Harvesting space for a greener Earth
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.

Opportunities for minority contracting in Pittsburgh
African-American economic conditions in the Pittsburgh region continue to be among the worst in urban America, while African-Americans continue to do well in urban areas such as Atlanta. For example, the Atlanta region ranks sixth best whereas the Pittsburgh region ranks last among the 50 largest metro areas on Black median household income. African-American households in the Atlanta region have 74 percent more annual income than African-American households in the Pittsburgh region. Many people may not realize it, but one reason for Atlanta's success is that local government led the way in the 1970s by starting to use and develop many minority firms for construction and professional services. When local government seeks out, supports, and uses many qualified minority firms, the firms gain experience, expand, and employ people who live in and contribute to the region's economy. When a region such as Pittsburgh does not utilize many minority firms, these firms don't compete for or receive public contracts, they struggle and go out of business, jobs are lost, unemployment and poverty are higher, neighborhoods have worse living conditions, social service needs are greater, the tax base is lower, and disparities in educational attainment continue.
