The purpose of this research is to improve students' critical thinking skills towards environmental problems through mini-project practicum activities on the concept of understanding public perceptions of environmental problems. This research is descriptive research using a qualitative approach. The subjects in this study were Semester II class E students who took Environmental Science courses in the Even Semesters of the 2019/2020 Academic Year. The instrument used to measure critical thinking skills using indicators developed by Ennis are 1) Elementary, 2) Clarification Basic Support, 3) Inference, 4) Advanced Clarification, 5) Strategies and Tactics. Results The average critical thinking ability of 20 students is in the medium category (average score of 69.54). Of the 20 students, 10% were in the very high category, 30% in the high category, 25% in the medium category, and 35% in the low category. Indicators of students' critical thinking in 5 aspects, each of which has an average value that is in the medium category

This article includes a theoretical review of Social Entrepreneurship (SE) due to the gradual increase in the need for new businesses, but also for solutions to social and environmental problems. First, a brief introduction is given explaining why it is important today to have a correct definition of ES. Additionally, the concept of entrepreneur and its different types are defined to create a context and thus be able to talk about the subject. Likewise, a literature review is carried out to achieve a better understanding of an avant-garde concept such as this type of entrepreneurship. Finally, the article concludes with the most important points covered throughout the writing, in addition to a definition of entrepreneur and social entrepreneurship made after analyzing the information found.

The DPSIR model is a conceptual model established by the European Environment Agency to solve environmental problems. It provides an overall framework for analysis of environmental problems from five aspects: driving force (D), pressure (P), state (S), impact (I), and response (R). Through use of the DPSIR model framework, this paper presents the SEEC model approach for evaluating watershed ecological security. The SEEC model considers four aspects: socioeconomic impact (S), ecological health (E), ecosystem services function (E), and control management (C). Through screening, 38 evaluation indicators of the SEEC model were determined. The evaluation results showed that the ecological security index of the study area was >80, indicating a generally safe level. The lowest score was mainly attributable to the low rate of treatment of rural domestic sewage. The water quality status was used to evaluate the applicability of the SEEC model, and the calculation results indicated that the higher the score of the ecological security evaluation results, the better the water quality status. The findings show that the SEEC model demonstrates satisfactory applicability to evaluation of watershed ecological security.

The aim of this chapter is to analyze nationalism and populism as the driving forces of economic deglobalization processes and regionalism. The analysis departs from the assumption that the economic deglobalization processes respond to more complex dynamic forces created by the economic, financial, and the most recent sanitary crisis that blocks the continuity of economic globalization. Moreover, at the center of the analysis is the conceptualization that both globalization and deglobalization are two faces of the same coin, but with opposite driving forces. These driving forces of deglobalization lead to regional and more local solutions to economic growth and social and environmental problems.

Organic pollutants cause many environmental problems to our environment because of their toxicity, non-degradation and ability to long-range transport. The most common organic pollutants are known as persistent organic pollutants (POPs) and are known as hydrocarbons. Effective techniques for the removal of hydrocarbons and heavy metals from soil have drawn great attention. Remediation techniques represent one of the most important of these techniques because of their gentle impact on the environment. The study highlights numerous methods for Physical and chemical remediation techniques with explanation of the ability of some plants and agricultural wastes for remediation.

Environmental problems are enormous around the world and threaten the global environment. In most cases, these problems are caused by rapid growth of population and poverty. Climate change and sustainable development are inter-linked and are priority issues in the development continuum. Any adverse impact on the environment and biodiversity can cause the restriction of resources and limit available options. Concerted efforts of all the states can bring positive result to address the effects of climate change. Compliance with the treaty provision and sharing of resources and actions among the states can ensure proper utilization of resources and sustainable development.

This chapter revolves around the value and relevance of the use of active methodologies in education for sustainability, focusing especially on non-university levels of education. It begins with a conceptualization of active methodologies and exposes what are the most used, recognized, and best valued active methodological tools among teachers. It also reviews the origins of these methodological tools, their evolution, their potentialities and limitations, and the demands that arise in the educational context in view of the need to find a solution from the educational spheres to environmental problems. This chapter analyzes the actual use made of these methodologies in educational centers and finds a justification in the advances that neuroeducation and constructivism have contributed to the educational field in recent decades.
