Human civilization has evolved to the point at which we can consider tapping space resources and expanding beyond Earth’s atmosphere. The Introduction surveys possible motivations for large-scale human emigration to space. Since our early ancestors began to move out of Africa, humans have constantly expanded their range. Today, the pattern of human settlement extends from pole to pole. Humans regularly visit the upper troposphere and ocean floor and technology has enabled a few to even reside above the atmosphere in space stations.

For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars are questions that need to be answered if mankind is to migrate into space.

Solar sailing is a topic of growing popular and media interest. Solar sail propulsion will make space exploration more affordable and offer access to destinations within (and beyond) the solar system that are currently beyond our reach. This book describes solar sails, how they work and what they will be used for in the exploration of space in an easily readable manner which does not necessitate any prior knowledge of physics or solar sailing. It discusses current plans for solar sails and also describes how advanced technology, such as nanotechnology, might enhance solar-sail performance. Much has been accomplished recently to make solar sail technology very close to becoming an engineering reality and it will soon be used by the world’s space agencies in the exploration of the solar system and beyond.

The book has four parts, each with multiple chapters which, in turn, contain some references and suggested further reading. Parts 1 - 3 are non-mathematical, while Part 4 contains more detailed technical information.

What was our planet like before the advent of our modern civilization? What effects has our civilization had on the planet and its ecological systems? Paradise Regained discusses these questions and then creates a scenario for the re-greening of Earth. The authors introduce new and innovative ideas on how humankind might use the resources of the solar system for terrestrial benefit. Earth would then become a place for a technologically advanced human civilization to live in synchronization, if not in harmony, with the environment which gave us birth.

Since the formation of our solar system, the resources and ecological state of Earth have undergone many changes. The environmental challenges facing humanity today, as the authors posit them, will not be resolved simply by conservation and Earth-based alternative technologies. Paradise Regained considers the environmental dilemma and highlights the risk of humankind''s future extinction from environmental degradation. Human population growth, climate change, and the strained sustainability of the few remaining habitats for wild life are all discussed.

The authors, however, are not discouraged and offer a potential solution through the development of space. Not only will extraterrestrial resources help avert environmental disaster, but will also provide the basis for continued technological and societal progress. The resources of the solar system will help meet our projected industrial needs and feed our industry once terrestrial sources are depleted. Space-based power generation systems will work synergistically with Earth-based conservation. Paradise Regained concludes with the discussion on how closed ecological systems in space will help us to build a prosperous and sustainable future for all humanity.

What was our planet like in years past? How has our civilization affected Earth and its ecology? Harvesting Space for a Greener Planet, the Second Edition of Paradise Regained: The Regreening of the Earth, begins by discussing these questions, and then generates a scenario for the restoration of Earth. It introduces new and innovative ideas on how we could use the Solar System and its resources for terrestrial benefit.

The environmental challenges that face us today cannot be resolved by conservation and current technologies alone. Harvesting Space highlights the risk of humankind’s future extinction from environmental degradation. Population growth, global climate change, and maintaining sustainability of habitats for wildlife are all considered, among other issues.

Rather than losing heart, we need to realize that the solutions to these problems lie in being good stewards of the planet and in the development of space. Not only will the solutions offered here avert a crisis, they will also provide the basis for continued technological and societal progress. Tapping the resources of near-Earth asteroids will lead to methods of diverting those asteroids that threaten Earth. Space-based terrestrial power generation systems will work synergistically with Earth-based conservation.

This book needs to be read urgently and widely, if we are to save ourselves from environmental disaster, reduce the risk of catastrophic cosmic impacts, and build a prosperous and sustainable future for all the creatures of Earth.
