The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star's life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the 'hourglass.' The unprecedented sharpness of Hubble's images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.

Is it possible that with enough research and experimentation, everything can be recyclable? In this way an artificial and self sustaining environment could perhaps be maintained.
Even if we manage to develop full recycling technology, this would only mitigate, not solve our resources problems. Human civilization and economic growth has always been tied to the consumption of ever increase amounts of resources. The alternative is stagnation.
This kind of technology would certainly be vital to the development of space colonies and the preservation of Earth, but we will still need more outside resources to fuel our growth.
In the long run, colonization will be our best shot at preserving Earth without crippling our economical growth, by moving part of our infrastructure out of the planet and gaining us new resources to explore, which would relieve the pressure on the homeword’s biosphere.
