Solar Cooking in Berlin
In 1992 the United Nations organised an international Conference on Environment and Sustainable Development (also known as 'The Earth Summit') in Rio de Janeiro, Brazil. The conference was triggered by the concern that humanity has no future when we continue to burn such enormous quantities of non-renewable natural resources, such as coal, oil and gas.
At the close of the conference all local authorities worldwide were called upon to initiate a 'Local Agenda 21' in order to introduce a sustainable development in their respective countries. Within the next year the Berlin District Council of Köpenick adopted a plan for a Local Agenda 21, the first local authority in Germany to do so.
