Kooda alag kyun? Jeevon ka kaam aur dher ki samasya
Ek hi thaili mein chhilke, plastic aur kaagaz daalna 'bas ek chhoti si sustee' lagti hai. Is chhoti sustee ka poore shehar par kya asar padta hai?
Socho pehle… phir dekho jawab
Chhilke jaise jaivik padarth bacteria aur fungi dwara tootkar khaad ban sakte hain, par plastic nahi. Mila-jula kooda kooda-maidan (landfill) mein dab jaata hai, jahan khaad ki jagah sadan aur badbu hoti hai, aur recycle hone wali cheezein bhi kharab ho jaati hain.
Neha ki society mein safai karmi Raju bhaiya roz mila-jula kooda haath se alag karte the. Neha ne society ki meeting mein sujhaav rakha: har ghar mein do dibbe. Us hafte se Raju bhaiya ka kaam aasaan ho gaya aur society ki khaad bhi banne lagi.
Biodegradable woh hai jise jeev tod sakte hain (chhilke, patte, kaagaz). Non-biodegradable (zyadatar plastic, kaanch, dhaatu) ko jeev nahi todte; yeh saalon tak bachte hain. Isliye kooda source par hi alag karte hain: geela, sookha, aur ghar ka khatarnak kooda (jaise purani battery, tube-light, dawai). Khatarnak kooda kabhi mat chhuo, bade ko do.
Kooda-maidan ki samasya: jagah ghirti hai, badbu aur makkhi-machhar badhte hain, aur baarish ka paani kooda se guzar kar zameen ke paani ko gande kar sakta hai. Isliye 3R: Reduce, Reuse, Recycle.
Ghar pe try karo
3 din ka 'kooda-log' banao: ghar mein do tokri rakho (bade ki madad se). Roz raat ko dono ki cheezein ginke table mein likho. Ek cheez chuno jo kam ki ja sakti hai (Reduce) aur ek jo dobara kaam aa sakti hai (Reuse). Kaanch, tooti cheez, dawai aur battery ko haath mat lagao.
Wow!
Sabzi ke chhilke aur patte sahi tareeke se rakhe jaayein toh woh dobara mitti ka hissa ban jaate hain — kooda khazana ban sakta hai!
3 sawaal
- Kaun sa kooda biodegradable hai?
Jawab dekho
Sabzi ke chhilke. Chhilke bacteria aur fungi dwara toot kar khaad ban jaate hain.
- Purani battery ya tube-light ka kya karein?
Jawab dekho
Bade ko batayein aur alag rakhwayein. Yeh khatarnak kooda hai; ise haath nahi lagate, bade ko batakar alag rakhwate hain.
- Mila-jula kooda kooda-maidan mein kya samasya badhata hai?
Jawab dekho
Jagah ghirti hai, badbu aati hai aur paani gande ho sakte hain. Kooda-maidan mein jagah ghirti hai, badbu badhti hai aur gande paani se zameen ka paani kharab ho sakta hai.
