  1. biodiversity hotspot?
    • It is an area unusually rich in biodiversity of birds and animals,
    • but they are under constant threat of overexploitation. Such an area is called a biodiversity hotspot
    • Example of biodiversity hotspots in India : eastern Himalayas, western Ghats etc
  2. Difference between a national park, wildlife Sanctuary, and a biosphere reserve
    • National Park
      • No human activity or settlement allowed.
      • Villagers cannot graze their animals,
      • Extremely strict rules about jungle produce collection (Tendu leaves, Honey etc.)
    • Wildlife Sanctuary
      • People are not allowed to live (some exceptions though) but some human activities are allowed, such as grazing, firewood collection.
      • Tourism is permitted.
      • A Sanctuary can be upgraded as a National Park. However a National Park cannot be downgraded as a Sanctuary.
    • Biosphere reserve
      • People are allowed to live, own private land and carry on their traditional activities. (In the outer-zone)
  3. DDT and Biomagnification
    • DDT=dichloro-diphenyl trichloroethane.
    • It is a “broad” spectrum pesticide (meaning it can kill variety of insects, not just one or two.)
    • It lasts for a relatively long time (nearly 20 years) after one application.
    • DDT is cheap to produce, been extensively used across world.
    • Problem: DDT cannot be metabolized (digested) by any living organism.
      • Suppose DDT was sprayed on water.
      • There are millions of planktons in the water.
      • Each of them absorbed 5ppm of DDT.
      • Since they cannot digest DDT, it remains unprocessed in their body.
        • A fish eats 8 such planktons, so it gets 8 x 5 =40 ppm of DDT in its body.
        • A bird eats 50 such fishes, so bird gets 40 x 50 =2000 ppm of DDT in its body.
    • So the amount of DDT keeps increasing as we move up in the food chain. This phenomenon is known as bio magnification.
    • Bio magnification is bad because it produces variety of diseases in the species + its offsprings (babies) via teratogenesis.
      Teratogenesis = formation of defective embryo.
  4. Carrying Capacity
    • It means the maximum population that an environment can support and sustain.
    • When the carrying capacity is reached, birth rates equal death rates and the population should maintain a steady state equilibrium.
  5. Nagoya Protocol
    • under CBD,
    • For sharing benefits from genetic resources.
    • Official name= Nagoya Protocol
    • on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS).
    • India has already ratified Nagoya Protocol on Access and Benefit sharing.

    • It is to be constructed on Kerala’s Chalakkudi river in Thrissur district.
      New LDF government wishes to construct but tribal and coalition partners are opposed.
  7. According to the 2015 census, there are 523 lions in the गीर region.
  8. India has 26 of the total 169 Ramsar wetland sites.

    • Maharashtra  has  become  the  first  State  in  the  country  to  have  a  ‘State butterfly’.
  25. Sangai 
    • The  Sangai  is  an  endemic,  rare  and  critically  endangered  subspecies  of  browantlered  deer  found  only  in  Manipur.   
    •   It is  also  the  state  animal  of Manipur 
    • Its  habitat  is  restricted  to  the  marshy  wetland  of  Keibal  Lamjao  over  the floating  biomass in  Loktak  lake  which  is  locally  called  ‘phumdi’.   
    • While  walking  on  the  floating  biomass,  Sangai  often  balances  itself  which  looks as  if  it  is  dancing  on  the  green  grassland  and  therefore  popularly  called  as ‘dancing  deer’  of Manipur. 
    • It  is  classified  as  ‘endangered’  by  the  IUCN  but  is  part  of  MoEF’s  ‘Recovery Programme  for  critically  endangered  species and  habitats’.
    • Reasons  for  Declining  Sangai  Population 
      • Change  in  water  regime  due  to  construction  of  artificial  reservoir  and  barrage. This  is  resulting  in  thinning  of  phumdi  which  is  unable  to  bear  the  weight  of deers. 
      • The  shelter  plants  are  stunted,  mainly  due  to  constant  floating  of  phumdis making  Sangai  vulnerable  to  poaching.
  26. Recently  following  animals  were  declared  vermins  –
    • wild  boar  in  Uttarakhand,
    • Nilgai in  Bihar and
    • Rhesus  Macaque  monkeys in  Himachal Pradesh.

    • also  known  as  Kashmir  Deer,  is  an  endangered  species  mainly  concentrated at  Srinagar’s  Dachigam  National Park.
  28. Particulate matter (PM)
    • PM 10,  which  are  smaller  than  10  microns  in  diameter,  enter  the  respiratory tract,  and  have  been  associated  with  risks  like  bronchitis,  asthma,  and  upper respiratory  tract  infections.  PM  10  aggravate  symptoms  of  existing  diseases more  than  triggering  new  conditions.    
    • PM  2.5  are  considerably  finer,  penetrate  into  the  lower  respiratory  tract  or deeper  in  the  respiratory  tract,  and  the  blood  stream,  causing  cardiovascular problems.  
    • PM 1,  which  are  so  much  finer  than  PM  2.5,  can  penetrate  the  cardiovascular stream  even  further,  and  give  rise  to  lasting  conditions,  such  as  predisposing people  to  heart  diseases.  
    • For the  first  time  in  the  country, PM1  was monitored during  the  odd-even traffic scheme  in  New  Delhi  
    • In  the  case  of  Delhi,  the  contribution  of  vehicles  to  air  pollution  is  quite  high. Certain  studies estimate  it  to  be  up  to  80%  of  the  total.  
    • Base noise levels in the  city  have  exceeded  acceptable  standards
