Practise IB ESS SL 1.1.10 by tracing how named people, publications, disasters, agreements and technologies turn environmental awareness into movement or policy action.
Outline two historical influences on the development of the modern environmental movement.
Al Gore produced film, "Inconvenient Truth";
this raised international awareness about global warming;
Rachel Carson published book, "Silent Spring";
this raised awareness about impact of pesticides/DDT on ecosystems / encouraged establishment of EPA in US;
Industrial revolution led to high levels of atmospheric pollution;
the impact of this on human health/living standards promoted great public concern/interest in pollution;
John Snow made connection between water quality and spread of cholera/water borne disease;
this led to public concern to manage water quality standards/introduce water treatment;
Passenger pigeon in US became extinct through overhunting;
this unexpected extinction led to first conservation efforts in US / Woodrow Wilson setting up first National Parks;
Wackernagel \& Rees introduced concept of ecological footprint;
this model has gained widespread recognition as a means of evaluating environmental impacts of societies/populations;
For each of the TWO examples, award [1 mark] for naming and stating influential action and [1 mark] for describing/developing their influence on environmental movement
