Wow. This type of density of life was probably most of earth before humans changed things.

• oceanplexian 5y ago
  The Earth had the greatest density and biodiversity of life hundreds of millions of years ago during the time of the Dinosaurs, on a much warmer planet when atmospheric CO2 was >5 times what it is today. Unfortunately, non-anthropogenic climate change, not humans, was what wiped out most of that life.

    And then came the humans and wiped the rest of it. It is much better now. You can walk safely at night without being scared of animals.

      In some parts of the world... Where I live it's not unusual to see a grizzly or a herd of elk outside your door.

    Those previous changes occured at a different time, you cannot use that as an arguement to someone talking about human impact. It's like saying Covid-19 didn't killed because there has been more death during the black plague.

    I think the non sequitur argument you're making is that somehow humans are not to blame because natural cycles have caused greater extinction? The latter implies nothing about the former, it's an invalid argument.

    Why just dinosaurs? There were a lot of other fascinating *saurs besides dinosaurs.
