Environmental Hygiene
The environment compasses not only the natural surroundings - the air, the water, the plants and animals used for food - but also shelter, modes of transportation and all other products of technology, including pollutants and waste materials; all of which interact to affect health. Environmental considerations become increasingly important during these times of changing emphasis in the fields of energy, economics and technology.Environmental hygiene can be looked at from two aspects, viz. Hygiene at household level and Hygiene at the community level.
