Ecosystem ki raksha
Short mein jawab
Ecosystem tab santulit rehte hain jab kriyaayein populations aur sansaadhanon ko sthir rakhti hain, par ek badlaav poore jaal mein fail sakta hai, jaise mendhak ki taangon ke export se keet badhe. Ecosystem hawa, paani, bhojan aur davaaiyaan dete hain, phir bhi Sundarbans jaise kai khatre mein hain. Sanrakshit kshetra, samajhdaari se upyog aur tikaau kheti unhe swasth rakhte hain.

Ek badlaav doosra laata hai
Prakriti mein chhota badlaav shaayad hi chhota rehta hai. Agar pradooshan talaab ke paudhe maar de, to kam oxygen banti hai aur machhliyaan marti hain; unhe khaane wali machhliyaan kam hone se keede badhte hain aur paas ke kheton tak failte hain, aur kisaan keetnaashak daalte hain, jo paryavaran ko aur nuksaan pahunchaate hain.
Ek asli misaal: 1980 ke dashak mein Bharat ne bahut saari mendhak ki taangein export ki, zyaadatar Indian bullfrog ki. Mendhak ghatne par unke khaaye jaane wale keede kheton ke keet ban gaye, isliye kisaanon ne zyada rasaayanik keetnaashak daale, jisse mitti, paani aur sehat ko nuksaan hua. Phir Bharat sarkaar ne mendhak ki taangon ke export par roak laga di.
Ecosystem tab santulit hai jab uske sadasyon ki kriyaayein populations aur sansaadhan dono ko sthir rakhti hain. Ye santulan gatisheel hai: ye badalta rehta hai aur praakritik ya insaani badlaav se bigad sakta hai.
Santulan rakhne wale rishte
Jeev bhojan, paani, jagah aur dhoop ke liye hod karte hain, aur ye pratispardha kisi ek prajaati ko bekaabu badhne se rokti hai. Doosre rishte bhi mayne rakhte hain. Sahopakaarita mein dono ko faayda hota hai, jaise madhumakkhi ras paati hai aur phool ka paraagan hota hai. Sahbhojita mein ek ko faayda aur doosre par asar nahi, jaise ped ka sahaara lene wala orchid. Parjeevita mein ek ko faayda aur doosre ko nuksaan, jaise kutte ka khoon choosne wala kilni (tick). Vanyajeev vaigyanik A.J.T. Johnsingh ne Bandipur National Park mein dikhaaya ki baagh aur tendue hiran aur jungli suar jaise shikaar ki swasth aabaadi par nirbhar hain.
Ecosystem hamein kya dete hain
Jungle taazi hawa, upjaau mitti, bhojan, resha, lakdi aur davaaiyaan dete hain; talaab, nadiyaan aur jheelein paani aur bhojan deti hain; aur sabki apni sundarta aur manoranjan ka mahatva hai. In sansaadhanon ka zyada ya galat upyog us santulan ko bigaadta hai jis par hum nirbhar hain.
Khatre mein Sundarbans
Sundarbans, jahaan Ganga aur Brahmaputra Bharat aur Bangladesh ke beech samudra se milti hain, duniya ka sabse bada mangrove jungle hai aur kai sankatgrast paudhon aur jaanvaron ka ghar hai. Iske ped toofaani hawaaon, lehron aur baadh ki taakat todte hain aur carbon dioxide lete hain. UNESCO ne ise 1987 mein World Heritage Site ghoshit kiya. Phir bhi mangrove eendhan aur kheti ke liye kaate jaate hain, jaanvaron ka avaidh shikaar hota hai, aur udyogon ka kachra aur bina saaf kiya seevage nadiyon ko pradooshit karta hai.
Sanrakshit kshetra
Sanrakshit kshetra vanyajeevon aur unke ghar ki raksha ke liye alag rakhi zameen ya paani hain: national park, biosphere reserve, vanyajeev abhyaaranya aur samudaay sanrakshit kshetra. Ye sankatgrast jaanvaron aur durlabh paudhon samet poore aavaas aane waali peedhiyon ke liye bachaate hain.
Prakriti ke saath kheti
Machhli ke talaab, khet aur park insaan ke banaaye ecosystem hain jinhe dekhbhaal chahiye. 1950 se 1965 ke khaadya sankat ke baad Green Revolution mein tractor, rasaayanik khaad aur keetnaashakon ne utpaadan badhaaya. Par lambe samay tak zyada upyog mitti ke sookshmjeev aur humus ghataata hai, jisse mitti ka kataav hota hai; keeton ke praakritik shikaari marte hain aur keet pratirodhi ho jaate hain; bhaari sinchaai bhoojal khaali karti hai; aur ekal kheti jaiv-vividhta ghataati hai aur pollinators ko nuksaan pahunchaati hai. Jaivik aur praakritik kheti, compost aur jaivik khaad, jaise praacheen granth Vrikshayurveda mein bataaya gaya Kunapa Jala, fasal chakra aur praakritik keet niyantran mitti aur hamari khaadya suraksha bachaate hain.

Students ke sawal
Bharat mein ecosystem ko kis cheez se khatra hai?
Jungalon ki kataai, praakritik sansaadhanon ka zyada upyog, aakraamak prajaatiyaan, bina soche zameen ka upyog aur pradooshan, jo jungle, nadiyon, jhaadiyon, nam-bhoomi, ghaas ke maidaanon aur tat ko nuksaan pahunchaate hain.

Green Revolution wali kheti ab tikaau kyon nahi maani jaati?
Rasaayanik khaad aur keetnaashakon ke zyada upyog, bahut zyada bhoojal nikaalne aur munaafe ke liye ek hi fasal ugaane ki wajah se. Ye mitti bigaadte hain, praakritik shikaari aur pollinators ghataate hain, aur keeton ko pratirodhi banaate hain.
