The cultivation of Miscanthus sinensis x giganteus on a polluted soil near Copsa Mica -Romania has started in 2008. Since then every March and August the roots and stems have been analyzed, showing a very low amount of heavy metals in the aerial parts in February, when the harvesting takes place. The combustion properties of the material are similar to those of lignite, but without sulphur and with low ash amount. Because cultivation of edible plants poses the risk of heavy metal entering into the food chain, and soil remediation is unlikely, the cultivation of this plant and its subsequent usage as biofuel could become a feasible solution for the sustainable use of the soils polluted with Cd and Pb.

The knowledge, perception, and behavior of young people toward ecotourism are important for the sustainable development of this sector. The purpose of this research is to evaluate and analyze the knowledge of young Romanian students about ecotourism and the main ecotourism destinations in Romania, their behavior in relation to the practice of this form of sustainable tourism at the local level in the last 2 years (2020 and 2021), and people’s use of the Internet for planning holidays and digital applications while traveling in nature. A quantitative research was conducted based on a self-administered questionnaire, structured in 13 sections on ecotourism, to which were added the sociodemographic data of the respondents. The conclusions of the research are that young people know well the main ecotourism destinations in Romania; they choose them according to the beauty of the landscape, multitude of outdoor activities, and the hospitality of the hosts. In the last 2 years of the pandemic, young people have visited several times the main existing ecotourism destinations locally, with an average vacation duration of 1–3 days. The Internet remains the main source of information, and in the field, they use mobile applications that allow the download of digital maps and recognize different plant species. By integrating various activities in nature, in close connection with the local culture, ecotourism can contribute to the sustainable use of local tourism resources. This study provides a detailed and realistic picture of the knowledge and the type of ecotourism experience that young people want. The implications are theoretical and managerial, highlighting the importance of assessing the preferences of young ecotourists, as a basis for developing ecotourism strategies, sustainable use of local tourism resources, and management of protected areas.

The seed husk is commonly called as psyllium or isabgol has a potential role in the treatment and prevention of gastrointestinal and bowel diseases. The intent of this review was to highlight the industrial uses of psyllium for the food products and therapeutic purposes.

The purpose of this article is to analyse political and regulatory frameworks for connecting education and environment authorities in order to reveal opportunities for introducing new activities based on living organisms into the biology curriculum. The article is also proposing a conceptual framework for capacity building based on the analysis of relevant results at the international level, regarding the experiential learning process. Based on the results of this analysis Romania has the capacity to implement new activities under the public curricula for biology in order to
