Ek Ulta Pyramid 🔺
Pichhle lesson mein humne dekha ki energy har level par ghatti jaati hai. Ab ek aisi cheez dekhte hain jo bilkul ulta karti hai — wo har level par badhti jaati hai.
Wo cheez hai zeher — khaaskar pesticide, aur kuch metals jaise paara (mercury) aur seesa (lead).
📌 Biomagnification (jaiv magnification) = kisi haanikaarak rasayan ka food chain mein upar jaate-jaate zyada se zyada gaadha (concentrated) hote jaana.
❓ Aisa hota kyun hai — do wajah:
1️⃣ Zeher tootta nahi. Khaana toh pach kar khatam ho jaata hai, par ye rasayan
shareer mein jama ho jaate hain (khaaskar charbi mein). Shareer unhe bahar nahi
nikaal paata.
2️⃣ Har jeev bahut saara khaata hai. Ek badi machhli apni zindagi mein
sainkdon chhoti machhli khaati hai — aur un sab ka zeher
usi ek mein jama ho jaata hai.
Nateeja: energy 10% reh jaati hai, par zeher 10 guna ho jaata hai.
Paani mein pesticide: 0.003 ppm (ppm = parts per million)
Plankton (level 1) = 0.003 ppm
Chhoti machhli (level 2) = 0.003 × 10 = 0.03 ppm
Badi machhli (level 3) = 0.03 × 10 = 0.3 ppm
Bagula (level 4) = 0.3 × 10 = 3 ppm
Kul badhotri = 3 ÷ 0.003 = 1000 guna!
⚠️ Aur dhyaan do — paani bilkul saaf lag raha tha. 0.003 ppm itna kam hai ki koi
jaanch bhi shayad na kare. Par sabse upar wale pakshi ke liye wo
jaanleva ban gaya.
👨👩👧 Aur Insaan Kahan Hai Is Chain Mein?
⚠️ Insaan lagbhag hamesha sabse UPAR hota hai.
Hum badi machhli khaate hain, murgi khaate hain, doodh peete hain — yani hum aksar
trophic level 3 ya 4 par hote hain.
Aur biomagnification ka niyam yahi kehta hai: jo sabse upar hai, uske shareer mein zeher
sabse zyada jama hoga.
Isiliye pesticide ka sabse bada khatra kheton mein kaam karne walon ko aur
hum sabko hai — chidiyon ko nahi.
🩺 Bachne ke aasaan tareeke:
🥬 Sabzi aur phal ko khoob achhe se dho kar khao — thodi der
namak ya haldi ke paani mein bhigo dena aur behtar hai
🍎 Jahan ho sake, chhilka utaar do
🐟 Bahut badi aur bahut purani machhli mein
paara (mercury) zyada hota hai
🌾 Jaivik (organic) ya sthaneey mausami sabzi behtar hai
⚠️ Aur sabse zaroori: pesticide sirf khaane se nahi, chhoone aur saans se bhi
andar jaata hai. Kheton mein chhidkaav karte waqt mask aur dastane pehanna
zaroori hai — bharat mein har saal hazaron kisan
pesticide poisoning ka shikaar hote hain.
1940-60 ke dashak mein DDT ko ek chamatkaari pesticide maana jaata tha. Usne
malaria ke machharon ko maar kar karodon jaanein bachayin — uske aavishkaarak ko
Nobel Prize tak mila.
Par kuch saal baad america mein log dekhne lage ki baaz aur ugle (eagles)
achanak khatam ho rahe hain. Wajah? DDT unke shareer mein biomagnification se jama ho gaya tha, aur
usse unke ande ke chhilke itne patle ho gaye ki maa ke baithte hi wo
toot jaate the.
1962 mein Rachel Carson ne apni kitaab "Silent Spring" mein likha ki ek
din aisi subah aayegi jab chidiyon ki awaaz hi nahi aayegi. Us kitaab ne poori
duniya ko hila diya.
Nateeja: kai deshon ne DDT par rok laga di, aur baaz ki ginti dheere-dheere
wapas aa gayi.
Sabak: koi rasayan "chamatkaar" lag sakta hai, par uska asar poore food chain par
dekhe bina uska istemaal khatarnaak hai.
Bharat mein Punjab ke kuch ilaakon ko dukh ke saath
"cancer belt" kaha jaata raha hai. Harit Kranti ke baad wahan
bahut zyada pesticide istemaal hua, jo mitti aur bhoojal (groundwater) mein
pahunch gaya — aur phir fasal aur logon tak.
Bathinda se Bikaner jaane wali train ko log
"cancer train" kehne lage the, kyunki usse bahut se mareez ilaaj ke liye jaate
the. (Vaigyanik iski poori wajah par abhi bhi adhyayan kar rahe hain, par pesticide ek badi chinta
zaroor hai.)
Isi wajah se aaj bharat mein kai khatarnaak pesticide pratibandhit kiye ja chuke
hain, aur jaivik kheti (organic farming) ko badhawa diya ja raha hai.
Sikkim 2016 mein duniya ka pehla poori tarah
jaivik rajya ban gaya — wahan rasayanik pesticide ka istemaal hi nahi hota.
Ye lesson sirf ek pyramid ka chitr nahi hai — ye seedha
aapki thaali se juda hua hai.
