Video clips nrog cov tsiaj uas raug ntes hauv cov pob khoom cellophane zoo ib yam yog qhov txaus ntshai - neeg xiam oob khab, raug tsim txom kom tuag los ntawm yas captivity vim tib neeg tsis saib xyuas. Thiab ntau npaum li cas ntawm cov khib nyiab no tsuas yog dag nyob ib ncig ntawm lub ntiaj teb, ua rau muaj kev puas tsuaj rau txhua yam muaj sia, ob qho tib si mechanically thiab chemically. Tsis ntev los no, lub tswv yim hais tias lub hnab biodegradable yog ib txoj hauv kev tawm ntawm qhov kev puas tsuaj ntawm ecological kev puas tsuaj tau nthuav dav.
Sustainability of life
hnab yas yog qhov ntau tshaj plaws, tsis pom tseeb, tab sis cov khoom tsim nyog hauv tsev. Cov neeg yuav lawv xyaum hauv cov pob khoom - txhua qhov kev yuav khoom, ib yam khoom hauv lub txee dai khaub ncaws, khoom noj khoom haus rau kev ua haujlwm lossis tsev kawm ntawv - txhua yam yog qhwv hauv cov yas, kom nws thiaj li muab pov rau hauv lub thoob khib nyiab ze tshaj plaws lossis hauv qab koj txhais taw. Nws yog qhov zoo thaum cov khoom pov tseg hauv tsev tau muab pov tseg raws li tag nrho cov cai, thiab tsis litter tag nrho qhov chaw nyob ib puag ncig. Tab sis txawm nyob rau hauv tshwj xeeb landfills, yas thiab polyethylene yog ib qho teeb meem loj. Cov ntaub ntawv no siv sij hawm ntev heev kom decompose tias thaum lub sij hawm txheej txheem lawv tswj kom lom lub ntiaj teb nyob ib ncig ntawm lawv nrog cov khoom lwj.
Environmentalists thiab chemists tau npaj los daws qhov teeb meem los ntawm kev tsim lub hnab biodegradable. Lub ntim ntawm ib yam khoom yuav tsum muab pov tseg ntawm tag nrho covtxoj cai, thiab yog tias tsis tso cai rau rov siv dua, ces nws yuav tsum yaj nyob rau hauv lub ntiaj teb sab nraud yam tsis muaj kev puas tsuaj rau nws. Yog li ntawd, kev tsim cov hnab biodegradable, xav tias, yog lub neej yav tom ntej ntawm ecology.
Ntawm qhov tshiab
Cov chaw tsim khoom ntawm lub hnab biodegradable, thiab twb muaj ob peb ntawm lawv nyob ib ncig ntawm lub ntiaj teb no, ib txwm qhia ntawm lub ntim khoom yam khoom no yog ua los ntawm. Zoo, thaum lub hnab yog ntawv - tsis muaj lamination thiab ntau ntawm hluavtaws dyes, nws yuav tsuas yaj nyob rau hauv cov xwm, rov qab yuav luag rau nws thawj lub xeev. Tab sis yog hais tias muaj pes tsawg leeg ntawm cov khoom ntim muaj cov tshuaj sib xyaw ua ke, ces qhov no tsis yog ib qho khoom zoo rau ib puag ncig. Txawm hais tias, txhawm rau ua kom lub hnab biodegradable, cov khoom tshwj xeeb yuav tsum tau ntxiv rau hauv cov khoom sib xyaw kom pab cov khoom tawg mus rau hauv cov khoom yooj yim.
Tej zaum koj yuav xav tias cov pob khoom zoo li no tsis tuaj yeem yuav rau yav tom ntej, tias tom qab pw hauv tsev hauv "pob nrog pob", lawv yuav tig mus ua hmoov av, haum rau kev pov tseg. Tab sis nws tsis yog. Raws li feem ntau manufacturers ntawm biodegradable hnab, lawv khaws lawv cov khoom lag luam rau 3 xyoos. Zoo, ib zaug nyob rau hauv "zoo" tej yam kev mob nyob rau hauv lub hnub lub rays nyob rau hauv qhib huab cua, nyob rau hauv lub zog ntawm cua, los nag, txias, xws li siv ntim hloov mus rau hauv tej yam ntuj tso Cheebtsam tom qab ob peb lub hlis.
tseeb los yog cuav?
Niaj hnub tsim cov hnab yas biodegradable yog yav tom ntej ntawm kev txuagnatural resources thiab ecology. Tab sis qhov no tsuas yog siv rau cov hnab ntuj tsim los ntawm cov khoom siv los ntawm cov qos yaj ywm thiab pob kws hmoov txhuv nplej siab, cane, thiab cov khoom noj siv mis. Muaj kev xav tias cov pob khoom zoo li no yooj yim heev - tsis muaj dab tsi tuaj yeem hloov mus rau lawv. Tab sis qhov no tsis yog qhov teeb meem, cov pob khoom sib raug rau lub peev xwm thauj khoom tau tshaj tawm los ntawm cov chaw tsim khoom, uas tau qhia rau ntawm lub ntim nrog cov pob lossis ntawm txhua pob sib cais.
Tab sis tsuas yog lub hnab ntuj lossis ntim khoom tuaj yeem hu ua biodegradable. Yog hais tias lub thawv pov tseg crumbles rau hauv microplastics dhau sijhawm, nws tuaj yeem hu ua biodegradable nrog lub stretcher. Raws li ntau tus kws tshawb fawb, cov pov tseg pov tseg ntawm cov ntim zoo li no kuj tsim kev puas tsuaj rau txhua yam muaj sia. Qhov no yog qhov tseeb tshwj xeeb ntawm cov neeg nyob hauv qab dej uas noj cov granules me me, ua rau lawv yuam kev rau plankton lossis qee cov crustaceans. Yog li nws yog qhov nyuaj heev los tham txog kev nyab xeeb ntawm cov khoom siv zoo li no. Nws yog qhov duality ntawm lo lus "lub hnab biodegradable" uas hais txog kev dag ntxias cov neeg siv khoom.
Nqe
Rau ntau tus neeg tam sim no, cov teeb meem ntawm kev txuag tseem ceeb dua li cov teeb meem ntawm ecology. Tom qab tag nrho, zoo li ecology yog ib yam dab tsi ephemeral, uas "tsis cuam tshuam rau kuv", tab sis txuag tsev neeg cov nyiaj txiag, tshwj xeeb tshaj yog nyob rau hauv tsev neeg trifles, yog ib qho tseem ceeb. Tab sis nws yog qhov opposite.
Ecological kev ruaj ntseg ntawm lub ntiaj teb uas txhua tus tsiaj nyob yog lub hauv paus ntawm lub neej yav tom ntej. Tab sis tsev neeg trifles uas tuaj yeem ua kom lub ntiaj teb ntau dua lossis tsawg dua tus nqi huv me ntsis ntau dua li covuas ua phem rau lub ntiaj teb nyob ib puag ncig peb rau 100, 300, 500, lossis ntau txhiab xyoo tom ntej. Tom qab tag nrho, ib lub hnab yas zoo tib yam, uas nyob rau hauv ib lub khw muag khoom yog ib qho yooj yim thiab siv tau ntim rau ib qho kev yuav khoom, yuav tig mus rau hauv cov tshuaj yooj yim sib txuas rau ntau tshaj ib puas xyoo, uas tsis muaj peev xwm ua phem rau lub ntiaj teb, dej, thiab cov tsiaj nyob ze. Thiab lub ntim, uas yog tsim los ntawm cov khoom xyaw ntuj, raug nqi me ntsis - 5-10% ntau dua li cov nqi ib txwm muaj ntawm cov khoom me me. Yog li lub pob zeb biodegradable tiag tiag tsis yog tuaj yeem txuag tau nyiaj txiag xwb. Nws tseem tuaj yeem cawm lub ntiaj teb los ntawm kev puas tsuaj ib puag ncig.
Kev tsim cov khoom siv biodegradable rau tsev neeg siv, suav nrog cov hnab ntim khoom, yuav txo qhov kev puas tsuaj uas tib neeg ua rau xwm txheej.
