Zachilengedwe, chipolopolo chapamwamba cha Dziko Lapansi, momwe zinthu zonse zamoyo zimakhalapo, ndizachilengedwe padziko lapansi. Amakhala ndi hydrosphere, m'munsi m'mlengalenga, ndi kumtunda lithosphere. Palibe malire omveka bwino azachilengedwe, nthawi zonse amakula bwino.
Kuyambira nthawi yomwe munthu adawoneka, ayenera kulankhula za chinthu chomwe chimakhudza chilengedwe. M'nthawi yathu ino, kuthamanga kwa izi kukukulira makamaka. Nazi zitsanzo zochepa chabe za zochita za anthu zomwe zimawononga chilengedwe: kuchepa kwa zinthu zachilengedwe, kuwonongeka kwa chilengedwe, kugwiritsa ntchito matekinoloje aposachedwa kwambiri osatetezeka, komanso kuchuluka kwa anthu padziko lapansi. Chifukwa chake, munthu amatha kusintha kwambiri zinthu zachilengedwe padziko lonse lapansi ndikuzipangitsa kukhala pachiwopsezo.
Mavuto azachitetezo cha chilengedwe
Tsopano tiyeni tikambirane zamavuto achitetezo cha chilengedwe. Popeza zochitika zaumunthu zimawopseza chipolopolo chamoyo padziko lapansi, mphamvu ya anthropogenic imabweretsa kuwonongeka kwa zachilengedwe ndi kuwonongeka kwa mitundu ya zomera ndi zinyama, kusintha kwa kupumula kwa kutumphuka kwa dziko lapansi ndi nyengo. Zotsatira zake, ming'alu ya lithosphere ndi mipata mu biosphere imapangidwa. Kuphatikiza apo, chilengedwe chimatha kudzipweteketsa: mapiri ataphulika, kuchuluka kwa mpweya woipa m'mlengalenga kumawonjezeka, zivomezi zimasinthanso, moto ndi kusefukira kwamadzi kumabweretsa kuwonongeka kwa mitundu yazomera ndi nyama.
Kuti tisunge zachilengedwe zapadziko lonse lapansi, munthu ayenera kudziwa zavuto la kuwonongeka kwa chilengedwe ndikukhala mbali ziwiri. Popeza vutoli ndilopadziko lonse lapansi, liyenera kuthana ndi boma, chifukwa chake likhale ndi malamulo. Maiko amakono amapanga ndikukhazikitsa mfundo zomwe zingathetse mavuto apadziko lonse lapansi. Kuphatikiza apo, munthu aliyense atha kuchita nawo izi: kuteteza zachilengedwe ndikuzigwiritsa ntchito moyenera, kutaya zinyalala ndikugwiritsa ntchito matekinoloje opulumutsa zida.
Kupanga madera otetezedwa ngati njira yosungira chilengedwe
Tikudziwa kale mavuto omwe dziko lathuli lili nawo, komanso chifukwa cha zolakwika za anthu omwe. Ndipo ili si vuto la omwe adatsogola, koma mibadwo yapano, popeza chiwonongeko chachikulu chidayamba kuchitika m'zaka za zana la makumi awiri ndi kugwiritsa ntchito matekinoloje anzeru. Vuto losunga Dziko Lapansi lidayamba kukwezedwa pagulu posachedwa, koma, ngakhale ali wachinyamata, mavuto azachilengedwe amakopa anthu ochulukirachulukira, pakati pawo pali omenyera enieni zachilengedwe ndi zachilengedwe.
Pofuna kusintha mwanjira zachilengedwe ndikusunga zachilengedwe zina, ndizotheka kupanga malo osungirako zachilengedwe ndi malo osungirako zachilengedwe. Amateteza chilengedwe mwanjira yoyambirira, ndikoletsedwa kudula mitengo mwachisawawa ndikusaka nyama m'malo otetezedwa. Chitetezo cha zinthu zotere komanso chitetezo cha chilengedwe chimaperekedwa ndi mayiko omwe ali pamtunda wawo.
Malo osungira nyama zakutchire kapena paki yachilengedwe ndi malo achilengedwe momwe mitundu yonse yazomera zakomweko imakula momasuka. Izi ndizofunikira makamaka pakusunga mitundu yambewu yosowa. Nyama zimayenda mozungulira malowa momasuka. Amakhala monga adakhalira kuthengo. Nthawi yomweyo, anthu amachita zochepa:
- kuyang'anira kuchuluka kwa anthu komanso ubale wa anthu;
- kuchiza nyama zovulala ndi zodwala;
- munthawi zovuta, ponyani chakudya;
- tetezani nyama kwa achiwembu omwe amalowa mderalo mosaloledwa.
Kuphatikiza apo, alendo komanso alendo paki ali ndi mwayi wowonera nyama zosiyanasiyana patali. Zimathandiza kubweretsa anthu ndi zachilengedwe pafupi. Ndibwino kubweretsa ana kumalo amenewa kuti akalimbikitse kukonda chilengedwe ndikuwaphunzitsa kuti sichiwonongeka. Zotsatira zake, zomera ndi zinyama zimasungidwa m'mapaki ndi malo osungirako zinthu, ndipo popeza palibe zochitika za anthropogenic, palibe kuipitsa chilengedwe.
