In the context of this book, this chapter introduces five factors representing the supply of energy and raw materials, as well as environmental effects on regional and global scales. It remains an open question, which of these factors will become the most determining and when.TRUST 发表于 2025-3-25 10:07:13

Soziales und (ihre) Architektur on a global scale are a major challenge for human societies. The second part of this chapter deals with the definition of systems, their balances, and their properties with special emphasis on dynamic and feedback situations. The third part describes how systems respond energetically to processes i摇摆 发表于 2025-3-25 18:59:44

The first part describes the position of the Earth in the solar system and the present conditions on Earth as a whole as well as in its constituents (crust, ocean, and atmosphere). The second part deals with the driving forces for historic and current changes in the bio组成 发表于 2025-3-25 22:17:48
Sozialraumorientierte Schulsozialarbeite energy coming from the Sun and radiative energy emitted back to space. The atmosphere has a strong additional impact on the global energy balance as it efficiently absorbs infrared radiation coming from the surface of the Earth. As a result of this greenhouse effect, the surface temperature is muc豪华 发表于 2025-3-26 00:43:03

As selected examples, carbon, water, nitrogen, and oxygen cycles will be treated, and in addition aspects of some other material cycles (sulfur, phosphorus, chlorine) as well as interactions of these cycles.

As the most important criterion, human activities in energy conversion should make optimum use of natural cycles, instead of depending on non-renewable fossil raw materials. However, this is possible only if technologies are developed that can cope with the low里程碑 发表于 2025-3-26 18:16:59
