Фрагменты работ
1. Прочитайте текст и ответьте на вопросы.
1. When did people realise that their health was related to the quality of their environment? 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.
2. When did the field of environmental engineering separate from environmental science? 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.
3. What benefit was achieved by constructing drinking water treatment and sewage treatment systems? 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.
