Important questions on Biodiversity Conservation

The narrowly utilitarian arguments for biodiversity conservation include which of the following from the given list?
(i) Industrial products like dyes, lubricants
(ii) Ecosystem services like photosynthesis
(iii) Pollinators layer of bees, birds and bats
(iv) Firewood, fibre and construction material 
(v) The aesthetic pleasure of walking through thick woods 
(vi) Products of medicinal importance
(vii) Watching spring flowers in full bloom

A

(i), (ii), (v) and (vii)

B

(ii), (iii), (v) and (vii)

C

(i), (iv) and (vi)

D

(iii), (v), (vi) and (vii)

View Answer

The narrowly utilitarian arguments for conserving biodiversity are
obvious; humans derive countless direct economic benefits from nature food (cereals, pulses, fruits), firewood, fibre, construction material,
industrial products (tannins, lubricants, dyes, resins, perfumes ) and
products of medicinal importance. More than 25 per cent of the drugs
currently sold in the market worldwide are derived from plants and 25,000
species of plants contribute to the traditional medicines used by native
peoples around the world. Nobody knows how many more medicinally
useful plants there are in tropical rain forests waiting to be explored.
With increasing resources put into ‘bioprospecting’ (exploring molecular,
genetic and species-level diversity for products of economic importance),
nations endowed with rich biodiversity can expect to reap enormous
benefits.
So the correct option is '(i), (iv) and (vi)'.

Compare narrowly utilitarian and broadly utilitarian approaches to conserve biodiversity with the help of suitable examples.

View Answer

  • Narrow utilitarian approach for the conservation of biodiversity is because of all the advantages that human-derived from the biodiversity and the nature around it. It includes all the word commercial things that the forests provide us. A narrow utilitarian aspect usually deals with the benefits of the human.
  • The broad utilitarian method or approach for conservation of biodiversity is basically protecting the nature because of all the benefit and the moral responsibility that humans have towards nature.


Justify with example where a deliberate attempt by humans has led to the extinction of particular species.

View Answer

Threats to biodiversity are-
Destruction of habitat which leads to deprivation of shelter and food for animals. Pollution which is a subtle form of habitat destruction which may reduce and eliminate the population of sensitive species.
Introduction of exotic species- new species may kill or eat native species to the point of extinction or may alter the habitat that many natives are no longer able to persist. Disturbance and degradation of habitat-natural disturbances and degradation are caused by spontaneous jungle fire, pest infection deforestation, by an insect, locust attack etcetera. Man-made disturbances and degradation and more severe. They include felling of trees use of fire for clearing forest areas, a collection of litter and overexploitation for other economic important products point disturbances and degradation result in a loss of biodiversity.

Which one of the following strongly threatens biodiversity?

A

Destruction of mutual habitats and vegetation and shifting cultivation

B

Inaccessible habitats in the Himalayas

C

Fragile ecosystems such as mangroves and wetlands

D

Creation of biosphere reserves

View Answer

Loss of habitat or destruction which is a result of increasing human population in the region has put heavy pressure on the food requirements.
So, the correct option is 'Destruction of mutual habitats and vegetation and shifting cultivation'.

What are Sacred-grooves ?

View Answer

Sacred groves are tracts of forests that have religious significance for a community and hence, are protected by the community. They are helpful to the environment because due to their religious significance, no logging or hunting activity takes place there. Hence, these forests remain in their pristine form providing a safe habitat to many animal species. Hence, the area around such sacred groves is protected from environmental degradation.

Prepare some slogans or a pamphlet to make aware of people about conservation of biodiversity.

View Answer

  • Flora and fauna all are co-related, animals and flowers need not to be hated.
  • Don’t let species go extinct, in this world we are all linked.
  • Protect nature to be protected.
  • All for one and one for all, keep Biodiversity or our future may fall.

The Earth Summit held at Rio de janeiro in 1992 resulted into

A

Computation of Red List

B

Establishment of Bioshere Reserves

C

Convention on Biodiversity

D

IUNC

View Answer

the Earth summit which took place in Rio de Janeiro Brazil in 1992 was related to conservation of biodiversity which is a raging topic now.
So, the correct option is 'Convention on Biodiversity'

Wild Life of nature is renamed as

A

World Wild Life conservation of nature

B

World Wild Life of nature

C

World Wild Fauna

D

World Wild Life Fund

View Answer

The wildlife is a valuable resource of our country which needs to be protected from the threats imposed by human activities. Several regulatory bodies have laid certain formulations to protect them. The 'World Wide Fund for Nature' (WWF)  deals with the issues regarding the conservation, research, and restoration of the environment. It is an international non-governmental organization founded on April 29, 1961, and isIt was formerly named the 'World Wildlife Fund', which remains its official name in Canada and the United States. It is the world's largest conservation organization with over 5 million supporters worldwide, working in more than 100 countries, supporting around 1,300 conservation and environmental projects.
