  The mass of the Earth is 5.972 × 10^24^, so you would need 5.972 × 10^20^ humans of 100 Kg each all turning in the same direction to make the Earth rotate 1% the other way (so about 597,200,000 trillion humans).

  Whatever amount of people it’d take, the effect we’d make, would cancel at break.

    I was going to say a similar thing, how are you going to get gone without canceling it out.

    But also if you walked away from the equator then walked until you were directly north/ south of your home before walking home, some effect would remain.

      I don’t believe that to be correct, but I’m to stupid to refute you. So I’ll take it as facts. Thank you for enlightening me.

        It’s because your return journey is closer to the axis of the earth so your action has less torque.
