3. Abstract
•Ecosystems (i.e. suites of living species interacting with one
another and with their non-living environment) can be
considered as natural assets from which flow services that
sustain and fulfil human life. These “ecosystem services ”
include: provision of clean air and water, maintenance soil
fertility, regulation of climate, pollination of crops and
native plants, control of the vast majority of potential pests,
maintenance of genetic resources, provision of food, fuel and
fiber, and fulfillment of our lives through cultural, spiritual
and intellectual stimulation.

4. Introduction
•Ecosystem ecology is the study of these and other questions about
the living and nonliving components within the environment, how
these factors interact with each other, and how both natural and
human-induced changes affect how they function.
•Understanding how ecosystems work begins with an
understanding of how sunlight is converted into usable energy, the
importance of nutrient cycling, and the impact mankind has on
the environment. Plants convert sunlight into usable forms of
energy that are carbon based. Primary and secondary production
in populations can be used to determine energy flow in
ecosystems. Studying the effects of atmospheric? CO
2will have
future implications for agricultural production and food quality.

5. Aims and Objectives
•0ur aim for this research is
to find out how local
people, industries ect, are
taking the advantages of
ecosystem.
•What things are made or
created by people or
ecosystem itself .
•If usage of natural things
are more than needed .
Local People Industries
Societies or
Residence
Private or
Public Sectors

6. Hypothesis
1)Afforestation –Changes in the growth of trees and stands
result from regular changes in dominance and the efficiency
of resource use by dominant and non-dominant trees
2)Deforestation-The trees are important because we need
them for the oxygen. N0t just trees are dying, lots of
wildlife do not have enough oxygen to live and just die.
That's how many organisms deforestation has a big impact
on. How can we stop this? One way to stop this is just using
less paper. Paper is made from cut down trees. That’s why
if we recycle paper and keep reusing paper there would not
be more paper needed.

7. 3 ) Recycling -Waste items such as aluminum cans, paper
and cardboard, plastic bags and bottles, glass and foilare all
recoverable, which is why you put them into your curbside
recycling bin once a week and put them out for collection.
4) Using resources carefully -Are we using natural resources
properly? It is very important we userenewable and non-
renewable resources wisely. If a resource is used and thrown
away, eventually the resource becomes scarce. When the supply
dwindles, its price will increase. Products that are made from
that resource would increase in price too.

8. Methodology
It is a way of doing something
based on particular methods
and data.

9. The Following charts / Data shows the
Deforestation, Afforestation, Recycling over a
period of time.
In the above data ,we
can recognize that rate
of deforestation
increasing rapidly every
year because of need or
requirement by the
people.
In the above graph we
can recognize that the
rate of afforestation is
increasing but comparison
to felling it is still very
low and the time period
for growing tress are
10 –15 years .
In the above graph we
can see that the amount
of recycling in increasing
over a period of time.
But for saving our earth
we have to do more
efficient .

10. In this graph we can see that
the rate of tree cover loss by
years is increasing rapidly
because the population of
world is increasing. So, we
need more and more trees /
national resources to fulfill our
need but while using we waste
a lot of wood and other
resources.
Eg-If we organize a party a
lot food got waste but instead
of distributing it we through
it most of the time.
FELLING

11. IN THE NEXT SLIDES WE CAN SEE
WASTAGE VS RECYCLING

12. AVERAGE WASTE
GENERATED OVER
A PERIOD OF ONE
YEAR

13. RECYCLING
According to the graph aside
we can see that we recycle
almost all cars, lead, many
more. But we almost have to
maintain a ratio for things
that are no or less recycled like
plastic, glass ect. We have to
maintain a ratio between
everything we use or naturally
get .

14. WASTAGE
•According to the graph aside
we can know that wastage
of paper , glass is higher
than other materials. But
without them
CAN WE SURVIVE??

15. Be Carefull!!

16. Observations and Data Collection
In the following slides is the
information we collected
from local people, farmers,
doctors, people working in
private and public sector.

17. Name –Nagendra Singh
Occupation-Farmer
1)What is the ratio of manure and fertilizer you use?
2:1 (Manure : Fertilizer)
2) How much fertilizer / manure you use per 100 square feet?
2-3 pound of fertilizer
3) When you burn wheat , is it good for the soil?
Yes
4) Do you know burning of crops cause a lot of polluted air?
Yes

18. Name –Kishor Kumar
Occupation-Works In Newspaper Company
1)At an average how much copies does Amar Ujalause per day for
printing?
22.2 Million copies per day
2) How much paper get recycled by day at an average?
68.2 % per day at an average (Approx70%)
3)At an average how many daily readers Amar Ujalahave?
4.70 crore people (Approx50 crore)

19. Name-Dr Vinod Kumar
Occupation –Doctor (Clinic)
1)At an average how many prescription / paper you use per day?
40 –50 at a clinic.
2) Does all people prefer handwritten prescription or some prefer
soft copy ?
Mostly people prefer handwritten copy
3)What type of paper do you use for prescription , do u use any
of recycled paper ?
No, he use only good quality paper

20. Name –Rohit Yadav
Occupation –Owns a grocery store
1)How much paper do you use per day at the shop ?
He uses very less paper , he only use for printing bills if a
customer asks for it. Otherwise he do not use it .
2) How many customers you get at an average daily?
30 –40 ( It varies day to day )
3) Do you use paper bags , a bag of cloth or polythene ?
He prefers bag of cloth (costs RS 3-5) generally but at
times he prefers polythene .

21. Name –Raju
Occupation -Trash Collector
1)Does people separate dry and wet garbage?
No
2) Do all people use plastic bag or some use recycled paper bag
for garbage?
No, 99% of people use polythene for throwing garbage .
3) Does the govt provide you essential resources for collecting
garbage ect??
No , they provide good quality products .

22. Result
•As a result , we can say that the use of natural
resources (paper , wood) can vary work to work
and people to people but in every work it does not
matter if it is small or big . The thing is that how
much we can save or survive with ecosystem.
Can we survive without Ecosystem??
•Such as some children would use recycled pages for
doing rough work or practicing . On the other hand
many children prefer using classmate, lotus ectfor
rough work also .
“IN SHORT EVERTHING IS INTERCONNECTED”

23. Conclusion
•The conclusion about this problem is that the
population of the world is rising very fast, so to
match the need of population, we have to recycle
more and more things because cutting trees,
mining ores is not a way to handle it for long.
•Recycling is a solution but the main point is to use
less resources. Such as if you can walk or cycle 3
Km for buying groceries WHY NOT? , It is good for
your physical health as well as the ecosystem in
which live or if you can take the metro to reach
your office / destination WHY CAR?
“THE MAIN PROBLEM IS NOT USING RESOURCES
IT IS NOT USING THEM WISELY”

24. Solution
1) Reduce, reuse, and recycle. Cut
down on what you throw away.
Follow the three "R’s” .
2) Volunteer. Volunteer for
cleanups in your community. You
can get involved in protecting your
watershed, too.
3) Educate. When you further your
own education, you can help
others understand the importance
and value of our natural resources.
4) Conserve water. The less water
you use, the less runoff and
wastewater that eventually end up
in the ocean.
5) Shop wisely. Buy less plastic and
bring a reusable shopping bag.

25. 6) Use long-lasting light bulbs.
Energy efficient light bulbs reduce
greenhouse gas emissions. Also flip
the light switch off when you
leave the room!
7) Plant a tree. Trees provide
food and oxygen. They help
save energy, clean the air, and
help combat climate change.
8) Don't send chemicals into
our waterways. Choose non-
toxic chemicals in the home
and office.
9) Bike more. Drive less .

26. Iwould like to express my special thanks of
gratitude to my teacher MrsRanjana Kumari
as well as our principal MrsShobha Sharma
who gave me the golden opportunity to do
this wonderful project on the topic , which
also helped Significance of Forest Ecosystem
and Over use me in doing a lot of Research
and I came to know about so many new
things I am really thankful to them.
