Kodi biosphere ndi technosphere ndi chiyani amasangalatsa anthu ambiri. Komabe, kuti musasokonezeke ndikumvetsetsa chilichonse mwatsatanetsatane, muyenera kutanthauzira mawu aliwonsewo.
Zachilengedwe ndi chipolopolo cha Dziko Lapansi, lokhala ndi zamoyo ndikusinthidwa ndi iwo. Ndi chopereka cha zamoyo zonse. Biosphere ili ndi mitundu yoposa 3 miliyoni ya zomera, nyama, bowa ndi mabakiteriya.
Ndikofunikira kudziwa kuti munthuyo alinso gawo lake. Ndizosangalatsa kudziwa kuti chilengedwe padziko lapansi chitha kukhalapo popanda technosphere, pomwe chachiwiri popanda choyambirira sichitha.
Technosphere ndi zonse zomwe zachitidwa ndi umunthu. Ndiye kuti, chipolopolo chapadera cha dziko lapansi momwe zimachitikira zochita za munthu. Technosphere imaphatikizapo mabizinesi osiyanasiyana, nyumba, madamu, minda ndi zinthu zina zambiri. Nthawi zina amatchedwa "chilengedwe chachiwiri", chopangidwa ndi anthu kuti akwaniritse zolinga zawo, malingaliro awo kapena malingaliro. Masiku ano, technosphere ndi makina osapangidwira omwe amaphatikizapo malingaliro asayansi omwe cholinga chake ndikusintha dziko lapansi.
Makamaka m'zaka zaposachedwa, gawo la technosphere padziko lapansi lakhala likuwonjezeka kwambiri, pomwe gawo lachilengedwe likuchepa. Asayansi angapo akuti mtsogolomo chilengedwe chidzasinthidwa kwathunthu ndi chilengedwe cha techno, pomwe zinthu zonse zidzagwiritsidwanso ntchito ndikugwiritsidwanso ntchito kuti zisunge.
Kunena zowona, chilengedwe chimatanthauza zonse zomwe zidawoneka mwachilengedwe, ndipo ma technosphere amatanthauza chilichonse chopangira, ndiye kuti, chifukwa cha ntchito za anthu.
