Book Description
يعتبر الهواء المحيط بنا مزيجاً فريداً من الغازات، تحيا النباتات والحيوانات بأخذها ما تحتاج منه من الأوكسجين. ولكن خلال القرنين الأخيرين، تبدل هذا المزيج الفريد بسبب الأنشطة البشرية، حيث قامت المصانع والعوادم بضخّ الأدخنة والأبخرة إلى الهواء مما أدى إلى تلويثه. وهذا الكتاب يلقي الضوء على الهواء وأهميته لكل كائن حي على كوكب الأرض، كما أنه يتفحص مصادر الطاقة المختلفة التي يستعملها البشر، وتأثير التلوث الذي يسببه الإنسان على نوعية الهواء الذي نحتاج إليه. وقد تضمن المؤلف العديد من الصور الفوتوغرافية والرسوم البيانية بالإضافة إلى الخرائط التي تبين مصادر الطاقة بمناطق استهلاكها. يضاف إلى ذلك العديد من التجارب العلمية المبسطة ذات الأهداف التعليمية.
