WHY WE CONSCIOUSLY AND SUBCONSCIOUSLY DESTROY OUR PRECIOUS ENVIRONMENT WITH THE INTENT OF MAKING LIFE EASIER AND ALSO GENERATING ECONOMICAL BENEFITS.

2. Introduction
IT IS A WELL-KNOWN FACT THAT HUMANS HAVE BEEN LIVING AND MODIFYING THE
EARTH SINCE THE BEGINNING OF TIME
WE CONSCIOUSLY AND SUBCONSCIOUSLY DESTROY OUR PRECIOUS ENVIRONMENT WITH
THE INTENT OF MAKING LIFE EASIER AND ALSO GENERATING ECONOMICAL BENEFITS.
THE FUTURE OF THE EARTH REMAIN UNCERTAIN DUE TO THE DAMAGING IMPACT THAT
ARISE FROM INDIVIDUALS QUEST FOR FULFILLMENT, ECONOMIC ADVANCEMENT AND A
LACK OF RESPECT FOR THE ENVIRONMENT.
YET TO ALL ALARMING SITUATIONS ,SUCH AS GLOBAL WARMING , UNTIMELY CHANGE OF
THE SEASON,OZONE DEPLEITON ,EXTICTION OF MANY SPECIES AND MANY MORE .WE
HUMAN’S STILL ENJOY OUR DOMINATION OVER THE PLANET AND EXPLOIT THINGS
ACCORDING TO OUR NEED
IF THIS CONTINUES ITS EXPECTED ,WE WILL BE PACKING UP WITH OUR NATURAL NON-
RENEWABLE SOURCES OF ENERGY ,NO SUFFICIENT LAND EVEN TO GENRATE RENEWABLE
ENERGIES ,TEMPRATURE OF THE EARTH WILL RISE TO 5 TO 8 DEGREES,ONLY THE SPECIES
LEFT WOULD BE INSECTS AND HUMANS ,GLACIERS WOULD MELT COVERING HALF THE
PRESENT LAND WITH WATER

3. Impact of human on environment with their respective
Era’s of Evolution .
Human evolution with time Change in human’s activity
with time
Humans were mostly hunter gatherers Hunting & food
gathering
Agriculture revolution Settlement and agriculture
development, domestication of animal,
habitat development
(urbanization)
Industrial revolution Development of industrial
process, mining and fossil fuel
production , increase the use of
pesticide and chemical fertilizer .
Scientific advancements & Globalization Rapid technology and information
development, globalization on many
aspects

4. Agriculture revolution
• SETTLED AGRICULTURE HAS INCREASED FOOD SUPPLY THAT LEAD TO
SUPPORT MORE PEOPLE, BUT DECREASE THE ENVIRONMENT QUALITY
• PEOPLES CUT DOWN VAST FOREST TO SUPPLY WOOD FOR FUEL AND
BUILDING MATERIAL THUS LEADING TO SOIL EROSION
• PLOWED UP LARGE EXPANSES OF GRASSLAND TO GROW CROP TURNING
FERTILE LAND TO DESERT

5. Effect of modern agriculture on the air, soil, water
& biodiversity resources
Water pollution SOIL Air pollution
 Aquifer deplition  Erosion  Green house gas emission from
 Increased runoff & flooding form  Loss of fertility Fossil fuel use
land cleared to grow crops  Stalinization  Other air pollutants from fossil
 Sediment pollution from erosion  Lateralization fuel use
 Fish kills from pesticide runoff  Water logging  Pollution from pesticide sprays
 Desertification
 Loss and degradation of habitat
from clearing grasslands & forests
 Fish kills from pesticide runoff Human health
 Killing of wild predators to protect
livestock  Nitrates in drinking Water
 Loss of genetic diversity from  Pesticides residues in food, air
replacing thousands of wild crop & water
strains with a few monoculture  Contamination through livestock
Biodiversity loss strains waste
 Bacterial contamination of meat

6. Raising livestock to produce meat & animal products by
open grazing is destroying ecosystems LIGHTLY
GRAZED
OVER
GRAZED
DUST STORM IN DELHI SORRY NOTHING TO FEED

7. Industrial revolution
• SHIFT FROM RENEWABLE ENERGY SOURCES TO NON-RENEWABLE ENERGIES
( FOSSIL FUELS). PRODUCTION NOW TOTALLY DEPEND UPON AVAIBILITY OF
THESE ENERGY RESOURCES.
• TO MEET THE CHANGE MAN STARTED UPROOTING THESE RESOURCES
BACKWARDING SUSTAINIBILITY OF ENVIORMENT
• APETITE & GREED FOR THESE RESOURCES SUDDENLY INCREASED AS HUMAN
CIVILIZATION MARCHED TOWARDS URBANIZATION AND SO DO WE STARTED
TO EXPLOIT
• WITH USE OF THESE NATURAL ENERGY RESOURCES , WE ACHIVED MANY
ADVANCEMENTS WITH TECHNELOGIES BUT AGAIN SIDELINNING THE
BY-PRODUCT , “POLLUTION”

8. Effects of extracting, processing and using of mineral / fossil
fuels
STEP Environmental effect
Disturbed land: mining
Mining accident ,health hazards, mine
exploration & extraction waste dumping, oil spills &
blowouts noise ugliness, heat
Solid waste: radioactive
Processing material air, water& soil
Transportation, purification, pollution, noise, safety &
manufacturing health hazards, ugliness, heat.
Uses Noise: ugliness thermal water
Transportation, pollution, pollution of air, water
transmission to individual & soil, soil & radioactive waste:
uses eventual use & safety &health hazards, heat
discarding

9. Effects of human activity on biodiversity
Habitat
Excessive loss POPULATION
resource use Over
fishing Habitat
degradation
Climate Basic causes
change • Population growth Introducing
• Rising resources use nonnative
• No environmental species
accounting
pollution • poverty
Commercial
hunting&
Predator poaching
& pest Sale of exotic
Land control pet& decorative
degradation plant

10. Consequences of excessive use of fossil fuels on environment &
the animals
Surface and subsurface mining cause
pollution and degradation of stream
and groundwater by runoff of acids
Burning fossil fuels produces billions
tones of CO2, one of greenhouse gases
that contribute global warming.
 A large amount Liquid fossil fuels can
seeps into ocean
 Waste oil dumped from activities on land
 Thus this oil leakage into oceans causes a
sudden collapse in marine ecosystem

11. Activity
Today the depth in which we had intervene the
earth’s natural cycle ,is to a extent that most of
the activity carried by us causes direct or indirect
harm to the environment
Even just a construction of road could lead
in destruction & degradation of land & the
ecosystem
Use of pesticides for controlling pest population
Its not only disbalances the natural cycle of insect
& their predators but also leads to soil infertility.
Further these insecticide travel up in the food
chain

12. ACTIVITY
Irreversible damage is being caused to soil due to various human activities mainly due to
Agriculture and industrialization
Today , though we understand the effect of which we had exploited the earth , still we are
landing towards the more worst conditions .
Soil Degradation Areas of degraded soil of the world

13. Overloading of waste in water to causing water
degradation
Only a tiny amount of world’s abundant water is available as fresh water (2.6%)
Rate at which water is being used is much faster then at which its replenished itself.

14. Our future sustainability
CLIMATE CHANGE WILL HAVE A SIGNIFICANT IMPACT ON THE SUSTAINABILITY OF WATER
SUPPLIES IN THE COMING DECADES. A NEW ANALYSIS, PERFORMED BY CONSULTING
FIRM TETRA TECH FOR THE NATURAL RESOURCES DEFENSE COUNCIL (NRDC), EXAMINED
THE EFFECTS OF GLOBAL WARMING ON WATER SUPPLY AND DEMAND IN THE
CONTIGUOUS UNITED STATES. THE STUDY FOUND THAT MORE THAN 1,100 COUNTIES --
ONE-THIRD OF ALL COUNTIES IN THE LOWER 35 -- WILL FACE HIGHER RISKS OF WATER
SHORTAGES BY MID-CENTURY AS THE RESULT OF GLOBAL WARMING. MORE THAN 400
OF THESE COUNTIES WILL FACE EXTREMELY HIGH RISKS OF WATER SHORTAGES

15. Climatic change : Again due to human
activities
Today our planet is hotter to 2 degree Celsius as compared to what was in the start of
industrial revolution.
It doesn't sound like much, but relatively small fluctuations like that can have a
significant impact over a wide surface. A 5 degree to 8 degree rise in global temperature
in the next 50 years, expected by many scientists, could cause sea levels to rise half a
meter and put some island nations underwater
Tough a concrete jungle are providing a good habitat for human’s ,but it bifurcates the
Law of natural cycle .

16. Man –vs - Animals
HUMAN’S AGAIN DOMINATED THE EARTH WITH THEIR ABILITY AND SKILLS IN
MANIPULATING & MODIFYING THE EARTH’S NATURAL SYSTEM
HUMAN’S STARTED TO HUNT AND DOMESTICATE ANIMALS SO AS REQUIRED
ANIMALS DOMESTICATED ,NOW COULD NOT SURVIVE WITHOUT HUMAN INTERFEARENCE
DUE TO EXCESSIVE HUNTING MANY ANIMAL SPECIES HAD EXTINCT OR ON A VERGE OF
EXTINCTION
LIFE WITHOUT
HUMAN’S -
IMPOSSIBLE

17. SCIENTIFIC ADVANCEMENT’ S &
GLOBALISATION
CREATING AND INTRODUCING NEW TECHNOLOGIES MUCH FASTER THAN WE CAN
EVALUATE THEIR IMPACTS
PRESENT IT SECTOR DEVELOPMENT ARE CAUSING CONFUSION, DISTRACTION AND
SENSE OF HOPELESSNESS AS RAPIDLY GROWING ENVIRONMENTAL INFORMATION
INCREASE ENVIRONMENTAL DEGRADATION AND DECREASE CULTURAL DIVERSITY AS A
GLOBALIZED ECONOMY SPREADS OVER MOST OF THE EARTH
THOUGH RAPID DEVELOPMENT & URBANIZATION IS THE CAUSE OF ALL THE PRESENT
SCENARIO OF ENVIRONMENTAL UPSET, IT IS ONLY THE CAUSE THAT PEOPLE ARE
UNDERSTANDING AND EXCHANGING THEIR THAUGHTS FOR SAVING THE ENVIRONMENT
