Only human innovation can grow beyond boundaries

There is no Planet B, yet. The only thing that can grow beyond our own biosphere is our collective intelligence driving innovation. Only human innovation can grow beyond the limits of our planet.

"Only human innovation can grow our boundaries beyond proven safe limits"

Ultimately, the economy cannot grow beyond the physical limits of Mother Earth. Unless, and until it can access resources beyond it. Until that tomorrow, it is the biosphere that limits economic growth. It is the economy that limits the growth of humanity.

Until we reach the stars,"down to Earth" biosphere limits really matter

Within a biosphere-bounded economy, our global economy can only grow up to the safe ecological limits of our biosphere. When those limits are reached, only innovation can safely grow the global economy (and only within the same limits).

To grow the economy beyond the safe living limits of our biosphere, only physical resources beyond our planet can safely grow it further.

The key question is then; what is the safe, genuinely sustainable physical limits of the Earth's biosphere?

Until that is confidentially and scientifically understood, the economy is contained by the biosphere, and not the other way around. The economy can only change from within, not from without; until

Sadly, because everything is contained within, there will be many more Earth wars before humankind ever gets to fight any "Star Wars".
