3. Biodiverity
Meaning: The existence of a number of different
kinds of animals and plants which together make a
good and healthy environment is called biodiversity.
 Biodiversity describes the richness and variety of
life on earth. It is the most complex and important
feature of our planet. Without biodiversity, life
would not sustain.
 Biodiversity includes the number of different
organisms and their relative frequencies in an
ecosystem. It also reflects the organization of
organisms at different levels.

5. Value of Biodiversity
 . Biodiversity increases the productivity of the ecosystem. Each life form,
no matter how simple it is, has an important role to play in sustaining
life on the earth.
 Biodiversity is commonly defined in terms of species or groups of
independent living organisms that can produce offspring. Marine
mammals, fair-skinned deer, pine forests, fresh flowers, and micron-
sized bacteria that cannot be seen with the naked eye are some of the
examples of species that inhabit the earth.

6. Consumptive use
 Consumptive use : This refers to natural
products that are used for food, such as
livestock feed, wood products, fuelwood,
and other purposes. Humans consume
40,000 flora and fauna species daily. Many
people remain dependent on wildlife for the
majority of their necessities, such as
nutrition, temporary housing, and clothing.

7. Productive use
 Productive Use Value: Bamboos ,grasses ,canes
,essential oil, tanning material ,etc they have
there high commercial values. Almost all of
the crops grown today have evolved from wild
varieties.in additional to these various herbs
and animal body parts are sold in commercial
market , both at national and international
level.

8. Social values: The value of biodiversity distinct social value
attached with different socities . Materialistic uses of
biodiversity are the core of instrumental value. Goods and
services provided by ecosystem to our society include
(1) Provision of food, fuel and fibber.
(2) Provision of shutter and building materials.
(3) Purification of air and water
(4) Detoxification and decomposition of wastes.
(5) Generation and renewal of soil fertility, including nutrient
cycling.
Biological resources are the pillars upon which we
bind civilization. The loss of biodiversity threatens our
existance ie. social life. Thus protecting biodiversity is in
our self intenst

9. Ethical value
 Ethical value: Ethical or religious values is also one of
the indirect values of biodiversity. The ethical and
religious value of biodiversity is rooted in the
understanding that huminity is part of nature and that
we are just one species among others. All species have
an inherent right to exist. Religions also have an
significant impact on our attitude towards natural
resources. Ethical value is one of the non-use values,
which derive from human ethical considerations
relating to matters such as the extinction of
species and ecosystems.

10. 5.Aesthetic value
 Aesthetic value: The aesthetic value of biodiversity has been expressed in
many ways through art, poetry, songs, literature, music and dance. Forests
are closely linked with our relegion and culture. Human race has a great
evolutionary attachment with forests as our ancestors lived in forests.
Forests are nature's laboratories, where Scholars study natural sciences.
Many types of trees are worshipped in tribal and Hindu societies i.e.
Peepal, Bargad, Tulsi etc. Some animals like cow is worshipped by Hindus
in all over India. In series of this many birds, colourful butterflies,
mammals have great aesthetic value for human beings. Eco-tourism
generate large amount of revenue annually that gives the aesthetic value
of biodiversity. In this tourism people far and wide spend alot of money
and time to visit wilderness areas, where they enjoy the aesthetic value of
diversity.
