Pasina kumbobvira paine vanhu vanopfuura zviuru makumi maviri nevatatu vari kurarama munzira imwe chete yeNil, uye mazuva ano vanhu vanosvika mamiriyoni gumi nemana vari kugara pamwechete. Humanity yakapfuura 8 bhiriyoni vanhu mu 2022 uye United Nations inotarisira kuti huwandu hwevanhu hwasvika pakureba 10.3 billion mumid-2080s mushure mekuderera zvishoma nezvishoma. Maitiro ekuti vanhu vazhinji vanogona kurarama zvakanaka panzvimbo imwe chete, nenzvimbo, mhepo yakachena, maruva uye nzvimbo dzakasvibira dzakawanikwa, ndeimwe yematambudziko akakosha ezana ramakore. Iyi explaner ndeyekudzidzisa. Tinoona nezvekuremekedza sarudzo dzese dzemhuri; zvatinopikisa ndezvedzidzo, hutano uye sarudzo dzakanaka kune vese.

One simple equation

Vaongorori vanotaura kuti mhedzisiro yevanhu inoratidzwa nechiratidzo chikuru: Impact = Population x Affluence x Technology, kana kuti IPAT. Hupenyu hwevanhu hunoratidza kuti vanhu vanogara sei. Affluence ndiyo kuti munhu wose anodya sei. Technology ndiyo kuti sei kukonzera mhedzisiro yese yekushandiswa kwechigadzirwa: emissions pakilowatt-hour, nyika patone yekudya, uye zvicherwa pazvigadzirwa. Hachisi pamutemo wezvisikwa, asi chinoratidza kuti masimba aya ari kupi, uye kuti ese matatu akakosha.

Kukura kwevanhu kuri kunonoka munzvimbo dzakawanda, nekuti vabereki vari kusarudza kuva nevana vashoma sezvo kurarama kwevana, kudzidza (kunyanya kwevakadzi), uye mari dzichiwedzera. Makumi mana nemakumi masere enyika pasi rose ane huwandu hwevana hwaisvika 2.1 vana pamukadzi, izvo zviri pasi pehuwandu hwevana hunodiwa kuti nyika irambe ichikura. Kukura kwevanhu kunotarisirwa kuitika muAfrica neAsia; kunze uko vanhu vari kurarama makore akawanda uye munyika dzakawanda, vanhu vari kushaya hupenyu.

A: zvakadii kuti mumwe nemumwe wedu anoshandisa

Nhamba chete hadziiti chokwadi, nekuti munhu ari munyika ine mari anoshandisa nyika zvakanyanya kupfuura munhu ari munyika yakaipa. Kana vese vakagara semugari weUnited States, vanhu vanofanira kunge vachida nezve Zvitatu; sezvaanoita munhu anogara muIndia, anenge manomwe nemana ezana (Global Footprint Network). Iyo yakakura kwazvo yegumi yevanhu inonyanya kukonzera mamirioni makumi maviri nemana ezviuru zvemafuta, nepo iyo yakaderera kwazvo yegumi ichikonzera zviuru gumi nezviviri zvemamiriyoni.Chancel, 2022).

Izvi ndizvo zvinoita kuti kuwedzera kwevanhu munyika dzakakura kuite sekunge kuri kukuvadza mamiriro ekunze. Nekuti panzvimbo dziri kubudirira, zvose zvinoumba nzvimbo huru yevanhu, uye nyika inotora nguva yakareba kuti iite basa iri. The UN’s global biodiversity assessment ranks changes in land and sea use as the biggest direct driver of nature’s decline: three quarters of the land surface has been significantly altered by people, and around one million species are threatened with extinction (IPBES, 2019). Muchidimbu, matambudziko aya haasi kugadziriswa munguva pfupi: mhando yezvisikwa yakafa haizodzokerezve, uye michero yakare kana nzvimbo ine matombo anotora makore kuti idzokere, kana kuti inotora nguva yakareba.

Iyo nyika inotora kupfuura 100 billion tons yezvinhu pagore, katatu kupfuura mu1970 (UNEP International Resource Panel, 2024).

Iyo nyika yechitsuwa idiki: nharaunda yayo, masango, madziva uye mishonga ndeyese ine, uye hapana nzvimbo yekuenda. Izvi zvinoita kuti maguta aite sezvikoro zvedu zvekudzidza nezvezvakaitika kana dambudziko richikwira kupfuura zvarinogona kugadziriswa nenyika. Vadzidzisawo kutenda, nekuti nyaya inonyanya kufarirwa haisi chaizvoizvo zvayakaita.

Rapa Nui (Island yeEaster) inowanzotaurwa sechiratidzo: vanhu vemuIsland vakatora maruva ese kuti vatore zvifananidzo zvavo zvakaoma, uye nharaunda yavo yakaparadza. Collapse (2005) yaJared Diamond yakaita kuti iyi account izivikanwe. Musango wakanga wadzokera. Asi tsvakurudzo kubva pakutanga inotaura kuti nyaya iyi yaive yakaoma. Vanhu vanoonekwa sekunge vakasvika gare gare kupfuura zvaifungidzirwa, pamusoro 1200 (Hunt naLipo, 2006). Polynesian rats kuti vakauya navo akadya palm seeds uye akaderedza nharaunda rekukura (Hunt naLipo, 2009). Radiocarbon modeling inoti vanhu vakawedzera zvakasimba kusvika vaEuropean vakasvika mu1722 kupfuura kudonha pamberi pavo (DiNapoli et al., 2021), uye nzvimbo dzechikepe dzechitsuwa dzinogona kubereka vanhu vanopfuura zviuru zviviri (Davis et al., 2024). Vamwe vatsvakurudzi vanoramba vachiona kumanikidzwa kwekunze uye kwezvinhu mubhuku (Lima et al., 2020). Chii chisina chokwadi ndechekuti chii chakauya mushure mekusangana: mu1862 ne1863 vatambi vezvitendero vakatora vanhu vanodarika 1,400 kuPeru, chirwere chatevera, uye muna 1870s chete maererano ne111 islanders akapfuura.

Zvitsuwa zvizhinji zvinopa chokwadi chakasimba chekuti vanhu vari kubvisa nyika yavo. PaMangareva, kubvisa masango pazvikomo kwakakonzera kuora kwevhu, kupera kwezvirimwa zvemaruva uye zviyo zvekufambisa kano, pamwe nenguva refu yekurwara (Kirch, 1997). Neshamwari yake Henderson Island yakarasikirwa nemhando dzakasiyana dzezvipfuwo nekuda kwekuhwa uye yakanga yagara isina vanhu mushure mekunge kutengesa kwaiita kuti irambe ichishanda kushaya (Weisler, 1995). Pa Nauru, a century of phosphate mining for farms abroad has left the central plateau, about four fifths of the island, largely mined out and uninhabitable (Republic of Nauru, NBSAP). Uye Norse Greenland inoratidza kuti sei kumanikidzwa kwezvipfuyo zvakaomarara zvakabatanidzwa nekumhanyisa kwekunze (Zhao et al., 2022) uye kushungurudzika kwekutengesa ivory kunosiya makumi mana emakore ekugara.

Zvitsuwa zvinofa neimwe nzira chete. Asi apo nyika yakanga yashandiswa zvakawandisa, chero chimwe chikonzero chakafanana chakaita kuti zvive nyore kurarama.

A توازن, not a race

Hapana cheizvi zvinoreva kuti vanhu ndivo dambudziko. Izvi zvinoreva kuti zvinhu zvinoda kunyatsoenzaniswa: vanhu vari munharaunda iyo nyika, madziro uye ecosystems inogona kubatsira zvakanaka, nenzvimbo yekugara yezvisikwa uye yepamusoro-soro yekurarama kwese. Panyika yose, sezvavanhu vachiva nehutano hwakanaka, vadzidzira zvakanaka uye vari kuchengeteka, mhuri dzinosarudza kuva nevana vashoma, uye huwandu hwevanhu hunoramba huripo.

Izvi zvinounza mibvunzo inoita kuti tifunge nezvekutarisira hupenyu hwedu: vanhu vakachengeteka vanenge vasingabereki vachave nemakore akawanda. Tinoda kuti makore aya anenge achiwedzera ave nehutano, aite basa uye aite zvinhu zvakasiyana-siyana, kuitira kuti vanhu vane dzidzo yepamusoro varambe vachidzidza uye vachishanda kwenguva yakareba.

Chimwe chezvinhu zvinokosha zvikuru kuti vanhu vawane hutano hwakanaka ndechekudzidza, kunyanya kune avo vanenge vasina kukwanisa kuenda kuchikoro. Girls who stay in school tend to marry later, have children later, and have fewer and healthier children, by their own choice. World Bank inofungidzira kuti kudzidza kwevanakomana kunodhura nyika pakati pemadhora zviuru makumi maviri nemana nemakumi mashanu neshanu nemakumi masere nematatu emadhora. $15 and $30 trillion in lost lifetime earnings, and that universal secondary education for girls could reduce fertility and slow population growth (Wodon et al., 2018).
