2 - Forest and Wildlife Resources

 1.  What is biodiversity? Why is biodiversity important for human lives?
  • Solution:Biodiversity is the degree of variation of life forms within a given ecosystem, or on an entire planet. There are millions of living organisms on planet earth. All these living organisms, including man, are interdependent on each other.
 2.  How have human activities affected the depletion of flora and fauna? Explain.
  • Solution:Cutting down of forests for agricultural expansion, large scale developmental projects, grazing and fuel wood collection and for urbanization has led to the depletion of flora and fauna.
 3.  Describe how communities have conserved and protected forests and wildlife in India?
  • Solution:In India many traditional communities still live in the forests and depend on their livelihood for forest produce. These communities are working hand in hand with the government to conserve forests.
    In Sariska Tiger Reserve, Rajasthan, villagers fought against mining activities. In Alwar district of Rajasthan, local communities belonging to five villages have set their own rules and regulations in 1,200 hectares of forest land. They have named it as the Bhairodev Dakav ‘Sonchuri’. Hunting is not allowed in these lands and outside encroachments are prohibited.
    The famous Chipko movement was started in the Himalayan region to stop deforestation. People belonging to the local community took to afforestation in a big way. Indigenous species were cultivated and protected.
    Involving local communities in protecting the environment, and stopping degradation of forests has reaped many benefits.
 4.  Write a note on good practices towards conserving forest and wildlife.
  • Solution:In 1972, the Indian Wildlife (Protection) Act was implemented. It made protecting specific habitats a law. A list of wildlife species that had to be protected was published and hunting these animals was against the law.
    National Parks and Wildlife Sanctuaries were set up in many states to protect endangered species.
    Under the Wildlife Act of 1980 and 1986, several insects have also been included in the list of protected species. Butterflies, moths, beetles, dragonflies and even certain plants are included in the protected list.
    "Project Tiger" was initiated in 1973 by the government of India to protect tigers. It is one of the most well publicized wildlife campaigns in the world.

Acids, Bases and salts extra qus

1.    What is an acid? Solution: An acid is a hydrogen-containing chemical compound which, when dissolved in water, gives hydrogen ion (H + ) or hydrated hydrogen ion (H 2 O. H + ) or hydronium ion (H 3 O + ).   2.    What are bases and alkalies? Solution: Oxides and hydroxides of metals and metal like radicals (e.g., NH4 +  ions) are called bases. Bases ionise to give OH -  ions in aqueous solution. Bases may be soluble or insoluble in water. The soluble bases are called alkalies. Thus all alkalies are bases but all bases are not alkalies. Examples NaOH and Cu (OH) 2  both are bases, but, since NaOH is soluble in water, it is an alkali. On the other hand, since Cu (OH) 2  is insoluble in water, it is not an alkali. Other examples of alkalies are KOH, Ca (OH) 2  and NH 4 OH.   3.    Define pH. Solution: pH of a given solution is the negative logarithm to the base 10 of the hydrogen ion concentration, [H +...

Project Tiger

Project Tiger  is a wildlife conservation movement initiated in  India  in 1973 to protect  tigers . The project aims at tiger conservation in specially constituted  tiger reserves  representative of various regions throughout India and strives to maintain viable populations of Bengal tigers in their natural environment. In 2008 there were more than 40 Project Tiger reserves covering an area over 37,761 km 2  (14,580 sq mi). Project Tiger helped to increase the population of these tigers from 1,200 in the 1970s to 3,500 in 1990s. However, a 2008 census held by the Government of India revealed that the tiger population had dropped to 1,411. Since then the government has pledged US$153 million to further fund the project, set-up a Tiger Protection Force to combat  poachers , and fund the relocation of up to 200,000 villagers to minimize human-tiger conflicts. The number of tigers in India's wild has gone up by 20%, according to...
