Ever since people first realized that their health and well-being were related to the quality of their environment, they have applied thoughtful principles to improve the quality of their environment. The ancient Indus civilization utilized early sewers in some cities. The Romans constructed aqueducts to prevent drought and to create a clean, healthful water supply for the metropolis of Rome. In the 15th century, Bavaria created laws restricting the development and degradation of alpine country that constituted the region's water supply. In the mid-19th century in London Joseph Bazalgette designed the first major sewerage system. The introduction of drinking water treatment and sewage treatment in industrialized countries reduced waterborne diseases.
The field emerged as a separate environmental discipline during the middle third of the 20th century in response to widespread public concern about water and pollution and increasingly extensive environmental quality degradation. However, its roots extend back to early efforts in public health engineering.
In many cases, as societies grew, actions that were intended to achieve benefits for those societies had longer-term impacts which reduced other environmental qualities. One example is the widespread application of DDT (dichlorodiphenyltrichloroethane) to control agricultural pests in the years following World War II. While the agricultural benefits were outstanding and crop yields increased dramatically, thus reducing world hunger substantially, and malaria was controlled better than it ever had been, numerous species were brought to the verge of extinction due to the impact of the DDT on their reproductive cycles. The story of DDT as vividly told in Rachel Carson's «Silent Spring» is considered to be the birth of the modern environmental movement and the development of the modern field of environmental engineering.
Conservation movements and laws restricting public actions that would harm the environment have been developed by various societies for millennia. Notable examples are the laws decreeing the construction of sewers in London and Paris in the 19th century and the creation of the U.S. national park system in the early 20th century.

ENVIRONMENTAL MANAGEMENT
Environmental resource management is the management of the interaction and impact of human societies on the environment. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors affected by conflicts that rise between meeting needs and protecting resources. It is thus linked to environmental protection and sustainability.
The three main issues that affect managers are those involving politics (networking), programs (projects), and resources (money, facilities, etc.). Environmental management is therefore not the conservation of the environment solely for the environment's sake, but rather the conservation of the environment for humankind's sake.
Environmental management involves the management of all components of the biophysical environment, both living (biotic) and nonliving (abiotic). The environment also involves the relationships of the human environment, such as the social, cultural and economic environment with the biophysical environment.
As with all management functions, effective management tools, standards and systems are required. An environmental management standard or system or protocol attempts to reduce environmental impact as measured by some objective criteria. The ISO 14001 standard (ISO – International Standardization Organization – Международная организация стандартизации , МОС) is the most widely used standard for environmental risk management. Other environmental management systems (EMS) tend to be based on the ISO 14001 standard and many extend it in various ways.
