conservation of biodiversity today we are losing about 1,500 species every two month and this is a very huge number that is we are losing 15 that means 750 species every month it is impossible for nature to compensate for this rapid loss and therefore it becomes extremely important to conserve this threatened biodiversity but as for this conservation is the scientific management at its optimal level and derives sustainable benefit for both the present and the future and there are only two ways of conservation of biodiversity one is in situ and one is exiting in situ means on site while xe2 means off site conservation so what is in situ an ex situ conservation in serum first of all protection of species in their natural habitats is considered as in situ conservation so wherever they're living we are protecting them in their natural habitat examples are National Park wildlife sanctuary biosphere reservoir etc éxito conservation means protection in a place away from their natural habitats so we are bringing from the natural habitat to some other places and there then we are trying to protect them enter into other places for example Barnacle Gardens for example Zoo etc other some of the examples so let us talk about the in situ conservation in in pseudo conservation there are three methods one is National Park second is wildlife sanctuary and third is biosphere reservoir the main objective of the National Park is to conserve conservation of the species of a habit with minimal or very low intensity of human activities that means in national parks human activities are not allowed or this is the core zone so no personal sets in the park other than the public servant on duty and persons permitted by the chief Wildlife Warden wildlife sanctuary it is the conservation of species and habitats manipulative management that means if something is not going good then people can manipulate the things and then and there also no person results inside the part other than the public servant so this is also concluding core zone before an restauration zone while the biosphere reservoir is the conservation of natural reservoir and the improvement of the relationship between human and the environment so in this case both natural and human influence ecosystem exist together so it contains core buffer and restoration as well as transition zones these are some of the national parks in India and these are some of the photographs of the national parks from India these are some of the wildlife centuries in India so what is biosphere biosphere is the different different zones of one particular area which consists of three main leaves of three main zones like core area which is undisturbed and legally protected ecosystem so nobody is allowed inside the core area secondly buffer zone buffer zone is the area where human beings can interact with the with the animals and plants so it is dedicated to research and educational studies our activities and last one is a transition zone where the human beings are allowed to do any kind of any habitation agriculture trade air weak recreational or activities or any kind of activities which can occur there so these are three zones of the biosphere so what are the advantages and disadvantages of in situ conservation first of all it gives a long time long term protection secondly it is also better opportunity for the conservation as well as evolution and also it is cheaper and what are the disadvantages proper protection against environmental pollution may not be enough in natural type of ecosystem that means even after such protection they will be affected by the pollution let's talk about the ex situ conservation acts into conservation there are many things like genes Bank this is the particular area where we can store the genes of each and every species secondly barnickle garden these are some of the gardens where we can say we can conserve the plants from different different geographical areas next is the DNA technology that is we can manipulate the be any of these things and finally the tissue culture tissue culture means growing complete plant from one small tissue of the plant so this can be done easily with the help of a small battery and there is a media so we keep generally the tissue inside the media for some time and after several days then it started the the cells from the tissue starts growing and it forms the callus and finally there are roots coming from the callus and then the plant grows from only one piece of the tissue plant tissue so this is plant tissue culture similarly similar to this there is also animal tissue culture where we are growing different organs of the animals with the help of the tissues only so what are the advantages and disadvantages of X due to conservation it is also giving the long-term conservation secondly the species survive longer and may breed more offspring than usual and thirdly the quality of the offspring is improved because of the genetic techniques and so required breeding of hybrid species is also possible so we can mix two animals or two plants also disadvantage it is not a viable option for protection of the rare species due to human interference and it can be adopted only for few species not for all kind of species over production may result in loss of natural occurrence so these are some of the conservation methods you
