      +Kazi Islam, we seem to be one right now. The rate of extinction is currently way higher than it naturally appears to be. Scientists have begun naming our current geological age "anthropocene" (human age) because of this and other aspects of our impact on earth's ecosystem.
      If we don't change things rapidly, we will be responsible for incredible extinction events.

      @raymondv.m4230 7 ปีที่แล้ว +5

      sertaki We're not the only ones doing it though. It's been a known sign of mass extinction when large creatures of an ecosystem begin to die off and it's not just human causes, natural deaths across many large animals are happening quicker than they can reproduce (not that humans really are helping with that). These are the beginning sign of mass extinction if I recall correctly from my geology 101 class.

      A story to share. I was at the beach with my family in the morning, and we looked out at sea and saw hundreds of dead horseshoe crabs, later that day I picked one up by its tail, then buried it and marked its grave with a stick.

  • @jisookim6904
    @jisookim6904 7 ปีที่แล้ว +581

    For further information:
    - about a third of the blood is removed during harvesting
    - the most devastating to the population was by far the fishing industry until finally regulations were introduced some time around 2000, until then millions (!!!) of Horseshoe crabs were taken each year as bait for US fisheries (exact numbers aren't available because no one monitored it)
    - Horseshoe crabs aren't real crabs
    - there's a couple of species, some of them live in Southeast Asia, the biggest population lives in Delaware though
