Of some 10000 bird species in the world, 514 are to be found in Europe. Of these, twenty-six European species are globally threatened & risk extinction if their populations are not actively built up. This series of action plans for Europe's most threatened species is the result of a joint project carried out by BirdLife International, in collaboration with Wetlands International, involving over 370 experts in almost every European country. This book will be of interest to conservationists at both national & local level, educators & all those interested in the conservation of Europe's bird heritage.

Book Description
Do you know silica, the tetrahedra of silicon and oxygen constituting the crystals of New Agers and the desiccant in a box of new shoes? It's no mere mundane mineral. As chemically reacting silicate rocks, silica set off the chain of events known as the origin of life. As biomineralized opal, it is the cell wall, skeleton, spicules, and scales of organisms ornamenting numerous lobes of the tree of life. Cryptocrystalline silica made into stone tools helped drive the evolution of our hands and our capability for complex grammar, music, and mathematics. As quartz crystals, silica is impressively electric and ubiquitous in modern technology (think sonar, radios, telephones, ultrasound, and cheap but precise watches). Silica is inescapable when we take a drink or mow the lawn and it has already started to save the Earth from the carbon dioxide we're spewing into the atmosphere. This book tells these scientific tales and more, to give dear, modest silica its due.
