Tourism is the main cause of a possible environmental disaster

20.05.2018

Scientists have come to an unexpected conclusion regarding tourism, which was previously considered a priority industry for development. As it turned out, it is he who is one of the causes of the upcoming environmental catastrophe.

This conclusion was made by experts working at the University of Sydney. According to the results of their research, it is the tourism industry that should bear its part of the responsibility for increased emissions of greenhouse gases into the atmosphere. Scientists have calculated that after air, water and land tourism became more active, the amount of greenhouse gases from this industry reached 8% of their total emissions.

This is due not only to transportation, but also to a significant increase in the number of catering and entertainment establishments. According to the previously prevailing opinion, tourism causes environmental damage three times less. At the same time, the amount of harmful emissions from the tourism industry continues to grow at a rate of approximately 3% per year.

The largest amount of harmful emissions from tourism is recorded in countries such as the USA, Germany and China. At the same time, in the latter they are growing at a faster pace. In the list of countries where this figure is also becoming threatening, include Brazil, India, Canada, Mexico, Russia, Japan and the UK.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
