SEVEN BILLION EXPECTATIONS,ONE PLANET
Ever-growing human demand for resources, however, is putting tremendous pressure on biodiversity. This threatens the continued provision of ecosystem services, which not only further threatens biodiversity, but also our own future security, health and well-being.
At our current rate of consumption, the Earth needs 1.5 years to produce and replenish the natural resources that we consume in a single year.
The current world population was 7,263,913,077
(check the site www.worldometers.info).
STATISTICS OF INDIAN POPULATION
Current Population of India in 20141,270,272,105 (1.27 billion)

THE LIVING PLANET INDEX
The living planet index reflects changes in the state of the planets biodiversity. The living planet index continues to show a 28 per cent global decline in biodiversity health since 1970 .
THE LIVING PLANET INDEX
The tropical living planet index declined by more than 60 per cent from 1970 to 2008, while the temperate living planet index increased by 31 per cent over the same period. Recent average population rises do not necessarily mean that temperate ecosystems are in better state than tropical ecosystems.
THE ECOLOGICAL FOOTPRINT
The ecological footprint tracks humanitys demands on the biosphere by comparing the renewable resources people are consuming against the earths regenerative capacity, or biocapacity. Both the ecological footprint and biocapacity are expressed in a common unit called a global hectare, in which one gha represents a biologically productive hectare with average productivity.
THE ECOLOGICAL FOOTPRINT(contd.)
In 2008, the earths total biocapacity was 12.0 billion gha, or 1.8 gha per person, while humanitys ecological footprint was 18.2 billion gha, or 2.7 gha per person.
THE ECOLOGICAL FOOTPRINT(contd.)
This discrepancy means that we are in an ecological overshoot situation: it is taking 1.5 years for the earth to fully regenerate the renewable resources that people are using in a single year. Instead of living off the interest, we are eating into our natural capital.
COMPONENTS OF ECOLOGICAL FOOTPRINT(contd.)
OUR ECOLOGICAL FOOTPRINT
How many 'Earths' worth of resources do we consume?
LINKING BIODIVERSITY, ECOSYSTEM SERVICES AND PEOPLE
Biodiversity is vital for human health and livelihoods. Living organisms plants, animals and microorganisms interact to form complex, interconnected webs of ecosystems and habitats, which in turn supply a myriad of ecosystem services upon which all life depends. Although technology can replace some ecosystem services and buffer against their degradation, many cannot be replaced.
Understanding the interactions between biodiversity, ecosystem services and people is fundamental to reversing the trends outlined in the previous pages and so safeguarding the future security, health and well-being of human societies.

Introduction
Is the world getting warmer?
If so, are the actions of mankind to blame for earths temperature increases?
What should be done about these issues?
In examining global warming, we will be looking at questions such as Is the world getting warmer? If so, are the actions of mankind to blame for earths temperature increases? What can or should be done about global warming? Are the potential resolutions to global warming worth the cost to implement them?
History of Earths Climate
Earth formed ~4.6 billion years ago
Originally very hot
Suns energy output only 70% of present
This is a big picture examination of the earths climate The Earth was formed around 4.6 billion years ago And was originally very hot However, the Suns energy output was only 70% of what it is presently Liquid water was present on the surface around 4.3 billion years ago
History of Earths Climate
Life appeared ~3.8 billion years ago
Photosynthesis began 3.5-2.5 billion years ago
Produced oxygen and removed carbon dioxide and methane (greenhouse gases)
Earth went through periods of cooling (Snowball Earth) and warming
The first life forms appeared ~3.8 billion years ago Photosynthesis began 3.5-2.5 billion years ago, which produced oxygen and removed carbon dioxide and methane, which are greenhouse gases, from the atmosphere As a result, the Earth went through periods of cooling, commonly referred to as Snowball Earth and subsequent warming Earth began its current cycles of glacial and interglacial periods around 3 million years ago

SolarEnergy
The temperature of the earth is directly related to the energy input from the Sun. Some of the Suns energy is reflected by clouds. Other is reflected by ice. The remainder is absorbed by the earth.

RadiationCooling
If amount of solar energy absorbed by the earth is equal to the amount radiated back into space, the earth remains at a constant temperature.

However, if the amount of solar energy is greater than the amount radiated, then the earth heats up.

If the amount of solar energy is less than the amount radiated, then the earth cools down.
Greenhouse Effect
Sun
To a certain degree, the earth acts like a greenhouse. Energy from the Sun penetrates the glass of a greenhouse and warms the air and objects within the greenhouse. The same glass slows the heat from escaping, resulting in much higher temperatures within the greenhouse than outside it.
Earths Atmospheric Gases
Nitrogen (N2)
Oxygen (O2)
Water (H2O)

Likewise, the earths atmospheric gases affect the ability of the earth to radiate the Suns energy back into space. Nitrogen and Oxygen make up 99% of the earths atmospheric gases and are non-greenhouse gases. Water, Carbon Dioxide, and Methane make up 1% of the earths atmosphere, but are greenhouse gases, since they cause the earth to retain heat.
Effects of global warming
Rising Seas
Changes in rainfall patterns
Melting of the ice caps
Melting glaciers
Widespread vanishing of animal population
Spread of Diseases
Hunger
Hunger is the uneasy or painful sensation caused by want of food; craving appetite.
The world produces enough food to feed everyone. World agriculture produces 17 percent more calories per person today than it did 30 years ago, despite a 70 percent population increase.
The proximate causes are
Poor weather
Low grain reserves
High oil prices
Carbon Footprint
A carbon footprint is a measure of carbon dioxide emissions
associated with an entity's
activities.
Effects of Carbon Footprint
Greenhouse Gas Emissions
Climate Change
Depletion of Resources
Plastic Pollution
Plastic pollution involves the accumulation of plastic products in
the environment.
Consequences
Plastic bags pollute
beaches & oceans. Plastic bags kill animals.
Plastic bags effect on
human health.Plastic bags are non-biodegradable.
Water pollution
Indroduction
Water pollution occurs when harmful substances are released into the water in large quantities which cause damage to people, wildlife, or habitat or indirectly into water bodies without proper treatment to remove harmful compounds.
Effects of water pollution
Water pollution is a major environmental issue in India.
The largest source of water pollution in India is untreated sewage
The Ganges River Pollution is now at such a high level that the amount of toxins, chemicals and other dangerous bacteria found in the river are now almost 3000 times over the limit suggested by the WHO as 'safe'.
How are we responsible?

ROLE OF AN ENGINEER
Engineers are not mere technicians and should not approve or
lend their name to any project that does not promise to be
beneficial to man and the advancement of civilization
-John Fowler
An engineer has big role to play as far ecological control is
concerned. Engineering is art of utilizing the great sources of
power in nature. It is a very vital organ for the benefit,
convenience and survival of mankind. The branch of engineering
involves manpower, money, materials, machines and energy.
Engineer plays important role towards environmental protection as
is evident from the following points :-
[1].He can help in selecting such a site which ;
(i) is pollution free
(ii) has less chances of atmosphere pollution
(iii) capacity to absorb pollutants.
(Iv) is gifted with sufficient quantity of pure water.
ROLE OF AN ENGINEER
[2].He can help in layout plan in such a way that
(i) atmosphere is not polluted.
(ii) pollution, if any, affect very few people.
(iii) pollutants do not move outside the factory but are absorbed
within the space available for factory.
ROLE OF AN ENGINEER
[3].He can plan out some space within the factory premises for
the disposal of poisonous waste material.
ROLE OF AN ENGINEER
[4].He can plan such a short route of disposal of pollutants in natural stream or rivers that the habitation and vegetation is least affected.
ROLE OF AN ENGINEER
OUR RESPONSIBILITY REVISITED
Carbon sequestration means capturing carbon dioxide (CO2) from
the atmosphere or capturing anthropogenic (human) CO2from
large-scale stationary sources like power plants before it is
released to the atmosphere. Once captured, the CO2gas (or the
carbon portion of the CO2) is put into long-term storage.
CO2sequestration has the potential to significantly reduce the
level of carbon that occurs in the atmosphere as CO2. There are two
major types of CO2sequestration:Terrestrial
Geologic
REDUCING CARBON FOOTPRINTS
TERRESTRIAL SEQUESTRATION
Terrestrial (or biologic) sequestration means using plants to capture CO2from the atmosphere and then storing it as carbon in the stems and roots of the plants as well as in the soil.
GEOLOGIC SEQUESTRATION
Geologic sequestration is putting CO2into long-term storage in geologic zones deep underground.
1. SOIL DATA CARD
Since India is an agricultural country , inorder for it to reach new heights there should be a boom in the agricultural field.
Having noticed this, Our Prime Minister Mr. Narendra Modi has focused entirely on soil health management.
Agriculture minister Mr.Rao proposed to start the massive programme called bhuchetana.It proposes that every farmer should know the quality of his/her soil and hence grow only those crops which the soil is suited for. The soil data card that will be produced will be computerized.
SOIL DATA CARD
2. ZERO DEFECT , ZERO EFFECT
Prime Minister Narendra Modi's "zero defect and zero effect" remark on 15th August,2014 came as a clear message that the country would not compromise on its goal of environmental protection.His categorical remark gives a clear message that the country will move on its low-carbon and sustainable growth trajectory while adopting clean technology and renewable energy in a big way.

4. USE BLACKLE
Blackleis a website powered bygoogle custom search and created byheap media , which aims to save energy by displaying a black background and using grayish-white font color for search results.
"Image displayed is primarily a function of the user's color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen."Roberson et al, 2002.
Google gets about 200 million queries a day. Blackle claims to save about 750-megawatt-hours a year. Hence,a substantial amount of energy would be saved.
