  1. It took hundreds of millions of years for cyanobacteria to "terraform" Earth. Do you wish to wait so long for terraforming other planets?

  2. I would. Birds are a superior life form

  3. I would be happy to see the day that human population will finally go down haha

  4. I was so intrigued by her when I first learned about her. Because I also had been always interested in knowledge and had wanted to be a scientist since childhood. I also found painting of her from when she was 15. She looked rather similar to me when I was the same age. I am very happy about it

  5. The drawing of her in thumbnail is really bad, just saying

  6. Bullshot right from the beginning: Russia's population is not declining anymore. Last 3 years it is slowly rising due to immigration and small natural growth

  7. I am a microbiologist, and I am not sure about this. Actually concentration of oxygen in ocean and athmosphere was rising very slowly after cyanobacteria started to produce oxygen. And microorganisms reproduce and thus evolve very fast (compared to macroorganisms), thus they probably had enough time to evolve and adapt to rising concentration of oxygen. Surely, some taxonomic groups went extinct, but most survived and adapted. "Almost wiped out life on Earth" is a ridiculous exaggeration.

  8. Everyone always values themselves and people they know personally most of all. But it is not a universal rule that people you don't know have to be valued more than non-human animals. In fact many people value animals they care for like pets more than some people they don't know

  9. Important thing that most of educational videos ignore : unoxygenic photosynthesis existed long before oxygenic. Many microorganisms could photosynthesize (and can) without producing oxygen, and that is simpler and older form of photosynthesis

  10. Japan's population pyramid is my favourite. I want the same in my country

  11. Also: not all cyanobacteria are unicellular. Many of them consist of trichoms - chains of cells, and some cells have specific functions like nitrogen fixing, reproduction etc. Those cyanibacteria are technically multicellular even though level of complexity is not as big as among multicellular eukaryotes.

  12. Lol exactly.

  14. I cannot edit when I use my phone

  15. Lets just leave as much land as we can alone, so the natural vegetation is restored by itself! That is better

  16. What are the criteria of "success"? Who decides on them? Why should I even accept them? What everyone else finds "successful" is not important to me

  17. What matters is how good people live while humanity exists, not how long it will exist

  18.  @tuna5305  their corporations would better benefit millions if they were transformed into worker co-ops with all millions of workers owning them collectively. And the billionaires would stop extracting so much value created by their employees' work. The wages would be bigger. So no, billionaires and their existence actually are not themselves a benefit to anyone else

  19. I love birbs so much, that I would forgive them everything. 😂😭

  20. The only way to not harm other living beings is never existing. But noone chooses to come into existence. But, we can choose whether to bring new people into existence. So you can minimise your bad impact on other species only if you are not reproducing, plus be a vegan

  21. There is no evolutionary point of view. Evolutionary theory only describes what is, it cannot determine what we "should" do

  22. (I don't want this species to exist for much longer. I don't like it. ) There is nothing intrinsic about "wanting to preserve species" since species is itself an artificial made-up category just like other taxonomic groups. Intrinsic desire is to preserve yourself and your loved ones, not "species"
