Recently, the concern for global environmental issues has risen all over the world. The increment in concentration of the heat-trapping greenhouse gases that causes global warming in earth’s atmosphere became a serious problem. The level of the sea rises by melting glaciers when global warming advances it. Forecasting the changes of carbon dioxide concentration is a major issue to maintain the stability of the Earth and its species. The measurement of carbon dioxide is also important for agriculture and local industrialization. The density of carbon dioxide varies depending on the environment. The development of a low cost device that detects carbon dioxide density is discusses in this paper. We developed some measurement systems of carbon dioxide for various purpose.

Global Environmental Issues

Education needs an ethical orientation that can help it grapple better with global environmental issues such as climate change and decreasing biodiversity, something called earth ethics. The term ethics is used in an unusual manner, to mean a normativity more basic than concrete norms, principles, or rules for living. The idea of earth is also used in an unusual way, as a kind of concealing, a refusal to disclose itself, while at the same time, constituting a kind of interference with the familiarity of the world. The idea of earth plays on the contrast between living on earth and living in the world. The latter involves the familiar concerns and actions of culture and work, of politics and economics. Earth ethics becomes a call to responsibility coming from the earth—a call to let the earth and earthlings be, to acknowledge their refusal to answer our questions or fit easily into our worldly projects, and to recognize their continuing mystery as beings with their own intrinsic worth. The idea of earth ethics is developed through attending to a set of human experiences. First is an experience of gratefulness toward the earth. This gratefulness not only reveals our finitude, but also our indebtedness to the grace-filled support the earth continually gives us for our worldly projects and concerns. This reveals earth as our home, a dwelling we share with other earthlings. This reveals earth’s fundamental fragility. What seems solid and dependable from a worldly perspective shows up as vulnerability from an earthly viewpoint. The experiences of gratefulness to and fragility of the earth gives rise to feeling a call to responsibility, the core of earth ethics. Earth ethics is a call of responsibility to the earth, one that grows out of our debt of gratitude and the earth’s fragility. It is this normative call that might guide education in its grappling with environmental issues.

The Impact

Background: This research aims to follow the concentration of carbon dioxide (CO2) in the atmosphere and the effect of zero-emission on the ecosystem. CO2 is the most important of the green house gases. Nowadays, the earth is suffering from global warming due to greenhouse gases. The call all over the world is to reduce the emission of the greenhouse gases, mainly CO2. Methods: The research methodology depends on the data of international research laboratories, which follow the concentration of CO2, such as National Oceanic and Atmospheric Administration (NOAA), the USA, and Mauna Loa Observatory in Hawaii. The concern towards CO2 concentration in the atmosphere started in the last century. Results: The industrial revolution did not consider the impact of pollution on the environment. The impact on the environment was noticed only after a clear disturbance in the ecosystem. The emission of greenhouse gases, especially, CO2 is monitored; daily, monthly and yearly. There are different sources of CO2 emissions, such as transportation, factories, burning of forests etc. In fact, CO2 is a harmful as well as a useful gas. It is harmful because of global warming, and useful because of its important role in the photosynthesis process. This process is very crucial for all living things. The research to reduce the emission of CO2. has provided some solutions. Layered materials, MPS3, where M stands for the transition metal, have been used to store hydrogen gas. The hydrogen molecule size is 2.89 Å, and the molecular size of CO2 is 3.3 Å, this means that the CO2 can be captured by the layered materials. The capturing of CO2 is achieved by simulation. Conclusion: We need to reduce the emission of CO2 but not to reach zero emission, because then, there will be no photosynthesis process, which means there will be no life on the earth. Carbon capture and storage is a technology that can capture up to 90% of the CO2, but the biggest obstacle to this approach lies in the inherent thermodynamic stability and kinetic inertness of CO2.

Abstract. The planetary boundaries framework provides guidelines for defining thresholds in environmental variables. Their transgression is likely to result in a shift in Earth system functioning away from the relatively stable Holocene state. As the climate system is approaching critical thresholds of atmospheric carbon, several climate engineering methods are discussed, aiming at a reduction of atmospheric carbon concentrations to control the Earth's energy balance. Terrestrial carbon dioxide removal (tCDR) via afforestation or bioenergy production with carbon capture and storage are part of most climate change mitigation scenarios that limit global warming to less than 2 °C. We analyse the co-evolutionary interaction of societal interventions via tCDR and the natural dynamics of the Earth's carbon cycle. Applying a conceptual modelling framework, we analyse how the degree of anticipation of the climate problem and the intensity of tCDR efforts with the aim of staying within a "safe" level of global warming might influence the state of the Earth system with respect to other carbon-related planetary boundaries. Within the scope of our approach, we show that societal management of atmospheric carbon via tCDR can lead to a collateral transgression of the planetary boundary of land system change. Our analysis indicates that the opportunities to remain in a desirable region within carbon-related planetary boundaries only exist for a small range of anticipation levels and depend critically on the underlying emission pathway. While tCDR has the potential to ensure the Earth system's persistence within a carbon-safe operating space under low-emission pathways, it is unlikely to succeed in a business-as-usual scenario.

Air pollution is an environmental problem that is familiar to residents of absolutely all corners of the earth. It is especially acutely felt by residents of cities where enterprises of ferrous and non-ferrous metallurgy, energy, chemical, petrochemical, construction, pulp and paper industries operate. In some cities, the atmosphere is also severely poisoned by vehicles and boiler houses. These are all examples of anthropogenic air pollution. The subject of the study is the emissions of carbon dioxide into the environment. The purpose of the study is to solve the problem of environmental pollution by harmful substances and preserve the ecology in the world. Methodology. The main indicators characterizing the impact on the environment - CO2 emissions in the global energy sector - have been systematized; two indicators have been identified that determine the level of atmospheric pollution. Results - the scale of the influence of atmospheric air pollution on human health and the entire ecosystem as a whole was revealed.

<p>In the new 'Age of the Anthropocene', the Earth's atmosphere, like other elements of Nature, is rapidly being colonized by a minority of the world's population, at no cost, threatening the security of all humanity and the stability of the planet. The development processes of the great emitters of greenhouse gases have transferred social and environmental costs to all the world population, especially the most impoverished ones. This article is a critical analysis of how the legal climate change regime continues to legitimize the onslaught on the atmosphere. It reflects on the need to move to a new "climate justice law", characterized by responsibilities and obligations centered on the prevention, repair, restoration and treatment of damage and related risks linked to climate change, while protecting human rights and the atmosphere, as a common interest of humanity and the Earth.</p><p><strong>Keywords: </strong>Atmosphere, climate change, common concern of humankind, climate justice law<strong></strong></p>

Article endeavors to analyze the prophetic guiding principles regarding human behaviors related to plants and trees being an important component of our environment. The discussion mainly deals with the key environmental issues emphasizing plantation and its significance for balancing the equilibrium of the environment. Additionally, it thrashes out that humans are urged to seedling the plantation even the world is to be ended in Islam. The present study is delimited to the present ecological crises faced by society and a great challenge to the globe. The current ecological problems i.e global warming and climate change are interpreted just to analyze the environmental behaviors in Hadith literature. However, a profundity descriptive study has been conducted in the most influential way to examine the prophetic rules for human behaviors related to trees and plants being environment friendly. Furthermore, the existing practices of humans related to such an environmental sphere also been aptly figure out to highlight all possible ways in the light of prophetic guidance to deal with prevailing environmental issues. Inconsistency between religious teachings and human behaviors need the keen interest of religious scholars and social scientists to carefully harmonize both for maintaining the ecological balance in nature.

Peatlands located in tropical climates are estimated to have an area of ​​11% of the total peatland on earth. The scope of ​​tropical peatland is proportional to the significant role this ecosystem plays in the stability of the earth and everything in it. Various efforts have been made to restore the condition of the peatland ecosystem, especially in tropical areas that have been affected by human activities. This study using the literature review method attempts to collect and summarize various peatland restoration efforts carried out in various countries in the world, then serve as a reference and basis for consideration in redesigning peat rewetting infrastructure. The result of this study is a canal blocking design using a PVC pipe filled with peat soil in its cavity. The layout of this PVC pipe canal blocking is designed by considering various factors. Challenges and prospects related to the idea of ​​this canal blocking with PVC pipe were also taken into consideration in the design. It is hoped that the innovation of canal blocking materials can increase resource efficiency and fund for canal blocking construction while maintaining its function and development objectives.

The Relationship

The notion of the planetary allows us to distinguish between the global of globalisation and the global of global warming. Globalisation is the process through which humans created the world we live in, how we converted the planet into a spherical human domain, at the centre of which are the human stories of technology, empires, capitalism and inequality. Global warming is what has resulted at the planetary level as intensified human consumption of the globe's resources has turned humanity into a geological agent of change. The global is 500 years old, while the planetary is as old as the age of the earth. The physical world has its own deep history: over time it has experienced profound changes. If climate change is to be addressed this mutability must be recognised – the unchanging nature of the world can no longer be taken for granted. The interview covers the rise of atmospheric sciences during the Cold War, when the Earth became, effectively, part of a comparative study of planets; the relationship between Marxism and the idea of 'deep history'; the human-made ecological disaster of bush-fires in Australia; the influence of Rohith Vemula and Rabindranath Tagore on planetary thinking and ideas about connectivity; biopower, zoe and the pandemic; and the difficulty of thinking politically about deep history.

The aetiological story of Ate, told by Agamemnon in Book 19 of the Iliad, establishes a connection between the crucial moment when the main conflict of the epic is resolved and an important moment of transition on Olympus. While tying the time of men and the time of gods together in a shared ‘ever since then’, the aetion also marks a growing divide between the two, providing a vivid stratigraphy of Iliadic time. In Hesiod’s Theogony, three aetia that explicitly invoke the poet’s present revolve around the central event of the work, the birth of Zeus: the origin of Hecate’s powers, Zeus’ marking the start of his reign by planting the stone that his father Cronus had swallowed instead of himself in the earth of Delphi, and Prometheus’ theft of fire. These aetia create a particularly meaningful present moment: one that testifies to the different types of divine time and its interaction with human time—including the complex model of time embodied by Hecate and the linearity of time introduced by Zeus—and implicates the audience in the stability of this new order of the world. Finally, in the Homeric Hymn to Hermes, the aetion of how the lyre becomes a token of Hermes’ and Apollo’s friendship imbues the present with a strong sense of the connection with the divine sphere, even while the lyre itself as the instrument accompanying the performance of the hymn vividly enacts its own continuity.

As the world warms, there is a profound need to improve projections of climate change. Although the latest Earth system models offer an unprecedented number of features, fundamental uncertainties continue to cloud our view of the future. Past climates provide the only opportunity to observe how the Earth system responds to high carbon dioxide, underlining a fundamental role for paleoclimatology in constraining future climate change. Here, we review the relevancy of paleoclimate information for climate prediction and discuss the prospects for emerging methodologies to further insights gained from past climates. Advances in proxy methods and interpretations pave the way for the use of past climates for model evaluation—a practice that we argue should be widely adopted.
