Will Space Technology Create Green Solutions for Earth?

So far, the effort to figure out a way for safe, sustainable development for humankind has been tied to planet Earth, but some are beginning to think not just “outside the box”, but outside the entire atmosphere. They believe that the exploitation of space could be a potential solution to the earth's environmental crisis.

Political scientist Rasmus Karlsson suggests that space could provide us with a sustainable future that is simply not possible from an earthbound-only perspective.

Karlsson, a researcher at the University of Lund, Sweden, believes that over the years, two strands of thought on sustainable development have emerged. They are ecologism and environmentalism. Ecologism offers a solution by emphasizing the need for major socioeconomic reform aimed at a post-industrial era. Environmentalism, in contrast, focuses on the preservation, restoration, and improvement of the natural environment within the present framework.

However, Karlsson, suggests that there is a third approach to sustainable development that has until now been excluded from the agenda - namely a large-scale industrial expansion into space.

He suggests that access to the raw materials found on the Moon as well as unfiltered solar energy could be used to increase dramatically our stock of resources and energy while providing unlimited sinks for pollutants. Such an approach would satisfy two of the most demanding issues regarding sustainability, finding renewable energy sources and the disposal of pollutants.

Resource scarcity, pollution, and dwindling fossil fuels, have become of serious environmental concern in the last few decades. As such, environmentalists have called for massive reductions in energy and material consumption. Seemingly unrelated but running in parallel is that the promise of space exploration has been limited to technological optimists whose economic framework rarely acknowledges any such scarcity. Karlsson suggests that it is time to reconcile the politics of scarcity with this technological optimism and to devise a unified political vision for the 21st century that will lead to a truly sustainable planet by extending our reach into space.

Some worry that industrializing space would be a cop-out from finding sustainable solutions on Earth, but others believe the two can go hand in hand. As the world population grows, it seems inevitable that we will run out of space and time for creating the perfect world on just one planet. For certain, the sustainable development problem is a vast and complicated concern for which there are few easy answers. It’s also worth noting that many who criticize industrializing space are not themselves willing to give up all potentially polluting “modern” conveniences while we search for more long-term solutions.

Space Exploration, environmentalism and social justice should be the holy triade of the future. By pushing industry off world we support the continued industrialization and growth based economies that the west has succeeded on.

What you are proposing is inherently evil. Humanity should not expand like a virus into space, consuming everything in its path. We need to retreat back into an ecologically sustainable niche, reducing our population and our level of technology back to sane levels. This can only be done by reigning in individual criminal behavior, and instilling from a young age the proper sustainable behavior.

Humanity will perish if we do not become a multi planet species. Being a parent I cannot let this happen. I agree that our exploitive ways must change but how would one "reign in" criminal behavior? Dictatorship? That will only cause rebellion. IF we reduce our technlogy to the point where we cannot get off Earth than what do we do when an asteroid strike becomes inevitable? Our ecological niche will be destroyed. Changing conscouness requires empathy, pateinets and the will to change. We start that shift by teaching our children to respect the Earth and all it's inhabitants, (Social Justice/Environmentalism) simultainiously we undertake the greatest of adventures being space exploration. We can heal Terra, ourselves and populate the Universe in empathetic and well organized ways but the retreat you mentioned is not viable.

Specifically, there was a recent article about putting a giant solar collector(s) in orbit and beaming the energy to earth.Off the top of my head this seems like it should be feasible way to supply earths energy needs with an economic commitment probably on the order of e.g. a manned mission to Mars.What do readers know about this technology?
