Nemoš' izjednačiti rezultat ni za nekoliko milenija, jer u nas živi preko 40 000 vrsta i svakih nekoliko godina se otkrije na stotine novih. Tih 18 vrsta bi nestalo prije ili kasnije i bez čovjeka.
Citiranje Knjige Postanka me duboko dirnulo u srce ateističko. Evo suze lijem kad se sjetim tog dana.MmeTipfeler wrote: ↑10 Jun 2019, 08:11Ne. Antropocentrizam je ovo: »Načinimo čovjeka na svoju sliku, sebi slična, da bude gospodar ribama morskim, pticama nebeskim i stoci – svoj zemlji – i svim gmizavcima što puze po zemlji!«

Osamnaest je popisa, a ne vrsta. U Hrvatskoj godišnje izumru tri-četiri biljne i životinjske vrste, to je prosjek. Desetak vrsta nestane u samo tri godine, znači. Možda bi iščeznule same, možda bi ih istrijebio čovjek izravnim i neizravnim djelovanjem, no to ne znači da ti "matematika" štima. Otkrivanje nove vrste nikada ne znači da je posrijedi nešto što je nastalo jučer. Otkrivanje nove vrste znači da je posrijedi nešto što jučer nismo opazili. Ne shvaćam kako ti to nije jasno. Rezoniraš kao petogodišnjak.

Imaš pravo previdio sam to, a i nisam sam išao do kraja provjeravati te tvoje tvrdnje. Mea culpa.
Hrvatska je napravila 17 crvenih popisa i 10 crvenih knjiga. Barem sam ih ja toliko nabrojao na stranici Hrvatske agencije za okoliš i prirodu.
Evo što piše o tim dokumentima:
Također je zanimljivo što piše u Crvenoj knjizi vaskularne flore Hrvatske:

Evo što piše o tim dokumentima:
Crveni popis je dokument koji donosi informacije o riziku od izumiranja, razlozima ugroženosti te potrebnim mjerama očuvanja pojedinih divljih vrsta i staništa kojima je procijenjena ugroženost.
Ako odbijemo regionalno izumrle vrste (RE),onda imamo samo jednu izumrlu vrstu na području naše države. To je biljna vrsta Dianthus multinervis Vis. ilitiga Jabučni klinčić. Moguće je da sam koju propustio u brzini, pa me ispravite.Crvene knjige predstavljaju publikacije koje, uz razrađeni prikaz informacija iz crvenih popisa, objedinjuju i dodatne podatke o vrstama i staništima kojima je procijenjena ugroženost (npr. opis, rasprostranjenost, biologija vrste). Cilj crvenih knjiga je podizanje razine znanja o ugroženim vrstama i staništima te osvještavanje javnosti o potrebi njihovog očuvanja
Također je zanimljivo što piše u Crvenoj knjizi vaskularne flore Hrvatske:
Naime, od g. 1600. do danas, pod izravnim ili posrednim utjecajem čovjeka zabilježen je nestanak 191 vrste mekušaca,
115 vrsta ptica, 58 vrsta sisavaca, 120 ostalih vrsta životinja, 654 biljne vrste (WCMC 1992)

Više ih je, spomenuo sam npr. potkovnjaka, sljepaša, droplju, starješinu, crkavicu, jesetrovke... Posljednji primjerak sredozemne medvjedice ubijen je 1964. pa ih u Jadranu nema, ali znaju zalutati iz Sredozemlja, gdje se još mogu naći.

Da, to su te regionalno izumrle vrste (RE). Nema ih više kod nas, ali nisu izumrle globalno gledajući.
Sve u svemu ugroženih vrsta ima, ali bajke o nekakvom šestom masovnom izumiranju su samo bajke za malu djecu.

Ni u jednome postu nisam to spomenuo, nemoj me miješati s drugim sugovornicima. Moja je perspektiva realna, govorim o tome da svaka biljna i životinjska vrsta ima u prirodi mjesto i funkciju. Istrijebiš li pčele, nema ti tko oprašivati floru. Nestanu li morski psi, nitko neće čistiti mora i oceane.
Sasvim je jasno da bez mnogih vrsta možemo, ništa se sudbonosno neće dogoditi ako izumru (osim što će određeno vrijeme biti poremećena biološka ravnoteža). Ali neke su strahovito bitne - i nenadoknadive.

Na popis vrsta za odstrel stavljam krpelje i komarce.

Živčenjak jedan obični. Baš su slatki. Ne dam ih.
96% mase svih sisavaca danas su ljudi i domestificirana stoka, čovječanstvo koristi 1,75 više prirodnih resursa nego što se stiže obnoviti, a vi blebećete o nekim smrdljivim martinima.

New findings suggest Earth may have crossed a major climate line
https://www.msn.com/en-xl/news/other/ne ... s-AA20k7Z3
In a study published in Nature Geoscience, researchers from Toho University in Japan used NASA planetary models and conducted 400,000 simulations. Their results suggest that Earth’s atmosphere could become unbreathable in roughly one billion years. The Earth has crossed the tipping point beyond which it can no longer sustain its oxygen levels in the long term, triggering an irreversible atmospheric decline driven by increased solar luminosity.
With a history of about 4.5 billion years, Earth is approximately halfway through its estimated lifespan and, according to multiple astrophysical studies, could extend for another 5 billion years. However, its future is closely linked to the Sun's evolution, whose brightness increases slowly at about 1% every 100 million years.
The Sun has been shining for about 4.6 billion years. In its core, where fusion is most intense, much of the hydrogen has been transformed into helium, which remains there and absorbs radiation more readily than hydrogen, raising the core temperature and increasing its luminosity, according to Britannica. When the Sun exhausts the hydrogen in its core, fusion will shift to the outer layers, progressively increasing its luminosity. Eventually, it will enter a red giant phase and expand until it reaches the orbit of Venus or even Earth, although this process will take billions of years.
The research, a collaboration between NASA and Toho University in Japan, covers scenarios that have enabled scientists to project the long-term fate of Earth, analyzing variables such as solar luminosity, atmospheric composition, and biogeochemical activity. Scientists estimate that the gradual increase in the sun's brightness will trigger an uncontrolled greenhouse effect, according to El Tiempo. As the sun increases its luminosity, the oceans will begin to evaporate massively. This water vapor, a potent greenhouse gas, will intensify global warming by trapping more heat in the atmosphere. This effect will accelerate an irreversible feedback loop called the "runaway greenhouse effect" due to the complete evaporation of the oceans, which will turn Earth into an environment incompatible with life as we know it, according to Wikipedia.
Nije tako kritično kako na prvi pogled izgleda, za milijardu godina nećemo moći disati — ako preživimo dotad kao vrsta. Šanse su male, ali ja sam po prirodi optimist.
