"I think"
it is much more interesting, and instructive, to note that early humans had so much impact on the planet, as Bill (Ruddiman)'s work and much other research is showing," says Alley, author of Earth: The Operator's Manual. "In some ways, our impact per person has probably been dropping"
as we learned better ways to do things, although our population appears to have been growing faster than our
"impact per person dropped",
so we're having more total impact across the planet."

Ruddiman is similarly hopeful that people can learn to have even less impact on the planet, and that investigations into prehistoric people can help explain more mysteries about past climate questions. "I think"
climate science and archaeology both have a lot more to say to each other," he says.

They really don't know do they? More scientific sceince fiction.
