Nguva mune geology haina kuyerwa mumakore, inoyerwa mumamirioni emakore. Aya anonzi maeon uye anonyanya kuzivikanwa geological epochs ndiPaleocene, Holocene, nezvimwe. Asi ikozvino, pari zvino, chero munhu akazvarwa muna 1950, ari kuzonzwa kunge akura zvakanyanya nekuti ivo vari kurarama maviri akasiyana mairi nguva.
Parizvino, mushure menguva yekupedzisira yechando, tinopinda muHolocene, asi takapihwa simba guru rine vanhu paPasi, yakapinda peji idzva mukarenda regeological, iyo Anthropocene.
Uchapupu hweanthropocene
Imwe yemiyedzo inoratidza kushanduka kwenzira yepasi redu iri chikepe cheBilbao. Iyo tambo yemamita manomwe-masimbi akaunganidzwa neindasitiri. Imwe nzira yekufunda nguva dzekare dzepasi ndeyekudzidza kuunganidzwa kwenzvimbo munhoroondo. Naizvo, Aya ma sediment emabhizimusi atove chikamu chehupenyu hwepasi.
Boka revasayendisiti avo vaitarisira kusarudza izvi vakabvumirana kutaura kuti takapfuura Holocene kupinda muAnthropocene. Tsoka dzezviitiko zvevanhu dzinozoiswa nekusingaperi mupasi rese seyakakurumbira mutsetse unozoonekwa zviuru kana mamirioni emakore kubva izvozvi mumapako nemawere, chirevo chenguva dzese kune vesaenzi venguva yemberi. Boka rakasarudzika revanyanzvi rakafunga izvo Anthropocene inotanga muna1950 nemarara ane mwaranzi kubva kumabhomba eatomiki.
Zviitwa zvedu zvachinja nyika
Nemabasa edu isu takachinja Nyika. Ino ndiyo nguva yatakakwanisa kushandura hupenyu hwepasi, tichiibvisa mukusiyana kwayo kwepanyama. Zvizhinji zvezvakatipoteredza, nzvimbo dzekugara, mhando dzese mhuka nezvirimwa, mabhakitiriya uye zvimwe zviri kuchinjika nekukudziridza kunzira yedu yehupenyu, pachinzvimbo chekuve chakapesana.
Chiratidzo chinokonzeresa kutanga kweiyi geological epoch marara ane radioactive eplutonium, mushure mekuyedzwa kwakawanda kwemabhomba eatomiki akaitwa pakati pezana ramakore rechi7. Iyo tambo yemamita angangoita XNUMX metres pakakwirira pavari zvisaririra zve slag yakaburitswa nemhepo yekufema pakati pa1902 na1995 inogona kuoneka pamhenderekedzo yesamende yeTunelboca.
Zvinodiwa kuti utore nyowani geological nhanho
Kuti utange kutanga kweiyo nyowani geological nhanho, panofanirwa kuve nechiratidzo chekuti, pasirese, chinowirirana shanduko dzese padanho repuraneti. Pakutanga, nyanzvi dzakafunga nezve gore 1800 sezuva rekutanga reAnthropocene, pamwe neindasitiri yekumukira. Zvisinei, yakaraswa nekuti tsoka yaro haiite zvakaenzana uye panguva imwechete kumativi ese epasi.
Chinhu chakakosha nezvenyaya iyi hachisi chekuti munhu akaita mucherechedzo wake. Izvi zvave zvichiitwa kwenguva yakareba, zviuru zvemakore kunyangwe. Iyo kiyi yekumisikidza nyowani geological nhanho ndeyekuti iko kutenderera shanduko mune hunhu hwepasi rese. Izvi zvinokonzerwa ne zviitiko zvedu zvevanhu, kusvibiswa kwedu, mapurasitiki edu, gasi rinokanganisa gasi, tsvina yemabhizimusi, shanduko yezvakatipoteredza, kunyangarika kukuru kwezvisikwa, acidification yemakungwa ... Mazhinji eshanduro idzi anogara kwenguva refu, uye mamwe haachinjiki.
Ndokusaka kutonga uku kwesainzi kwave kwakaringana kuratidza kutanga kweAnthropocene senge nyowani geological nhanho umo protagonist yeshanduko yezvakatipoteredza uye mumatunhu ePasi munhu. Uchapupu hunoratidza danho iri reAnthropocene huchagara papasi redu nekusingaperi.
Izvi zvinogadzira makakatanwa akasiyana siyana nezvekukundikana kwevanhu munharaunda yedu, kunyanya nekuuya kwekushanduka kwemamiriro ekunze. Izvo hazvigone kutongwa kuti chokwadi chekuti ma dinosaurs akatsakatika chaive chakanaka kana chakaipa, uye zvakadaro isu tanga tisipo uye kure nazvo, isu taive chikonzero chekutsakatika kwavo. Asi ikozvino nhasi, isu tine mhosva yekuchinja pano pasi. Ndokusaka kusahadzika kuchimuka nezve "kukosha" kwedu pasi rino. Tiri denda here kana chirwere kune mamwe marudzi ese?
