Food. Clothing. Shelter. Gardens. Pets and wildlife. Medicines. Zoos and parks. When you think about it, natural sciences play huge roles in our everyday lives- even in a urban setting like Philadelphia!
Food science is the applied science devoted to the study of the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public. Food processing is the transformation of raw ingredients, by physical or chemical means into food, or of food into other forms.
Biotechnology is the use of living systems and materials to develop or make products. For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine. In the late 20th and early 21st centuries, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene techniques, applied immunology, and development of pharmaceutical therapies and diagnostic tests.
