1. 3 R's Of Environment

2. Reduce
•
Reduce
:
to

make

something

smaller

or

use

less
,
resulting

in

a

smaller

amount

of

waste
.
•
"
Source

reduction
"
is

reducing

waste

before

you

purchase

it
,
or

by

purchasing

products

that

are

not

wasteful

in

their

packaging

or

use
.
•
A

key

part

of

waste
"
reduction
"
is

"
conservation
"
/

using

natural

resources

wisely
,
and

using

less

than

usual

in

order

to

avoid

waste
.

3. How to Reduce
Buy

products

that

can

be

reused
–
We

can

reduce

waste

by

using

a

computer
!
Many

newspapers

and

magazines

are

online

now
.
Instead

of

buying

the

paper

versions
,
you

can

find

them

on

the

Internet
.
–
Save

energy

by

turning

off

lights

that

you

are

not

using

4. Reuse
•
Reuse
:
to

use

again

or

more

than

once
•
Reuse

materials

and

items

so

that

they

have

longer

life

spans

and

don
’
t

get

thrown

away

after

the

first

use
.
•
Many

items

found

around

the

home

can

be

used

for

different

purposes
.
•
So

before

you

throw

those

items

away
,
think

about

how

they

can

be

reused
.

5. How to Reuse
•
Newspaper, cardboard and bubble wrap

Make useful packing material when moving house
or to store items.
•
Old clothes
Can be made into other textile items such as
cushion covers.
•
Scrap paper

Can be used to make notes and sketches.
•
Rechargeable Batteries

Can be reused many times before they need
throwing away

6. Recycle
•
Recycle
:
to

convert

materials
/
waste

into

reusable

material
•
Recycling

puts

objects

through

a

process
(
it

consume

energy
)
that

allows

them

to

be

used

again
.

7. How to Recycle
•
Example

Used plastic or metal objects can be
sold in scrap where they can be
recycled to create new usable
objects

8. Appropriate Technology
Technology should use less resources
and produce minimum waste
•
Conservation of energy:-
•
Conventional source of energy are
not renewable. Ex. Coal, Oil, Gas.
•
This also cause emmision of green
house gases like CO
2
.
•
It causes global warming.
•
Fossil fuel must be used more
efficiently

9. Appropriate Technology
•
Conservation of Water:-
•
Potable water is very limited. There
are areas in world where water is
scare commodity
•
Wastage of water is must be
prevented
•
It is necessary for sustainable growth

10. Appropriate Technology
•
Biological resources:-
•
Steps should be taken to prevent
natural vegitation, biodiversity, forest.
•
Lack of vegation will cause soil
erosion
•
Disturbance in biodiversity will affect
ecological system

11. Appropriate Technology
•
Reduction of pollution:-
•
Uncontrolled use of fossil fuel causes
air pollution.
•
Improper disposal of sewage water
will affect natural water resourses
and cause water pollution
•
Solid waste cause soil pollution which
affect fertility of soil
•
Hence reduction of pollution is
necessary

12. Appropriate Technology
•
Consumerism:-
•
People consume more than they
produce
•
US has only 4.7% of worlds
population but consume 25% of
worlds resources
•
Consumerism should be controlled
for sustainable development
