Adjustment and Renovation Policies of Old Industrial Cities
General Secretary Xi Jinping has repeatedly emphasized that China’s carbon dioxide emissions will peak before 2030, and the country will strive to achieve carbon neutrality before 2060. Activities related to industrial production and energy consumption are the main sources of carbon dioxide production. Vigorous promotion of carbon emission reduction in the industrial and energy fields is key to the successful implementation of new environmentally friendly development concepts, and to accelerate the construction of a modern industrial system, which in turn will help achieve carbon peaking, and then carbon neutrality. The old industrial cities have made historical and significant contributions to the formation and improvement of an independent and complete industrial system and national economic system in China, and have been indispensable in the post opening-up reform era, and during the current wave of modernization.

Impact of Micro- and Nanoplastics on Aquatic Organisms
Anthropogenic activities on the aquatic ecosystem have direct and indirect effects that negatively affect biodiversity both in freshwater and sea. Among the main threats to aquatic ecosystems and biodiversity is climate change. Climate change can impact marine and freshwater ecosystems in several ways: ocean warming; sea level rise; the loss of sea ice; a decrease in pH due to increased ocean surface acidity; an increased risk of diseases in marine biota; the loss of habitats such as Coral Reef; pollution; nutrient enrichment; hydrological modifications; the spread of invasive species; and increasing levels of UV light. The production of plastic and its release into the environment is contributing to the loss of biodiversity and is becoming a serious threat to animal redox homeostasis and, subsequently, for human health.

The Impact of Bitcoin on the Environment
While blockchain and distributed ledger technology offer immense potential for applications in transparency, security, efficiency, censorship resistance, and more, they have been criticized due to the energy-intensive nature of the proof of work consensus algorithm, particularly in the context of Bitcoin mining. Bitcoin’s environmental impact has been portrayed in comparison to countries (Netherlands, Ireland, Argentina) and to industries (steel, aluminum, gold, banking, Christmas lights, aviation, tumble dryers, and even the global monetary system). The former is usually preferred by critics, as it gives a sense of the scale of Bitcoin energy consumption. In contrast, the latter is usually preferred by advocates, who highlight that many industries surpass individual countries in energy consumption and this is not usually seen as a problem. Bitcoin’s environmental impact are not confined to GHG emissions but also encompass issues such as e-waste and noise pollution.

Action for Climate Empowerment
Action for Climate Empowerment (ACE) is a term adopted by the United Nations Framework Convention on Climate Change (UNFCCC). It refers to Article 6 of the Convention's original text (1992), focusing on six priority areas: education, training, public awareness, public participation, public access to information, and international cooperation on these issues. The implementation of all six areas has been identified as the pivotal factor for everyone to understand and participate in solving the complex challenges presented by climate change. The importance of ACE is reflected in other international frameworks such as the Sustainable Development Goals (SDGs, 2015); the Global Action Programme for Education for Sustainable Development (GAP on ESD, 2014); the Aarhus Convention (2011); the Escazú Agreement (2018) and the Bali Guidelines (2010). ACE calls on governments to develop and implement educational and public awareness programmes, train scientific, technical and managerial personnel, foster access to information, and promote public participation in addressing climate change and its effects. It also urges countries to cooperate in this process, by exchanging good practices and lessons learned, and strengthening national institutions. This wide scope of activities is guided by specific objectives that, together, are seen as crucial for effectively implementing climate adaptation and mitigation actions, and for achieving the ultimate objective of the UNFCCC.

Vehicle Pollutant Emissions
The combustion of common petroleum fuels like petrol and diesel in IC engines releases the following major species: nitrogen, water, CO2, O2, NOx, CO, unburned hydrocarbons (VOCs), and PM in the exhaust. Secondary species like SO2, N2O, aldehydes, and ammonia can also be produced. CO2 is a GHG and is thus harmful to the global environment but in the amounts leaving automotive exhaust, it is not harmful to human health directly. Water and nitrogen are benign species. The remaining species (CO, NOx, VOCs, PM, and SO2) are pollutants and have harmful health implications. In addition to these exhaust emissions, non-exhaust emissions (as PM) are also produced by vehicles, most notably from brake, tyre, and road wear, and re-suspension of previously deposited roadside dust.

Atmospheric Environment and COVID-19 Pandemic
Since the COVID-19 outbreak, the scientific community has been trying to clarify various problems, such as the mechanism of virus transmission, environmental impact, and socio-economic impact. The spread of COVID-19 in the atmospheric environment is variable and uncertain, potentially resulting in differences in air pollution. Many scholars are striving to explore the relationship between air quality, meteorological indicators, and COVID-19 to understand the interaction between COVID-19 and the atmospheric environment. COVID-19 and air quality, meteorological factors affecting the spread of COVID-19, air pollution, and human health are the main topics. Environmental variables have a certain impact on the spread of SARS-CoV-2, and the prevalence of COVID-19 has improved the atmospheric environment to some extent.

Eco-Agricultural Industrial Chain
In the chain of the eco-agricultural industry, suitable technology should be selected according to the local characteristics from different stages of the source, the process, and the end. In detail, the scientific and proper use of pesticides and fertilizers should be promoted, as well as the application of the biological humic acid organic fertilizer in cultivation. In terms of breeding, it is important to control the source of ecological feed to achieve nutrient recycling. In the processing of agricultural products, all related wastes should be fully utilized for ecological feeds and biological organic fertilizers. In the field of rural living, suitable technology should be chosen according to the actual situation in order to achieve in situ sewage disposal and recycling utilization. Based on all these technological measures and helpful policymaking procedures, water resource protection and water quality improvement could be realized ultimately with the combination of these technologies in the chain of the eco-agricultural industry.

Factors Affecting Akinete Germination and the Ranges of Tolerances
Eutrophic freshwater ecosystems are vulnerable to toxin-producing cyanobacteria growth or harmful algal blooms. Cyanobacteria belonging to the Nostocales order form akinetes that are similar to the seeds of vascular plants, which are resting cells surrounded by a thick membrane. They overwinter in sediment and germinate when conditions become favorable, eventually developing into vegetative cells and causing blooms.
