M'zaka za zana la makumi awiri mphambu chimodzi, vuto lachitetezo cha chilengedwe likuwonjezeka. Njira yolinganizira bwino imafuna amalonda kuti azisamalira kwambiri zinyalala. Kusunga zachilengedwe moyenera ndikofunikira pachitukuko, popeza moyo wa anthu mwachindunji umadalira mtundu wazachilengedwe. Kupezeka kwa madzi akumwa, chonde chochuluka cha dothi, chakudya chokwanira ndi mavitamini ofunikira komanso ma microelements, monga mukudziwa, kuwonjezera pazomwe zimakhudza munthu wamakono, zimakhudza thanzi la mibadwo yamtsogolo.
Nkhani zazikulu zachilengedwe
Zachilengedwe, kupatula magawo ang'onoang'ono, ndizotheka kutengera kukhudzidwa kwa anthu tsiku ndi tsiku. Chidziwitso cha anthropogenic chimathandizira kusokonekera kwazinthu zachilengedwe ndikusokonekera kwa maunyolo azakudya chifukwa chakubala kwanyama kwa nyama zakutchire mozindikira.
Nkhani zazikulu zachitetezo cha chilengedwe zomwe zimakhudzana ndi gawo la nthaka ndi izi:
- kudula mitengo mwachisawawa;
- kugwiritsa ntchito mopanda nzeru malo odyetserako ziweto ndi msipu;
- kusowa kwa feteleza woyenera;
- kusakwanira kukonzanso nthaka mukakolola.
Kuti minda izitulutsa bwino, m'pofunika kusankha malo oyenera amtundu uliwonse wazomera, kudzala mitengo yokwanira, komanso kuchepetsa kuchuluka kwa ziphe zomwe zagwiritsidwa ntchito. Popeza ndizovuta kukonzanso nkhalango, ndikofunikira kusamalira kuchepa kwa nkhalango komwe kulipo kale.
Chofunikanso masiku ano ndi vuto la kutaya zinyalala:
- mabotolo apulasitiki ndi chimodzi mwazinthu zowononga kwambiri, chifukwa palibe tizilombo m'chilengedwe chomwe chitha kuwononga pulasitiki;
- matumba a cellophane - akugwera pansi, amapanga zinthu mozungulira zomera zomwe zilibe kanthu kuti zikule;
- mabatire, zida zamaofesi, zida zamakompyuta - zimakhala ndi zinthu zamagetsi ndi chindapusa chomwe chimafunikira kuyesayesa kwina kuchokera kwa ogwira ntchito m'mabizinesi ena.
Kupanga kwa zinthu zopangidwa ndi munthu sikunawonedwe mwachilengedwe. Ndi munthu yekhayo amene amatha kutaya zinyalala zoterezi. Njira yolondola kwambiri ndikubwezeretsanso pulasitiki mukatha kuigwiritsa ntchito popanga zinthu zatsopano zomwe ndizofunikira pazochitika za tsiku ndi tsiku.
Nanga bwanji za jini la padziko lapansi?
Ngati mavuto omwe ali pamwambapa akuphatikiza kuthekera kochira pakukhudzidwa kwanthawi yayitali m'chilengedwe, ndiye kuti malo opweteka otsatirawa azachilengedwe sangasinthe.
Kusintha kapangidwe kazachilengedwe ndi vuto lovuta lomwe nthawi zambiri silimafotokozedwa mokweza:
- Pakakhala kusintha kwa momwe mvula imagwirira mbali ya acidic, mvula yomwe imapereka mvula yothirira nthaka imakhala chinthu chowopsa. Mpweya wamadzimadzi umasokoneza zamoyo zonse, ndipo sulfure dioxide yopangidwa kuchokera ku mafuta, mafuta, palafini ndi mafuta, chifukwa cha kuwonjezeka kwa kawopsedwe, zimawononga kwambiri dziko lathu.
- "Zowonjezera kutentha" kumabweretsa kutentha kwanyengo, zomwe zimakhudza kwambiri moyo wa anthu. Mabowo a Ozone amatsogolera ku dzuwa ku biosphere, lomwe pang'onopang'ono koma mopweteka limawononga zamoyo zonse. M'mlengalenga, kuchuluka kwa kaboni dayokisaidi kumawonjezeka, zomwe zimapangitsa kuti mpweya uzizizira pang'onopang'ono.
Dziko lapansi likucheperachepera madzi. Zanyengo zimasintha, mawonekedwe achilengedwe amayamba kuchepa, kuwonongeka kumachitika m'ntchito yama cell osiyanasiyana amoyo.
Chitetezo cha chilengedwe ndi chiyani
Pofuna kupulumutsa dziko lapansi ku zisonkhezero zoipa za zinthu zosafunikira, nthambi yonse yazachilengedwe idasankhidwa. Boma lililonse lili ndi njira zoyendetsera zinyalala, zomwe zimaphwanya malamulo. Biotechnology yachilengedwe imagwira nawo ntchito posonkhanitsa, mayendedwe, kukonza ndi kutsatsa. Laboratories amalima mitundu yonse yazinthu zazing'ono zomwe zimatha kukonza zinthu zachilengedwe. Zinthu zopangidwa ndizopangidwa zomwe zimaphwanya pulasitiki ndi zinthu zina zopangira. Zambiri pazokhudza mfundo zamafakitale zimaphatikizaponso mbali zaukadaulo wopanga zachilengedwe womwe cholinga chake ndi kuthana ndi zovuta zomwe zimapangidwa ndi zinthu zopangira.
