Слайды и текст этой презентации
Слайд 3The Romans constructed aqueducts to prevent drought and to create
a clean, healthful water supply for the metropolis of Rome.
Слайд 4In the mid-19th century in London Joseph Bazalgette designed the
first major sewerage system.
Слайд 5The field emerged as a separate environmental discipline during the
middle third of the 20th century.
Слайд 6In many cases, as societies grew, action 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 2.
Слайд 7For thousands of years, people have come up with laws
that restrict public actions that could harm the environment. for
example the construction of sewer culverts in London and Paris in the 19th century and the creation of the US national Park system in the early 20th century
