This paper examines the role of existing and future international laws and international organizations in mitigating climate change and pandemic disease issues. Both of these issues are urgent and significant sustainable development goals. A carbon market is a practical approach reformed by the Paris Agreement that helps climate mitigation, especially in developing countries. Available evidence concludes that adversity in biodiversity and climate change forms a vicious circle that lacks international cooperation, and the paper proposes solutions. Vaccination is at the center of discussion as the Covid-19 pandemic raises global awareness of public health issues. Organizations are expected to be more effective and better provide access to the vaccine for developing countries. Therefore, better international treaties must be established, which are expected to include forming independent affiliates and enhanced financial assistance, technical assistance, and so on.

With the rapid development of science and technology, the Internet has gradually become a channel for teenagers to interact with the outside world. Therefore, from the perspective of developmental psychology, this study combines Kohlberg’s moral theory and Erikson’s development theory to analyze the influence of the Internet on adolescents. In addition, this study provides strategies for teachers and parents to strengthen the positive effects of the Internet and reduce the negative effects of the Internet. The result shows that it can bring some benefits to adolescents, such as helping adolescents to achieve self-identity and meeting the needs of communication and emotional expression. However, it can also have a negative influence on some teenagers. For example, harmful Internet information may make them set up the wrong values. In addition, cyberbullying, a new form of bullying derived from the Internet, can lead to depression problems in adolescents. Specifically, for positive effects, teachers can ask classmates to complete homework that requires using the Internet, and parents can teach children to use the Internet to a limited extent. For negative influences, teachers and parents should convey correct values to teenagers, communicate with teenagers on an equal footing, and help teenagers establish a growth mindset.

This study examines the critical definitions and debates of geographic inequality by looking at the development of inequality to clarify the pressing geographic inequality challenges facing the UK, taking Darlington as the target area for developing locally applicable research methods. Since the negative impact of the historical process of unequal development in Britain, innovative investigations are called to solve this problem. This paper discusses the deep-rooted inequality in Britain by reviewing the information on geographical inequality and analysing the data from multiple spatial perspectives. The data analysis shows that the UK is one of the unequal countries in the industrialised countries and suffers from increasing domestic inequality challenges. In addition, the economic performance of London is far better than that of other regions. London has an extreme inequality between the bottom and top income levels. In addition, the data research illustrates that Darlington has optimistic trends and low levels of educational qualifications, and average weekly income. Secondly, due to the lack of research on inequality and trends in small regions, the paper utilised the attitudinal survey design as a research method to attempt to explore the correlation between population education and income and to understand further the inequality situation in the area by the relevant authorities.

This paper focuses on the relationship between microglia and depression. Depression is affected by multiple structures, cells, and hormones, including the hippocampus, amygdala, hypothalamic-pituitary-adrenal axis, gut microbiota, stem cells, and glucocorticoids. This paper explores the relationship between microglia and structures, how these structural changes lead to increased concentrations of microglia leading to depression, and current treatment options for depression. Treatment options include drug therapy, electroacupuncture, and stem cell therapy. All of these treatments significantly impact the cure of depression and, at the same time, affect the overactivated microglia cells. It is concluded that the production of depression is closely related to microglial cells.

The idea of educational equity has a long history, and the pursuit of educational justice is a long-standing human society ideal. China is one of the largest educational countries in the world. The government has been working hard for educational equity. With the continuous development of society, many educational hidden dangers left in the past have gradually emerged. The main research object of this paper is the inequity phenomenon in modern China’s education circumstances, and through the research data, policies, and existing research theories to look for the root of the inequity in China’s education. The results of the study found that it is difficult to generalize the root causes of the existing educational inequity in China. Policies, resources, and regions are one of the main manifestations of inequity, among which resources are the most important. Their origins are interrelated, and inequality of opportunity is one of the reasons. This paper puts forward some feasible schemes to improve the current situation of educational inequity in China from the perspective of different areas.

This paper is based on the Seventh National Population Census Bulletin and the author's two years of experience working in a charitable organization in Shanghai, China. This paper aims to describe three trends- urbanization, digitalization of urban areas, and aging population-in China, and the problems the society, especially the elderly, is facing when these three inevitable tendencies intersect. The PEST model is used to analyze and describe the problem above. In the PEST model in this paper, different solutions were listed. In the PEST model, the author puts forward corresponding policy suggestions from the perspectives of politics (public administration), economy (fiscal and consumption problems of the elderly in the digital city), society (the life of the elderly under the epidemic policy), and technology (the use of digital products by the elderly). In terms of administration, a certain number of staff should be kept helping the elderly in governmental offices, or special passes should be opened for the elderly. Economically, protect the labor rights of the elderly and participate in their capable work. Keep offline consumption scenarios going and carry out aging adaptation. From a social perspective, it will facilitate the lives of the elderly in the epidemic era and reduce the nucleic acid code information procedure. Increase the mobile phone use education for the elderly from the perspective of science and technology.

In recent years, along with the diversified development of culture, two-dimensional elements in posters, posters, logos, and many other types of graphic design have become contemporary testimonies and symbols. However, many graphic designers have neglected to improve their structure and creative abilities and started to rely on the software and tools they use to produce art, leading to reduced quality of output and making everything look the same in our information-saturated world, which in turn impact the audience who has developed aesthetic anxiety and facing challenges to absorb the information they truly need in an ocean of images that is chaotic and fast-moving. In light of this, this paper analyzes the creative process and the application of contemporary graphic design. It discusses the problems in using two-dimensional elements and the corresponding solutions, such as starting from images, words, and colors simultaneously. These suggestions can significantly help to improve the effect of graphic design and creative industries to relieve the aesthetic anxiety of the public and provide them with better solutions and the ability to absorb the information they need.
