Biological
diversity or biodiversity means the
variety of life on Earth.It is the variety
between all species of plants , animals and micro-organisms and the
ecosystems within which they live and interact.Biodiversity and its
conservation are important for economic as well as for non-economic reasons.For
example , green plants remove
Carbondioxide and release Oxygen into
the atsmosphere.This helps to keep the environment fit and healthy for human life.This cannot be quantified in economic units but is extremely important.At the same time ,
economic arguments also provide compelling reasons for conserving biodiversity.
Different
species of plants , animals , and micro-organisms provide us with food ,
medicines, fuel,building materials,fibre for clothing and industrial products.Many species have
cultural , aesthetic and intrinsic values.For example, Blue Whales and Giant
Pandas have intrinsic values.Other services performed by ecosystems
include:1.Protecting areas from soil erosion , floods and other harmful weather conditions.2.Reducing the risk of
local and global climate change.3.Recycling nutrients.4.Pollination and
biological control.5.Controlling pollutants.6.Monitoring the health of
environment.
There are several
threats to biodiversity , as described below:1.Over exploitation of natural
resources. 2.Habitat loss and fragmentation.3.Poaching.4.Illicit
felling.5.Pollution.6.Climate change and Global warming.7.Growth of human
population.8.Hunting and illegal trade.9.I.A.S. (Invasive Alien Species)10.Lack
of efficient protection to threatened species.11Oil
spills.12.Coastal/agricultural development.13Land diversion 14.Encroachment.15.Fuel
wood removal.16.Grazing.17.Forest fires. All these threats have to be dealt
with in order to conserve biodiversity at local and global levels.Under Article
51A of Indian Constitution ,it is the fundamental duty of every citizen of
India to protect and improve the environment including forests,
lakes,rivers and wild life and to have compassion for living creatures.India
enacted The Biological Act ,2002 on February 5,2003 to provide for conservation
of biological diversity,sustainable use of its components, and fair and
equitable sharing of benefits arising out of the use of biological resources,
knowledge and for matters connected therewith.The conflict between biodiversity
and competing values are substantial.A
broader understanding of implications of biodiversity conservation
is needed for resource management
decisions.Managers need ways to evaluate the effects of their decisions in regional as well as in global context of
biodiversity conservation .
Education
is indispensable element for achieving
sustainable development(UN , 2002).The need to impart biodiversity education at all levels has been felt
at all international
initiatives.As per Unesco :”Education
for Sustainable Development allows every human being to acquire the knowledge,
skills, attitudes and values necessary to shape a sustainable future.

for Sustainable Development allows every human being to acquire the knowledge,
skills, attitudes and values necessary to shape a sustainable future. Education for Sustainable Development
means including key sustainable development issues into teaching and learning;
for example, climate change, disaster risk reduction, biodiversity, poverty
reduction, and sustainable consumption. It also requires participatory teaching
and learning methods that motivate and empower learners to change their
behaviour and take action for sustainable development. Education for
Sustainable Development consequently promotes competencies like critical
thinking, imagining future scenarios and making decisions in a collaborative
way.Education for Sustainable Development requires far-reaching changes in the way
education is often practised”
In the absence of widespread agreement on a philosophical approach and measurable results that describe the values of natural systems , resource managers have turned to public participation in their decisions in an effort to reach some sort of public consensus.Partly because of the requirements for public participation under the Environment Protection Act,there is now a substantial literature on ways to improve this participation .Analysis of alternatives, including economic valuations , might help to reduce the gap between contrary perspectives.Structured deliberation that involves stakeholders in these decisions and is supported by analysis will be useful in defining boundaries and directions.For such a informed decision making , it is important to catch citizens young and teach them the important subject of biodiversity from as many perspectives as possible.In Uttar Pradesh,it can help us understand and find solution to the problem of pollution of Ganga river water , especially by over 400 leather tanneries at Kanpur.We may understand better the global implications of declaring Pilibhit forests as Tiger Reserve.We may also analyze and decide better the Eco-sensitive Zones around different Protected Areas, especially the one around Okhla Bird Sanctuary near Delhi.

The word ‘Perspective means a particular
way of considering
something. Accordingly , there are a
number of perspectives on biodiversity.For example, gender inequality
perspective focuses on the number of women engaged in the study of biodiversity
as compared to men, and such other issues.
Multiple Perspectives
from which biodiversity can be considered for educating students are as below:
1.Scientific Perspective.
2.Historical Perspective.
3.Geographic Perspective.
4.Human Rights Perspective.
5.Gender equality Perspective.
6.Values Perspective.
7.Cultural Diversity Perspective.
8.Sustainability Perspective.
1.A scientific perspective is based on collecting , analysing and interpreting
empirical data about natural cycles and
phenomena.A scientific perspective is assumed to be context free.
2.A Historical
perspective helps learners how biodiversity issues have been addressed over
extended periods of time as well as in the present.Using evidence from past and
current situations , learners can understand how local and global
communities have made biodiversity
management decisions and the implications of those decisions.
3.Geographic perspective:This perspective enables
readers to understand how biodiversity issues appear and recur across a region,country,continent or Earth.By studying geographic scale of a
problem , we get deeper insights into the origin of the problem and potential solutions.
4.Human Rights perspective:Learning how quality of life can be affected by the relative health of biodiversity.This
requires that biodiversity is understood not as a purely economic good but also as a social or cultural good.All
societies need biodiversity to maintain
a quality of life consistent with
universal human rights .Projected needs
of future generations should also be considered , with planning for future
use and growth as integral components of
sustainability decisions.
5.Gender Equality perspective:Learning how gender roles
,social and cultural practices affect
decision making at different levels and in
using and protecting biodiversity at
different levels.How technology may have changed the context for gender related roles .For example,technology
has replaced the need for physical strength in completing many tasks.
6.Values perspective: learning about biodiversity across different values , with
the goal of finding a consensus position or action .
7.Cultural Diversity Perspective:Biodiversity issues
may be interpreted through unique world
views that are created through aesthetic or cultural ways of knowing.A cultural
perspective is often a unique perception associated with a particular
community.A cultural diversity
perspective considers the role of
biodiversity in the cultural community’s world view
8.Sustainability perspective:We consider the interactions between
the biodiversity , economics and society
to ensure sustainability for ecosystems and people today and for future generations.
The above are eight different perspectives identified by
Unesco , through which students can effectively learn an important subject like
biodiversity.We can use various methods to educate students about multiple
perspectives on biodiversity.
1.Viewing a documentary film
through different perspectives and sharing insights gives the entire
class a multiple perspective of the
issue.
2.Reading the same case study focusing on a particular biodiversity
topic.The students can analyze the case through the lens of a specific
perspective, and then share findings with their peers.
3.The students
may take up a local community biodiversity project,
investigate it deeper into what it means
at global level through a variety of
perspectives.Using their own community as a case study is likely to help students fully grasp the concept of
biodiversityIn the absence of widespread agreement on a philosophical approach and measurable results that describe the values of natural systems , resource managers have turned to public participation in their decisions in an effort to reach some sort of public consensus.Partly because of the requirements for public participation under the Environment Protection Act,there is now a substantial literature on ways to improve this participation .Analysis of alternatives, including economic valuations , might help to reduce the gap between contrary perspectives.Structured deliberation that involves stakeholders in these decisions and is supported by analysis will be useful in defining boundaries and directions.For such a informed decision making , it is important to catch citizens young and teach them the important subject of biodiversity from as many perspectives as possible.In Uttar Pradesh,it can help us understand and find solution to the problem of pollution of Ganga river water , especially by over 400 leather tanneries at Kanpur.We may understand better the global implications of declaring Pilibhit forests as Tiger Reserve.We may also analyze and decide better the Eco-sensitive Zones around different Protected Areas, especially the one around Okhla Bird Sanctuary near Delhi.
