ABSTRACT
Global warming has become a reality: between 1906 and 2005, global mean temperatures have risen by 0.7°C, indicating that a further 2°C increase in the temperature of Earth’s atmosphere by the middle of the twenty-fi rst century (relative to nineteenth-century fi gures) is inevitable, no matter what measures might be taken (Schulz, 2008, p14). Any and all political parties and organizations have been discussing a wide variety of approaches aimed at reducing anthropogenic, climate-relevant gases. Even if the impact of global warming has not yet been acutely felt everywhere, in the long run, climate change poses a major challenge for feeding an ever-growing world population.
