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).

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.

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.

Sun

Earths Temperature

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)

Carbon Dioxide (CO2)

Methane (CH4)

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.
