Article Abstract:

Proper nutrition and hydration while on an expedition are crucial. Diets must be varied and appropriate to the environment of the expedition. In hot climates, too much protein is a bad idea and in cold climates, hot food is essential. In humid climates, food storage can be a problem, while in the mountains, the main consideration is weight. The different means of water purification are discussed.

Article Abstract:

British Airways began the supersonic era with the Concorde airplane 20 years ago. The problems of noise pollution, excessive fuel consumption and high price bedevilled the venture until it found the niche of business travel between London and New York. Advantages of the airplane include longer life due to fewer hours of flying.
