Space tourism is recreational space travel, whether by government vehicles, such as the Russian Soyuz and the International Space Station (ISS), or by vehicles built by private companies. Since the flight of the world’s first space tourist, American businessman Dennis Tito (28 April 2001), space tourism (orbital) has been slowly growing. Orbital space tourism is very expensive, so a number of private companies have decided to concentrate on building much cheaper suborbital vehicles, designed to take passengers to altitudes of up to 100 km. On 4 October 2004, SpaceShipOne, funded by Virgin Galactic and designed by an American engineer, won the X Prize and, in doing so, ushered in a new era of commercial crewed spaceflight and space tourism. Since then, the design and construction of suborbital spacecraft have become increasingly popular. Such ships, in principle, do not have the ability to cross the imaginary 100 km boundary and enter the Cosmos area. However, space tourists can find themselves weightless for a few minutes. In fact, not only technical but legal difficulties have caused suborbital tourism to develop at a slow pace so far. This article concentrates on some legal challenges regarding space tourism, not going into details about states’ politics and international organizations’ activities.

Adopting a long-term perspective has helped companies survive in difficult times and overcome economic crises, recessions, and pandemics such as the current COVID-19. At present, the project management approach is changing from more authoritarian management models to frameworks that are based on the management of people and society. This article researches the concept of sustainable leadership in the project management profession. It evaluates the level of sustainable leadership among project managers in Spain using the Avery and Bergsteiner’s (2011) model of bees and locusts as a reference framework (Bee and Locust Sustainable Leadership Model). A qualitative study was carried out based on the analysis of the responses given by sixty-eight project managers in Spain who answered a 52-point ques-tionnaire. The findings yielded interesting results. It was found that in projects considered as temporal organizations, companies tended to employ a mixture of bee and locust’s leadership elements. Respondents recognized the importance of employee training and development, and most considered that it was essential to consider the environment when determining the organization’s commercial objectives. However, based on this study’s findings, the project management profession still has a long way to go as regards the practical implementation of sustainable leadership.

The Carbon Footprint (CF) of agriculture must be substantially reduced to help avoid catastrophic climate change. This paper examines the ratio of Greenhouse Gas (GHG) emissions to protein as an indicator of the CF of the major Canadian livestock commodities using previously published results. The GHG emissions for these commodities were estimated with a spreadsheet model that accounted for all three GHGs, the complete life cycles of each livestock type and the livestock interactions with the agricultural land base. The indicator results reviewed here included the responses to livestock types and diets, livestock versus plant protein sources, spatial scales and geographic differences. The sensitivity of the results shown suggest that GHG-protein ratios could provide valuable guidance for producers and consumers to reduce their GHG emissions. For example, diverting feed grains from beef feedlots to hog production would substantially reduce the CF of red meat, although still not as low as the CF of poultry products. The complete proteins derived from pulses have much lower CF values than all livestock products.
