Vuto lalikulu lazachilengedwe m'nthawi yathu ino ndikuwononga chilengedwe.
Mitundu ya kuipitsa mankhwala
- zoyipitsa - zoyipitsa zamankhwala zimapangidwa chifukwa cha chilengedwe ndi njira za anthropogenic;
- yachiwiri - imachitika chifukwa chakuthupi ndi mankhwala.
Anthu akhala akusamalira kuteteza zachilengedwe kwazaka zambiri, kuphatikiza mayiko otukuka apadziko lonse lapansi akuchita mapulogalamu aboma otukula chilengedwe. Kuphatikiza apo, mkhalidwe wakuipitsa mankhwala m'malo osiyanasiyana umasiyana mwamphamvu.
Anthu amakumana ndi zopangira zamankhwala m'moyo watsiku ndi tsiku komanso pogwira ntchito m'makampani ogulitsa mafakitale. Pankhaniyi, muyenera kugwiritsa ntchito mosamala ufa, zotsukira ndi zotsukira, ma bleach, zowonjezera zakudya ndi ena.
Zosiyanasiyana za kuipitsa mankhwala
Mwanjira imodzi kapena ina, m'thupi la zinthu zosiyanasiyana zamoyo, pali zinthu zamagulu ang'onoang'ono. Thupi limathandiza pa zinc, calcium, iron, magnesium, ndi zina zambiri.
Kuwononga mankhwala kumakhudza magawo osiyanasiyana a chilengedwe, chifukwa chake kuli koyenera kuwunikira mitundu yotsatirayi ya kuipitsa:
- mumlengalenga - kuwonongeka kwa mpweya m'mizinda ndi mafakitale;
- kuipitsa nyumba, nyumba, nyumba zogona ndi mafakitale;
- kuipitsidwa ndikusintha kwa zakudya ndi zowonjezera zamagetsi;
- Kuwononga kwa hydrosphere - madzi apansi ndi madzi apansi, chifukwa chake, omwe amalowa m'mapaipi amadzi, amagwiritsidwa ntchito ngati kumwa;
- Kuwonongeka kwa lithosphere - panthawi yolima nthaka ndi agrochemistry.
Kuwononga kwa mankhwala padziko lapansi ndikotsika pang'ono kuposa mitundu ina ya kuipitsa, koma kumawonongetsanso anthu, nyama, zomera ndi zamoyo zonse. Kulamulira ndi kugwiritsa ntchito mankhwala moyenera kumathandizira kuchepetsa kuopsa kwa vutoli.
