Now here is a breakdown by country for resource consumption.
At some point we pay the piper. One way or another. For every person we add - we add to our resource debt. We make the repercussions that much more severe and or more difficult to avoid altogether. This planet, and our country, needs fewer people. Not more. Unless you favor strip mining, fracking, CO2 emissions, etc. Each person means more demand for resources, and ultimately fewer resources available for the rest of us.
For example, anyone who favors eating meat - will want our population to stop growing immediately.
We are currently living beyond our means. At some point our standard of living will be reduced to meet reality. Our population will determine how steep that reduction is.
