    1. You misunderstand. He’s not saying we’ve brought stuff in from space, he’s saying that we’ve created more synthetic stuff than there is all life on Earth (we’ve also killed a lot of life and turned it into dead junk).

  1. Just a question if we get alot of the products we use from the earth then how are we making it more heavy besides the overpopulation?

    1. @Commander Shepard That’s a specious comparison. It’s not a ton of feathers or stones, it’s a ton of synthetic junk vs less than a ton of living stuff.

    1. the metal weighs the same whether its in the ground or stacked 50stories high. all we have done is displace the weight.

    1. no. we are a contained system. everything on our planet is in perfect synchronicity to create something requires the sacrifice of something else.

  2. Out weigh? So did they calculate the weight of the planet? Impossible and ridiculous cause everything is made out of what we have on our planet. Incredibly stupid

  3. I disagree for the simple fact that we dont even know completely whats on Earth. Plus humans arent going anywhere so our stuff is only going to grow. I think weve out numbered Nature for a long time with our selfishness and greed.
