  1. Thanks For such a Great Explanation. You can also add how do we indulge or interact daily with this ecosystem.It would be better if you could tell viewer how are we going to be affected if this ecosystem is not balanced.And what can we do on daily basis to maintain environment like giving up our anti environmental habits.you should give a clear conclusion in last that we have to be aware about our environment and why it is so important to us.

  14. Yes Ma'm the blog is very useful...
    .I agree with you.......
    I got a good knowledge .....

    But I would like to add this thing......

    Now the main matter which you have to paste there is............

    Undoubtedly the blog is very useful and full of knowledge as well. But
    I will like to add one basic feature which is people often get
    confused between Wild life sanctuaries and National Parks…
    I am trying to differentiate in both of them ......

    WILD LIFE SANCTUARIES

    1. Basic feature: Established under the care and governance of
    Governor of state.

    2. Under the judicially of High court of the state

    3.IMPORTANT point: Here only living objects are reserved or protected.

    4. Local Citizen’s are allowed to use the resources @ not affect the
    sanctuaries structure permanently. i.e. they can use grass, and the
    wood of that place
    EX: Annamalai sanctuary, keoladeo bird sanctuary, Manas wildlife sanctuary.


    NATIONAL PARKS
    1.Established under the care and governance of President.

    2.Under the judicially of Supreme Court of India

    3.While in National Park both living and dead objects are protected
    and reserved.
    An Example: You can’t even remove a stone which is lying in the way
    without official order because it will kill the insects which are
    live under that stone.

    4.Not permissible at all.
    EX: Kanha Nationa Park, Dudhwa National Park etc.
