:Food,Sleep,Sex
Environment means “me and my surrounding”
Different levels of atmosphere
Environer:condition that surround an organism
Famous movie:The Great Global Swindle
Population=>main reason for environmental pollution
· Cradle to cradle design
· Source reduction
Ozone Depletion Layer
Increasing Temperature(in just duration of 4 months e.g.,New Delhi)
30% people uses 70% facilities whereas 70% people uses only 30% facilities

· Today we had a class conducted on environmental studies by Dr.T.P.Sasikumar sir.
· Environment is what surrounds a thing or an item.
· Environment includes HUMAN BEINGS.
· Glacier is solidified ice.
· On the top of Himalayas the oxygen is less hence it becomes difficult to respire and a person starts bleeding.
· In atmosphere we have 0.03% of carbon and 20% of oxygen.
· We have 4 layers surrounding the earth 1)atmosphere2)hydrosphere3)lithosphere4)biosphere
· Atmosphere varies from 142kms-145kms.
· Hydrosphere: earth composed of water bodies.
· Lithosphere : outer shell of earth composed of crust and rigid outermost matter.
· Biosphere :
· Objectives of EVS:
a)creating awarness about our environment.
b)knowledge of our surroundings .
· Importance of EVS are:
· Evs enlighten us about the importance of protection and conservation of our environment.
· Evs have become significant for the following reasons:
· Environment issues being of international importance.
· Explosive increase in pollution.
· Need for an alternative solution.
· Need to save humanity from extinction.
· Need for wise planning of development
· Problems cropped in the wake of development.
· We had a discussion about carbon trading.
· Global warming which actually means LOCAL CITY WARMING.
· We have discussed the benefits of EVS.
· Conservation of energy and fast depleting natural resources.
· Increase in economic producting.
· Creaing awarness to control population.
· Global warming,acid rain,deforestation,water pollution,increase of population are the global environmental problems.
· Wind,water are renewable sources whereas coal is non renewable sources.
· Depletion of non renewable energy sources is also a major problem.
· So we need to create public awarness on environment.
· Environment protection is every individuals obligation and duty.
· Reformative measures if not under taken would result in extinction of life.
· We discussed on Green technology.
· Green technology means evolving group of methods and materials for generating energy to non toxic cleaning products.
· Sustainability:learning with nature.
· Most of the pollution is caused from cities and not from the villages.
· 54% of the villages are not electrified,they are under darkness.
· 70% of common people get 30% of resources while 30% of higher class people get 70% of resources.
· A mantra saptha sudhi.
· A part from environment studies we had a discussion on general and useful topics.
· How is a man better than the animals.
· We had been shown a video on how meat is produced.
· From the video we realized how unkindly the poor animals are killed and we thought of stop eating the non-veg from today.
· We had been shown a slide of 20 points to how to be a good student and we try to implement them.
