"Tipping Point for Planet Earth explains why Earth is headed for a tipping point, a change so fast, dramatic, and unexpected that humanity will reel at the consequences. Midway through this century, there will be more than nine billion people on the planet. Already we are using most of the arable land that exists and overfishing the oceans. Water, too, is becoming scarce in many places. The services that humans depend upon--like a supply of clean water, food production, and protection from disease--are subject to dangerous threats as well. We can still keep humanity moving forward by ensuring that the negative changes that are accumulating do not outweigh the positive ones. Tipping Point for Planet Earth offers sensible solutions to our most pressing problems. The grand challenge of the 21st century is to change the endgame from one that looks like a train wreck, to one that sees the train carrying us all into a bright future"--

A century of industrial development is the briefest of moments in the half billion years of the earth's evolution. And yet our current era has brought greater changes to the earth than any period in human history. The biosphere, the globe's life-giving envelope of air and climate, has been changed irreparably. In A World to Live In, the distinguished ecologist George Woodwell shows that the biosphere is now a global human protectorate and that its integrity of structure and function are tied closely to the human future. The earth is a living system, Woodwell explains, and its stability is threatened by human disruption. Industry dumps its waste globally and makes a profit from it, invading the global commons; corporate interests overpower weak or nonexistent governmental protection to plunder the planet. The fossil fuels industry offers the most dramatic example of environmental destruction, disseminating the heat-trapping gases that are now warming the earth and changing the climate forever. The assumption that we can continue to use fossil fuels and "adapt" to climate disruption, Woodwell argues, is a ticket to catastrophe. But Woodwell points the way toward a solution. We must respect the full range of life on earth -- not species alone, but their natural communities of plant and animal life that have built, and still maintain, the biosphere. We must recognize that the earth's living systems are our heritage and that the preservation of the integrity of a finite biosphere is a necessity and an inviolable human right. -- Provided by publisher.

A solution to the prohibitive cost of producing vehicles for further space explorations is Tom Swift Jr.'s new goal. But the success of the young scientist-inventor's project is threatened by the wily Li Ching, a renegade scientist. Banished from his native land because of rebellious acts, Li Ching is now the leader of a ruthless group intent on pirating scientific secrets. But Li Ching and his nefarious confederates are only partially responsible for Tom's troubles. Olin Whaley, an unscrupulous international criminal, proves to be a second formidable obstacle. Despite the ever-present threats of sabotage and piracy, Tom and his friend Bud Barclay are soon taking Tom's latest invention, the Space Kite -- a two-man craft for training future space pilots -- on its test flight. The experiment turns into a harrowing experience when the boys are nearly marooned in outer space. Undaunted by the failure of the Space Kite, Tom quickly discovers the defect and decides to build a larger craft, the Cosmic Sailer. Certain that he has found the key to economical space explorations, the young inventor still has to conquer the sinister forces working against him. How Tom and the Cosmic Astronauts meet this challenge will keep the reader taut with suspense.
