The unethical overuse of antibiotics to seek to achieve a shortening of the treatment period raises the cost of health services and poses a threat to humanity due to the gradual development of antibiotic resistance. Other consequences of our modern passion for antibiotics have appeared. Small concentrations of antibiotic residues in sewage waters slow down the metabolism of anaerobic microorganism thereby reducing the overall performance of the anaerobic fermentation used to detoxify and digest sewage and other collected organic wastes. Reduced (...) biogas yields represents a serious threat to the energy self-sufficiency of some waste-water treatment plants, so it might change them from energy producers into energy consumers. Morally justifiable production of renewable energy from bio-waste is also threatened by antibiotic residues that remain in the bio-waste. (shrink)

During the last decade, Central Europe became a cynosure for the world for its unparalleled public support for renewable energy. For instance, the production of electricity from purpose-grown biomass received approximately twice the amount in subsidies as that produced from biowaste. Moreover, the guaranteed purchase price of electricity from solar panels was set approximately five times higher than that from conventional sources. This controversial environmental donation policy led to the devastation of large areas of arable land, a worsening of food (...) availability, unprecedented market distortions, and serious threats to national budgets, among other things. Now, the first proposals to donate the purchase price of electric vehicles from national budgets have appeared for public debate. Advocates of these ideas argue that they can solve the issue of electricity overproduction, and that electric vehicles will reduce emissions in cities. However, our analysis reveals that, as a result of previous scandals, environmental issues have become less significant to local citizens. Given that electric cars are not yet affordable for most people, in terms of local purchasing power, this action would further undermine national budgets. Furthermore, while today’s electromobiles produce zero pollution when operated, their sum of emissions remains much higher than that of conventional combustion engines. Therefore, we conclude that the mass usage of electromobiles could result in the unethical improvement of a city environment at the expense of marginal regions. (shrink)

Every corporation has an economic and moral responsibility to its stockholders to perform well financially. However, the number of bankruptcies in Slovakia has been growing for several years without an apparent macroeconomic cause. To prevent a rapid denigration and to prevent the outflow of foreign capital, various efforts are being zealously implemented. Robust analysis using conventional bankruptcy prediction tools revealed that the existing models are adaptable to local conditions, particularly local legislation. Furthermore, it was confirmed that most of these outdated (...) tools have sufficient capability to warn of impending financial problems several years in advance. A novel bankruptcy prediction tool that outperforms the conventional models was developed. However, it is increasingly challenging to predict bankruptcy risk as corporations have become more global and more complex and as they have developed sophisticated schemes to hide their actual situations under the guise of “optimization” for tax authorities. Nevertheless, scepticism remains because economic engineers have established bankruptcy as a strategy to limit the liability resulting from court-imposed penalties. (shrink)

The European Union’s funding of electricity made of biogas that is obtained from purpose-grown plants accelerated the global boom of renewable energy two decades ago. Tens of thousands of biogas plants were built in EU farms soon after. As this specific trend toward renewable energy globally spreads, it has the potential to alter the features of agriculture in the future. Such conceptual changes are related to a variety of socio-economic and environmental implications that manifest itself over a large time scale. (...) Regarding renewables made of purpose-grown plants, a majority of reservations are related to its production economy, particularly since these biofuels are expected to compete with food or feed. So far, little attention has been paid to the fact that the fields of farms that run biogas stations are subject to shortly repeated erosive crops followed by the intensive application of the fermentation residues obtained. The various types of soil on different European farms, which have been operating biogas stations for at least two decades, were analyzed. It was revealed for the first time that such practices cause soil degradation and pose a threat to food production, which has been overlooked until now. The relations between ethical and economical points of view are discussed. (shrink)

Despite the size and thanks to the rich brown coal reserves, the Czech Republic is one of the leading energy producers in Europe, and the 7th biggest exporter of electricity in the world. However, following the climate change mitigation, the novel energy policy that enhances the reduction of coal mining is about to be implemented. A preliminary material flow analysis of the Czech energy sector was carried out. The data obtained confirmed that this government act would result in a dramatic (...) reduction of revenues from electricity sales. Conversely, increased costs would be necessary in order to modernize nuclear power plants and promote the production of renewable energy. In addition, the economic analysis revealed that the act might be prejudicial to economic relations in Central and Western-European countries as some of them are significantly dependent on the electricity imported from the Czech Republic. Disputes between engineers and politicians were highlighted. The aforementioned interrelations were subsequently analyzed and a conclusion was made stating that global interests should have the highest moral priority. (shrink)
