  In Green Lewisham we are invited to explore the surprisingly numerous green spaces in the Borough of Lewisham in south east London. Rivers, trees, grassy glades and wildlife are round almost every corner, hidden between houses and alongside railway lines and all lying less than ten miles from Trafalgar Square in central London. We have a brief history behind the many calming and natural sites and the photographs tempt us to go walking every day, and at all times of the year, as the trees change from bare branches to green leaves and then the brilliant jewel-like colours of the autumn. Discover herons and egrets, swans, and many, many species of birds as well as the ever-present ring-necked parakeets. Walk along the centuries-old River Ravensbourne and its tributaries, or find stunning views of London from the hilltops. Lewisham is celebrated as the London Borough of Culture in 2022. Candy Blackham has given us a unique book which opens our eyes to appreciating and enjoying the natural, green spaces in this special year.

  The astonishing story of America’s airwaves, the two friends—one a media mogul, the other a famous inventor—who made them available to us, and the government which figured out how to put a price on air. 
  This is the origin story of the airwaves—the foundational technology of the communications age—as told through the forty-year friendship of an entrepreneurial industrialist and a brilliant inventor. 
  David Sarnoff, the head of RCA and equal parts Steve Jobs, Jack Welch, and William Randolph Hearst, was the greatest supporter of his friend Edwin Armstrong, developer of the first amplifier, the modern radio transmitter, and FM radio. Sarnoff was convinced that Armstrong’s inventions had the power to change the way societies communicated with each other forever. He would become a visionary captain of the media industry, even predicting the advent of the Internet. 
  In the mid-1930s, however, when Armstrong suspected Sarnoff of orchestrating a cadre of government officials to seize control of the FM airwaves, he committed suicide. Sarnoff had a very different view of who his friend’s enemies were. 
  Many corrupt politicians and corporations saw in Armstrong’s inventions the opportunity to commodify our most ubiquitous natural resource—the air. This early alliance between high tech and business set the precedent for countless legal and industrial battles over broadband and licensing bandwidth, many of which continue to influence policy and debate today.

  Today there is no place on Earth that does not harbor invasive exotic species. Invasive plants and animals can be found on every continent, including Antarctica, and within all waterbodies, including all oceans. In our increasingly connected world, with speedy commercial and recreational travel and the global movement of biological matter for food, invasive species are showing up at such a fast rate that there is no way to accurately count how many currently exist or how many are likely to emerge in the coming decades. Monitoring these species and controlling their spread is essential, as we increasingly understand the negative impacts they pose: their threat to our health; the toll they take on our commercial production; and the threat they pose to native ecosystems. 
   
   
   
  This Very Short Introduction provides a clear definition of an invasive species, and considers the myriad ways they are moved around the globe, and the ecological, social, and economic impacts they often impose. Exploring the way Earth's biodiversity is being affected by global change, Julie Lockwood also discusses policy and management approaches to combating the ill-effects of invasive species, and how invasive species fit within the broader context of environmental change.

  A never-before-heard firsthand account of a government insider's experience on the cutting edge of UFO exploration; includes a new afterword"Forget everything you think you know about UFOs - this insider's account exposes the reality... Packed with top grade information, insightful analysis and fascinating anecdotes, Alexander's interesting and controversial book sets the gold standard for titles on this subject." –Nick Pope, author of Open Skies, Closed Minds"Changes the playing field for both true believers and skeptics alike. Alexander strongly warns, be careful what you wish for when asking for presidential intervention.  Success could set the field of ufology back decades." --George Noory, host of Coast to Coast AMWhile still on active duty in the U.S. Army during the 1980s, Colonel John B. Alexander, Ph.D. created an interagency group to explore the controversial topic of UFOs. All members held Top Secret clearance. What they discovered was not at all what was expected. UFOs covers the numerous cases they saw, and answers questions like:• What was really in Hanger 18? • Did a UFO land at Holloman Air Force Base? • What happened at Roswell? • What is Majestic 12? • What is the Aviary? • What does the government know about UFOs? • What has happened with disclosure in other countries? • Has the U.S. reverse engineered a UFO? • Why don't presidents get access to UFO info? UFOs is at once a complete account of Alexander's findings, and a call to action. There are no conspiracy theories here—only hard facts—but they are merely the beginning. Foreword by Jacques F. ValleeIntroduction by Burt RutanCommentary by Tom Clancy
